"Hell Yea" Let's see that loop order thing...

"Putting water into your computer" sounds exactly like putting a "fire inside your house" but of course, nuance is important and the fire is in a chimney and the water is in tubes.

Interesting anecdote; Both my PS3 and my 360 spent about 30 hours at the bottom of a pool (don't ask), and me and a coworker were able to get them running again by disassembling them, dunking everything in alcohol and letting everything dry before reassembly. That was 11 years ago and both still work.

As a middle aged man with a kid and career, I moved away from water cooling and just invest in higher end air cooling options entirely because if something goes wrong I simply don't have the time to deal with water cooling anymore and I don't want my primary rig down for weeks because I can't find the time to properly fix something. For the same reason I also like larger cases so there is plenty of room to work inside the case.

Mistakes I've made watercooling over the years: 1. Forgetting to put a drain in my loop. 2. Putting a drain in my loop with a T junction that had a super crappy ball valve attached to it that would free spin 360 degrees on the handle part of the valve instead of just going 0 degrees for on and 90 for off. This was fine for years because I was always smart enough to put a cap in the open end of the ball valve before firing the pc up, until the one time I wasn't. The ball valve was at around 89 degrees instead of 90 and it resulted in something like putting your finger on a garden hose, sprayed coolant straight into my expensive PSU, which then shorted out and died. 3. Thinking I would be fine just diluting my loop of premix coolant with distilled water over and over to the point where it was probably 1/3 premix, 2/3 distilled water. Turns out the chemicals in premix are super important and they stop algae growth among other things. Clogged the loop with gross algae schmoo that made me replace 2 rads and my pump. 4. Used Corsair soft tubing. This stuff is garbage that will kink up super easily and impede flow in your loop. I hate recommending EK products now but their soft tubing is the best I have ever used. I will never put distilled water in my loop again unless it is to be mixed at the appropriate ratio with a concentrate. Buy enough coolant to sustain your loop until fluid change time, it's worth it.

Yes do that temperature comparison.

Perspective/tips from someone whose first ever custom loop is now 6 months old: If you're able to afford a custom loop and feel like you're ready to take the plunge - just do it, it's so much fun. If you want to 'dip your toe in the coolant', try doing a simple loop for just your CPU as this will be the cheapest and will still look great, as long as you plan it out well. Also, have fun with the preliminary stuff, like research - do as much as you can, as the success of your build is largely determined by the research phase. Plan out your loop order on paper in a very rough fashion, then when you have decided on all the parts you want to buy, try doing a more detailed drawing of what you hope it will look like - remember, actually building it is nothing like what you plan in your head - I had to make tons of changes due to small clearance issues in my PC case. Before getting over-excited about the build itself, try to think realistically about what you are trying to cool and the overall loop arrangement - I thought I could cool a 4090 and 7800X3D with only one 360 rad, and soon found out what 60 degree C coolant temps looked like! I had to get another 360 and partially tear down my loop so my pump wasn't destroyed (60 degree max operating temp)! The Corsair Lab channel has a great video on loop layout presented by Greg Salazar. Similar to above, try to think about how you are going to control your setup - are you going to use an expensive suite from Aquacomputer? Are you just going to set-and-forget by having your BIOS keep the pump at a steady speed? Are you going to let your fans ramp up and down with GPU/CPU usage, or are you going to add a temp sensor to your loop and have the fans control their speed based upon liquid temps? This area can get really out of hand in terms of complexity, so you might not want to leave it until just after you've finished testing your loop to decide how you want your loop to behave in terms of fans and pump! Look at Jay's old videos on fittings, coolant and build layout - I got tons of info here. Remember the 24 pin jumper for the motherboard! - you need this to test your pump/loop before actually booting the PC (it keeps the power 'isolated' to just the pump so the PC will not boot up, just your loop). Remember to try to add a drain valve to the lowest point in your loop! - If you don't how will you change your coolant easily? Remember to thoroughly clean your radiators before building! - there are tons of videos on this. The time spent washing the crud from the new radiators will pay off in the long run. Do not use the style of pressure tester you see Jay using! - The bike-pump, all-in-one style is very prone to leaking from the pump section and I had this problem. It caused me such a headache because it was my first build and I was lacking in confidence and experience, so I was blindly trusting the pressure tester, so I thought I had a leak when I didn't. Get the 2-part kind like the Dr Drop Pressure tester - the kind where the pump is separate from the gauge! Don't bother trying to mix your own coolant - the amount of comments I saw under the research videos I watched where people were complaining about general gunk build-up, growth in the fluid and damaged nickel plating on the CPU/GPU blocks was crazy - the common factor seemed to be that they were all making up their own coolant. Just get a premixed from a trusted brand. As Jay said, if you want an easier time, just go for rubber tubing - If you want to 'upgrade' to hard tubing later on, it will only require buying new fittings - the least expensive main component in your loop. Take your time with the build and don't push yourself too much, as this will cause mistakes. Leave it till tomorrow if you're fatigued or getting frustrated. This will also buy you more time to think about your build as it's taking shape - most of the best alterations I made to my build were this kind. As I said at the top - just have fun with it and enjoy every step in the process. The research, shopping, planning and building phases are all fun in their own way and you never know when/if you'll be able to do another build (the expense!).

I really appreciate channels like yours that try to give the viewer the confidence that they can do a task they thought was hard and beyond their skill level. I can't tell you how many videos I've watched to figure out how to fix my car, household appliance, or anything else. I've built computers for 24 years and have never touched water cooling until a few weeks ago when I installed an AIO in my system. Upgraded my AMD CPU and the air cooler just couldn't keep up. It was cheaper to get a 360mm AIO than a good air cooler. So thank you for being one of those channels that tries to boost confidence in people.

20:42 Jay's humor when calling himself out for the way he said something is always funny. It was a long day, but this particular line about "or your fingers, well *and* your fingers" had me laughing out loud for a bit.

A lot of people don't understand that 300 watts of heat is 300 watts of heat no matter what the actual temperature is or in other words 300 watts of heat at 70C = 300 watts of heat at 80C However the advantage of 300 watts at 70C is your CPU or GPU can clock a little bit faster but even that difference only means a couple percent increase in FPS or 1 - 3 FPS which is essentially unnoticeable in actual gameplay.

Once in 2001 I had a PC in a high tower which was on the floor and my dog ​​then decided to piss in to my pc and the cabinet was open so everything inside was completely wet with piss. The craziest thing was that there was power but it wasn't on, I removed the power cable and removed all the cables from it and rinsed it with distilled water inside and dried it. When I turned my PC back on it worked perfectly, I guess it just proves that electronics are tougher than you imagine.

Based on a Jayz2cents video, I sucessully built my first custom loop with bending hard clear acrylic including CPU, GPU, VRMs, memory and 2 360 radiators. 2 years later it is still going strong. Thank Jayz!

Mixed metals and soft tubing loop with dual pumps, 360 and 120 mm rads, the fluid is an automotive antifreeze, de-ionized water and hy-per cool mix, I blast it every few months with an aquarium UV light to sterilize the fluid and kill any growth. It's been running almost 5 years - no corrosion, no growth or buildup, no fluid changes just keep it topped up. Your channel really got me started into PC liquid cooling, thanks Jay!

Jay I water cooled my PC long before anything was available. I made my own parts without any help back around 1990. I just understood that thermal mass is the bottom line. Yes my first time used a heater core out of an 84 cavalier and a fishtank pump. Blocks were all aluminum blocks with fittings drilled in and some fins cut in for passive heat dissipation. No there were no fans on any of it because there was no such thing as motherboard headers. But I could push my system way faster than stock. No temp monitoring in those days so who knows what the real world benefits were. My current system is water cooled also. Nothing fancy expensive it just works.

Watching Jay videos is literally like getting advice from a dad. It has such a warm tone to it with some excellent advice.

Would love to see you make a budget watercooled build - Something with not over the top specs but still enough to warrant water cooling, what value that would be and what performance watercooling a system like that would offer etc. I feel like that would be interesting.

Just got a new case and added a new rad to my loop. No need to upgrade any parts, but I'm glad I got in and added new fluid and cleaned the blocks.. these barrow and barrowch fittings have held up just fine. Reusing parts is awesome

I’ve been doing custom loops in my personal rig for the last seven years and it started with your videos. I watched your videos over and over and over and finally decided to take the leap and do soft to me. I still do soft tubing, but like you, I’ve switched to the black tubing because of the plasticizer issue.

1. Watercooling doesn't make your room colder 2. Leaks doesn't always ruin a system (not using tap water) 3. Cheap options for loop parts now exist 4. LOOP ORDER DOES NOT MATTER (because of the small size of a PC loop and small delta of temps) 5. Making a custom loop is not that hard especially for soft tubing

Guys... look at the profile pic on some of the comments so your brain can realize that it's a bot And report it! Most times it's a pretty lady or a butt pic anyway so it's Not hard to recognise. Nevermind that the account is often less than 1-2 days old! Don't be dummies and comment / like its comment... just report or ignore them 🤷‍♂️

Dude, I have been watching you for many years and am glad that you are getting back to your roots. All this fanboy non-sense and manufacturer drama is not interesting to me at all. I love when you build custom water-cooled systems. All my computers are water cooled. I keep reusing and upgrading my water-cooling components. Some of the computers have had up to 5 or six different motherboards over the years. Please get back to your roots. THX IE: Custom built NZXT H440 case from 2015 with 6mm tempered acrylic door, gutted front drive area and made panels for PS basement, floor and side to mount pump/reservoir.

As a recovering Chemical Engineering major that did lots of heat exchanger design problems in school, I'd very much like to see inlet and outlet temperature probes on all the components in your water loop and in as many different configurations as possible. Especially interested in getting supply and return temps on as many different models of radiator as possible under differing load conditions.

I had no knowledge or experience in watercooling computers. This channel gave me the itch to customize my own PC loop, and I love it. When this thing is finally ready for an upgrade, I'll for sure water cool my next build as well. It is a great way to make a build completely your own.

I did a custom loop for the first time a few months ago, and hearing that a leak isn't necessarily instant system death is highly comforting. I feel like I knew that in the back of my head, but it's still nice to *hear* it. Also just glad for this channel prepping me for years before I tried a loop myself, turned out pretty great and I didn't forget to buy a single thing!

It was an expensive initial cost, but I don't regret going custom loop one bit. Been using the same pump/res combo, fittings, soft tubing, and CPU block for multiple years now. The GPU blocks when I decide to upgrade are a punch in the gut, but I accept it. My main reasoning for continuing to have a custom loop in my system is silence. 2 60mm 360 rads and a 40mm 280 rad in my system cooling a 14700k and a 7900xtx.

Jay is definitely looking better, that's good. I water cool my pc because it cut the noise way down. Sounded like a jet starting up with the 4090. Now nice and quiet with better cooling.

Making your space warmer is a great feature of watercooling. The spot were I game has a normal temp of 5-20C. So in winter my cooling system is so efficient that it keeps my room at a fully livable 17C. Summer time is a biy worse, but opening windows generally works well. :)

I would ABSOLUTELY LOVE a video on that loop order deep dive on the Scientific aspects of how the order affects the temps of the fluids! Sounds like an amazing video!!!

Once the Light Base 900/600 come out, there are going to be some very incredible looking horizontal layout builds in that thing. I'm looking forward to it.

I remember my first custom loop, I had to refinance my house

I just love the look of water cooling, can be unnecessary if you *DON’T* configure correctly. But seeing a well thought plain loop with nice bends , beautiful!! . Next loop is gonna be black tubing for sure , 6 months left till next flush !!!!!

My best myth bust was trying to explain to people that the loop will saturate and all components will receive the same temperatures. After trying to argue the point to exhaustion and annoyance, I just finally started referring people to your channel and videos. Thank you and your team for the work you do and all of the great video's and insight. You are a boon not only for us experienced types, but also for beginners. Please continue to do what you do, and we all look forward to the new expansion.

What a timing, i was just looking for aome watercooling videos from you :D

"Moooaan custom water loops are a pain..." Use soft tubing Use quick disconnects Use an AIO instead? Switch components less maybe? I could go on 😂 That all said, there are deffinitely downsides of course but I would say you only go full custom if you get the top of the line stuff 🤷‍♂️

Yes! Do a whole series on water cooling, please. We need updated information.

So this channel was a major inspiration for my first water-cooled PC. It even got me into modding my PC. I don't think I'll ever go back to air.

I still argue that if you can have a radiator after each component, it helps, but jay isnt wrong. These devices aren't going to melt themselves even when the pump stops running, and youre only talking about a degree or two, AND if you have enough heat transfer capacity, you'll be far below 40C let alone 70C, so there is NO PRESSURE to have a certain loop order, it doesn't need to ideally optimized with sanded IHS, ans liquid metal, etc etc. Using the right water is key, and... this is the most important part:PRESSURE TEST YOUR LOOP WITH AIR FIRST. The number of times i had one or two fittings just 1/8th of a turn too loose

Jay, do a review on the Aquacomputer Leakshield. Been running it on my soft tube setup and once you get it dialed in it’s amazing. Absolutely zero worries of any sort of water leak throughout the system. Pulling 330mbar of vacuum on the loop and not having any tubes collapsing.

I used an Aveks water block on my last custom loop, $20 from Amazon for an all-copper water block that keeps my 11700K @ 5.3GHz running just fine. I miss the old days of making a water block out of a heatsink, plexiglass, and glue, using a K5 Blazer heater core for a radiator, and a pond pump plumbed to an automotive coolant overflow bottle but I'm glad we have the options we do now.

Jay is so real. Though I knew about these myths, it's still nice to hear him speak about them. Although I'm not an expert, I like to do research before I purchase items and/or perform project ideas. However, I did learn a few things while watching this video. And as a owner of a mini-itx PC with a full custom water loop, it's pretty important knowledge. Recently, I moved my PC into the Fractal Mood.

I have actually cooled my PC room with water cooling. I have no pump or reservoir in the PC, I have quick disconnects on the back of the machine, and run EPDM tubing up to the corner of the wall and ceiling, through a wall, down the hall, and into my house's central air return. the pump, and radiator are on a 3d printed stand, and a small file server PC is also in there, cooled on the same loop. The 480mm radiator fans and pump are powered by a small independent wall plug 12v adapter. my pc room temps dropped around 10-12f just by pumping the heat out of the room. it's a four liter system.

You might try purified water plus a small amount of copper sulfate. We use it in agriculture to keep algae from growing in water storage tanks.

I completed my own water loop a week back. I bent hardline tubbing. I owe this channel a lot for the motivation and quick tips when bending. If I can do it, so can you. I had many reservations when approaching this project. But I powered through and my new rig is B-E-A-Utiful.

Jay, your channel is what got me into watercooling, and I've loved it since! I had a leak from my CPU block onto my graphics card, and I only noticed when I took the system apart to clean it; the system ran completely fine. 😅

A more efficient transfer of heat will only make the space hotter if it means the components can run at higher power limits. How fast heat transfers doesn't have an effect on the total energy outputted unless some other factor changes. At most it might affect how fast your room gets hot, but that's about it.

After watching this channel for a long while, I built a custom loop for my 3080TI. Eventually, I needed to clean my loop, touch-up the thermal paste... basic maintenance, really. I used a bunch of isopropyl alcohol during the cleaning and when I put everything back together, it looked like I killed my card. In the end, I just hadn't waited long enough for the alcohol to evaporate. Isopropyl alcohol evaporates quickly, but impurities can mean a much longer dry time than you expect.

Man, the first thing I did after building my water cooled rig was upgrade the room to have an integrated AC unit, I would almost say its essential. Those free standing units are OK but they create almost as much heat as they remove, not to mention the noise.

Always feel free to hit us up with that water cooling content Jay. Your channel is one of the key contributors to pushing me to finally trying to make my own custom loop. That was around six-seven years ago and I am never going back. Yeah it is pricey, but it gives you the best possible pc temps (components anyway), cuts my heating bill in winter (lol), is kinda stressful but fun to do, and gives you a PC that is unique to you.

OK, now do a video about water cooling myths that are TRUE. 😏

I just want a water blocked GPU without spending an extra $300 for it. I swear it used to only cost like $150. Maybe I’m remembering wrong

From a complete novice: if you watch a couple of Jayz water cooling videos, they covered everything I needed to know. Hardline isn't hard; just be sure to have the right tools!

Working on my first loop right now and this channel is the only place I go for information. Thanks again jay

Let's GO! I hope your health is getting better Jay.

Really wanna do my first custom loop build on my first non prebuilt pc

Hell yeah. A deep dive would be helpful. I'm soon to start my first water cooling loop with hard tubing, and your videos have always been helpful to me on this pc building journey.

“Ambient temperature is important” My Iraqi ass:💀

I started water cooling around the same time, I didn't even hear of EK until about 10 years ago, I was dedicated to the parts I had for all of that time, a decade or so, then I upgraded everything and wow, it got expensive in that time! I'm sitting here chanting Deep Dive, Deep Dive, because there are too many people who make it so us more experienced guys have to work so much harder to keep the information correct.

Funny but, this video actually taught me to appreciate water in my country a bit more, hearing him talking about tap water and "how dirty it is", actually in my country everyone drinks tap water since its really clean over here.

I will always use black EPDM rubber tube. I’ve been reusing the same sets of tube and just trimming for new builds since 2018. Same fittings just cleaned them. Saved me SO much money over the years when doing water cooling.

Water cooling is fine, if you actually need that level of cooling. Most really don't. The one thing that isn't a myth is that custom loops are usually more expense than function. Heat has to go somewhere so it is going into your room unless you can pump it outside. It doesn't just go away.

If your looking toward water cooling to keep your space cooler, you're looking at moving the radiator out the window. There is a series of additional challenges to move the heated water out the window decently such as pump pressure, solar heat, window air sealing, and so on.

I have been water cooling since 2016 thanks to your videos. Thank you. I would love to see some updated videos to share with people.

My first video I watched of yours what “how to water cool a computer.” Because of you I’ve been water cooling for 11 years. External rad(s) still, Basic-B bitspower barbs, barb clamps, Primochill Advanced LRT soft tubing, PHN PT Nuke (still), distilled water. Never a leak, never a problem with growth, plasticizer leaching, or anything. Multiple upgrades, have not had any issue, reused some tubes just down to laziness. Started with an Intel 4570T, going strong now with an AMD 3950X, basically the same setup, still the same Lian Li VCR lookin case.

I have no problem with using water cooling. My problem is the amount of effort and money it costs to build a custom loop. The idea is great but the amount of maintenance needed is beyond my idea of fun! I use an AIO and it's fine. Why would I put so much effort into building a custom loop that won't last as long as my AIO? If you find it fun to build such a system, then good luck to you! My present system includes a Corsair 360 AIO and I'm happy with the result. At present I've been using it for 9 months and I expect to keep it for at least another 2 years no matter what other components I upgrade. 😇😇😇

One reason I don’t like custom water cooling is just the fact if you got a new cpu and you want to upgrade you gotta take apart all that stuff compared to just a air cooler with lots of fans

I don't water cool for reasons 1. No need in a closed case unless its an open bench. 2. Too many point of failures 3. Min maintaince required

Hey Jay, I did a micro center run yesterday and wore my dad bod and pc mods shirt and actually got complimented on it. Sure as heck made my day.

I think I believed all of these misconceptions before building my own itx 4090 build. Jay is king of water-cooling.

I had a brand new system with brand new water cooling. Drips from CPU block to graphics card smoked the whole system and burned pins at GPU. To my amazement, and major props, Thermaltake paid me the cost of my new system. I jammed everything in a box and mailed it back to Thermaltake. Glad to still see Thermaltake still around because that's a company with serious integrity. This was a long time ago, I have no idea what the coolant solution I was using, but I wouldn't be good with anything flowing into components. The industry needs to focus on refrigerant cooling without condensation.

I also bought a load of fittings and most of them are Dracaena and they do look fairly good and I would have never of thought to do so but after seeing you video a while back and actually having them in my hands they do look quite good even next to the corsair parts I have. The only reason I did end up buying them was because of the EKWB EK-Tube ZMT having an I/D of 9mm rather than 10mm that my current tubing has, and the Barb fittings I bought come with 13mm hose clamps which are to small to stretch round the hose when fitting on the barb so you will need bigger clamps . The 15mm ones I bought do fit and they are very snug and are wider but does sit between the barb and the knurled area of the fitting. So here's my part list that will allow me to redo my loop. *KEALBAUS 15Pcs Barb Fitting Water Cooling Radiator for G1/4 Chromed Copper Water-Cooled Heat Sink for Pc Computer* £14.40 *Sourcing map 10pcs 15mm Spring Band Type Action Fuel/Silicone Vacuum Hose Pipe Clamp Low Pressure Air Clip Clamp, Nickel Plated* £5.69 *Dracaena 6 pack G1/4" thread, Male to Male Mini Extender Fitting with tighten O-ring, Compression fitting for Computer Water Cooling System, Silver* £24.96 *Sourcing map Male to Female Extender Fitting G1/4 x 25mm for Water Cooling System Silver Tone 6pcs* £14.99 *Dracaena 6 pack G1/4" thread Male to Female Extender Fitting, 90° Rotary Enhance Multi-Link Adapter Fitting for Computer Water Cooling System, Silver* £19.99 *Richer-R G1/4 Water Fitting Splitter, G1/4 Thread 3 Way T Shape Fitting Splitter Adapter for PC Water Cooling System* £5.96 *Corsair Hydro X Series XF Fill/Drain Valve - Chrome (CX-9055020-WW)* £18.39

The easiest way to explain how much your PC will heat up your room is with watts like you mentioned. A pc consuming 600 watts of power is a 600 watt space heater regardless of how hot the chip of your CPU or GPU is. 600 watts is 600 watts.

You know, around the time I built my current system (although a bit late to keep me from one or two mistakes) I found your channel and used your various tips and hints for a lot of tweaking and improving and stuff. What you also managed is completely (well almost) take away my reservations against watercooling. I always found it cool, but it seemed to me very risky and I never dared try it. Now I'm currently running my first AiO (mainly because my cheap-ish case fans were making expensive noises and there was a sale and I got a 280 BeQuiet AiO for about the same it'd have cost me to get higher-quality replacement case fans). My next build (if all goes well later this year, otherwise sometime next year) will be my first custom watercooled build. But, even though you're "the watercooling guy" - you've already helped me no end in improving and troubleshooting my current build and also getting rid of some stuff I didn't need. I also really like your way of presenting and the team, so thanks a lot and I'll be looking forward to the next video(s). Cheers from Germany!

Yes. I want to see the temperature comparison loop. Also, this was great. I learned a lot and I’m thinking about building a new PC and water cooling it soon.

Thanks for all this information. Never wanted to try water cooling over the fear of a leak happening and drying the whole system. Maybe I’ll give it a try later this year with a new build.

I just finished my first custom loop, biggest reason being loud GPU fans, it wasn't cheap but also didn't break the bank, went with almost full Alphacool build, and luckily I can reuse the block for a long time to come, quite happy with the results, still need to buy an leakshield for the peace of mind. Considering custom loop? feel free to ask me if you have any questions.

Listening to an out-pouring of your knowledge and experience is excellent, and inspiring, Jay! Thanks.

I love your water cooling videos. I learned and built my first hardline custom build by watching your videos. More please. Thanks.

Definitely want to see that temperature comparison video you mentioned. Would be interesting to see if any surprises come up.

Yeah, coolers don't cool, they move heat. Home AC systems move heat from inside to outside.

Jayz Science Episodes are always so entertaining and helpful to newer builders. I'd be interested in a loop order temp comparison.

Electrical contact cleaner is what I use every Year. It cleans everything with no residue. It works on fans too.

"It's hot as balls". I'm going to send a message to Stephanie Abrams on The Weather Channel... I want her to start using this phrase to describe the summer weather...

Just imagine doing water cooling in the very late 90's early 2000's here in the UK

Would love to see the 'between component' temp measurement deep drive. Not because I think it's necessarily important, I've seen aspects of it enough to know you're right, but it'd be cool to see the numbers and everything. Always love the science side of things when you guys tackle it.

Good advice, but also a nice trip down memory lane. I was looking at one of my old builds up on the shelf today and thinking about how things have changed. It has soft Tygon (food-grade) tubing, an Eheim aquarium pump, and a Black Ice 1x120mm radiator. I've also been through disasters like a massive fluid dump and I had to clean glycol off of everything (it all survived) and a Swiftech block that galvanically corroded to hell.

Yeh Jay, that loop with temp in/out readings sounds like a great topic to watch.

This video brings around a question I've been dying to ask on the rtfm show. My question is what's the difference in temps between low and high fin density radiators? Love all your content jay and the team.

A few more myths… 1. Water cooling: Cost VS any level of return. 2. How long before the water cooling almost effectively maxes out after turning on? 3. Possibility of damaging components

Jay, I would love to see a practical build, for those whose priorities are 1) quiet, 2) easy service, 3) smaller and lightweight. In particular, I am thinking Koolance quick disconnect fittings. Small diameter rubber neoprene hose - either 1/4” or 3/8” inner diameter hose. Easy removal of GPU, CPU, change of NVME M.2 without draining loop. Consider reservoir/pump with 2 manifolds - in and out. Connect parallel loops for each item, rads, CPU, GPU, to the manifolds - no serial loops. Using 1/4” diameter rubber hose is so flexible and corresponding quick connectors are small (but expensive). 4/5 parallel loops have more area than typical 10 mm hard tubing, so pressure loss should not be an issue. May need a controllable valve to balance flows so low pressure drop rads don’t take all of the fluid flow.

Thanks a lot Jay! I really would love to do an open loop build but its just daunting. This made it seem a lot less so!

Always love your water cooled adventures, let's me live vicariously through you b/c I personally cant afford to do it myself.

Great video! I can't wait for the deep dive to see if it aligns with what I expect. Also black soft tube can look realy cool I think.

For a reassuring horror story regarding watercooling leaks, here's a "sample size one" on how not that bad things are: I've watercooled for a long time and at one point I had two Radeon 5770s (I think) in Crossfire. Due to a mix of not great acrylic, overtightening fittings and harsh environmental conditions, one of the blocks got some bad cracks around the fitting and leaked a not insignificant amount. This was a horizontal motherboard layout too (it was an Antec Skeleton case), so by the time I noticed, there was actually a small pool of water on my motherboard, right where the PCIe slots were and the computer was on at the time As I kept my panic internal, I just calmly assessed the situation, turned the computer off, drained the loop, removed the videocards, dried off the motherboard the best I could and returned the original stock coolers to the GPUs. I think I gave the motherboard a two or three days to dry off proper before I actually started using it again and that computer was fine. I used that motherboard AND those GPUs for like... 3-5 years after. With the GPUs, I ordered acetal tops for the blocks and looped them back in again once they arrived So yeah, this is almost a worst case scenario sort of deal and I didn't lose a single component. Lucked out, for sure (there was plenty of dust on that mobo, I'm pretty sure) but.... yeah, far from "instant death sentence" sort of deal. Way safer than having a regular stock cooled 40-series fire hazard in your system, apparently =P

Reasons why I'm using a Noctua air cooler instead: Noise (it's simply quieter than multiple fans +pump) Price (being Noctua it isn't much cheaper but still...) Mainboard component cooling (it's even a top blower for additional cooling) Reliability (I don't have to worry about replacing water or leakage, +Noctua fans outlive most systems) Overkill (My CPU only draws 60W)

I used to use tygon clear tubing and swaglok fittings when I built loops 20+ years ago. Modern fittings are so cheap and good, folks have no idea how good thing are these days. Definitely something everyone should try if they're interested. Everything is easy and you can get everything off the shelf, no more DIY required.

You don't need a whole video to prove that loop order doesn't matter. If you have a loop with a flow rate of 1 GPM (or about 3.8 L/min), you have 500 W of heat added to the loop, you can calculate the maximum temperature change of the water. You need about 4180 J to heat up 1 kg of water by 1 degree celcius. 3.8 L/min is about 0.063 L or 0.063 kg per second. To heat up that amount of water by a degree, you need about 260 J. Since that's in a second, that's 260 W. 500 W will thus heat up the water by about 2 degrees, at 1 GPM and 500 W.

in 2008 I lost some expensive parts, not directly by water contact, but because the pump broke and the water literally boiled in the blocks. (Thermal throttling was a thing on CPU's then, but GPU's and motherboard chipsets apparently not.) The pump itself died because of water though, a plexiglass part cracked and let water into the electronics side which corroded, stopping the water flow. Never again plexiglass. And never had an issue since, been watercooling for 2 decades. Loop order doesn't matter if you have enough pressure to flow properly. The whole 'thing' is from when people were using pond pumps that barely put out any pressure, and needed huge inflexible hoses to flow any water at all. Liang DDC and D5 pumps fixed that for a lot of people, and we've gotten so spoiled with all the good options since. :) Related, a myth, you "need" 1/2" ID hose for watercooling. :'D

Id love to see the temp comp video! Think that would be very informative and great to watch you guys do. I enjoy all the content you all put out though!

Not only the increased heat transfer can heat up your room faster with watercooling, the lower component temperature also can lead to higher boosts and power consumption and this way increase the output even further. And for cleaning after a leak, I have a colleague whose GPU tube popped off in use due to overpressure and flooding his card. I disassembled it for him, used pressurised air to blow the water from below the components like core and VRAM, flushed it with destilled water, pressurised air again, 99% rubbing alcohol and pressurised air again. It works without issues since. Luckily he didn’t kill it when he powered it on before I cleaned it, he just got a blocky image from the water under at least one VRAM chip.

I’ve been waiting a long time for jay to get back into water cooling videos
