might have set up his fans wrong but he was smart to ask if he did it wrong so he could learn some good info to fix it

perfect-ly wrong he almost got me there 😂😂

Alt title: How to not create a multi-sided vacuum cleaner Edit: 400 likes thanks!

Heat rises cold sinks IS true... Without outside influence. The second you're throwing outside forces, say... From fans... You're GOING to overcome the natural settlement of air molecules. SO, as someone else here has said, you ABSOLUTELY can use bottom exhaust, and if you're GOING to place a PC on or above carpet, I'd actually RECOMMEND this approach, so long as you ensure your fan selection can produce the requisite pressure column(s).

Vacuum cleaner build 😂

are we not gonna talk about that psu cables going through the fan or is that part of the joke?

Exhausting air out of the bottom of your case is perfectly fine if you have the pressure to do it. Not really recommended, but it's not totally wrong either. Some cases actually get hotter letting the air flow out of the top.

As someone that has a business where I build custom PCs, he is MOSTLY correct. With this specific case, he's absolutely correct. HOWEVER, with other cases things can change a little bit. You do typically want to go from front to back and bottom to top, but you also need to take into consideration that you want POSITIVE (or neutral) pressure inside the case to keep from sucking in dust through every hole in the case. In his example he has 5 intake and 4 exhaust fans and the radiator is restricting air on the top 3 fans. This would definitely give the case some nice positive pressure and help keep your case clean. Now if he had a 240 radiator on the side intake and all 4 fans were unrestricted at the top, you could have a neutral or possibly negative pressure case. Now if you take a look at cases that only have 2 front intake fans but have 3 exhaust fans at the top and 1 at the back, now you a case with LOTS of negative pressure. In this situation I'd run the 2 fans up front (which hopefully have a dust filter on them) and only one fan on the rear. This will keep positive pressure in the case but will still allow for heat to rise up out of the top of the case. Your components may run a little warmer due to a little less air flow but the case will stay cleaner longer. You COULD add 1 fan up top for a little more air flow but then you'll start to get negative pressure and will want to clean your PC more often.

My dad used to say, “No one is worthless, you can always be used as a bad example.”

I actually would recommend having the back fan as intake and the two on the side as exhaust.

I had this issue. A few years into owning my pc, it started having trouble turning on, and a few weeks later, stopped working completely. Turns that the fans for my cooler were facing the wrong way, and so was one of my other fans. I had one working fan in there. Plus, while building it, I was a dumbass and forgot to take the plastic off of the cooler part that connects to my cpu. Amazed it worked for that long before breaking. Got it fixed though.

As someone with PC experience bro looks like he’s trying to make a jet engine. Pulling in air and exhausting hot air to make lift.😂

Can I mount a RTX 4090 with a Ryzen 7 5700X processor on a MSI B450M pro VDH max ?

*dirt has left the chat* the bottom fans will pick up dust over time bro 🗿

Bro just forgot that psu modular was passed through fans

My top fan is intake, its about 5 degrees cooler in this config and it has an excellent filter. This fan sits practically on top of a twin tower, dual fan, 7 pipe cooler feeding air right through the fins into the fans. Reason: The giant aluminum brick of cooler and the rear exhaust fan are super sucking all the hot air from the GPU and triple fan exhausting it out the back, no hot air ever makes it past that point. Besides, if it were exhaust my case would become positive pressure sucking in dust from every opening.

Intake everywhere, but the rear and get PVC piping from it to outside so your room doesn’t get hot

There was one ship that managed its exhaust like that, and it was IJN Kaga. It was one of four aircraft carriers sunk at the Battle of Midway. It sucked.

That's because hes living in 2034. He's going for the "tornado effect" in which the cool air comes frome every direction and mixed with the cool air, creating a swirl of mixed air, like a tornado, thus cooling the commponents under 10c.

Not forgetting if you have an odd number of fans to have more in than out. Positive pressure inside is better for keeping dust out

My back one is a intake because my cpu runs hot. It does help keep it cool other wise it would be exhaust.

Immediately after watching this, I went upstairs to check if my fans are setup correctly. It turns out, I don't even have top fans so it doesn't matter 💀

i bought 20 noctua 140mm fans and their all set to be intake, and the ultra positive air pressure turned my ATX into a micro ATX. Always wondered how those were made

I’m amazed how much of pc building is just common sense but people don’t understand.

And when you have an odd number of fans, always do more intake than output. You want positive pressure so that any gaps in the case aren’t pulling dust through spots that don’t have filters

I have the top (AIO), and front (fan) sucking air in and the back fan pushing air out the back. It makes it easier to clean the front/top with negligible impact to cooling.

Love the vids Zack

ur not gonna believe where that falling dust ends up bottom exhaust is *fine* and much preferable to bottom intake if your pc spends time on the ground

Imagine he did it correctly but everyone misunderstood him to be perfectly wrong 😂

I have PSU intake from bottom blowing out the back (isolated from everything else) Fan intake from 2x 140mm front fans Fan intake from 2x 140mm Top (drawing air in through AIO radiator on top) And 1x fan exhaust in the back 140mm 100% positive pressure and fan profile is set so front and top intake fans (Medium RPM set) ramp up together with the back exhaust fan (High RPM set) Works perfectly, dust free and everything keeps cool and quiet. The back fan takes care of moving the hot air from the AIO, MB/MEM/NVME as well as the GPU (which has a cooler setup that circulates about 25-30% of it's airflow back into the case) BeQuiet standard ATX size case and all BeQuiet fans with i7 12700k oc'd, 3800mhz-DDR4, RTX 3080 oc'd and 4x NVME & 1x Sata SSD. Good case and fan selection as well as a properly tuned fan profile is key

The argument for "following physics" with hot air rising has been a myth for many years (watch @JayzTwoCents as he's made many videos on the subject). Fans can overcome convection very easily and it makes very little difference. I would say the original setup is actually better from a thermal perspective, as the intake fans at the top have much more open space to draw the cool air in from the top, rather than the restricted space at the bottom to pull air in from under the case. Also, pushing cool air through the rad does have a slight thermal improvement to blowing warm air through it. He also has positive pressure setup with more fans intaking, however the point about sucking dust into the case is correct (which just means more maintenance, doesn't reduce performance). The only point I would say is the fans at the bottom are impeded the same way if they were intake. For me, there are too many fans blowing in different directions, which can cause a vortex effect inside the case, causing air to get trapped and cause overall ambient temps to increase. Better to remove the fans on the motherboard tray and his setup is completely fine.

Thank you for this video!

the fan above cpu heatsink can blow inwards to bring cooler air to that side of the heatsink. the warm air can find other ways to evacuate it doesnt absolutely have to be directly above the heatsink. for air cooler setup

I would add speeding up the rpm of the exhaust to accommodate for the 1 extra intake fan

That wallpaper though..lol.

To follow physics you want it to be relatively pressure neutral. Look at your fans flow and do the math period. Hot air does rise but putting your fan against that direction doesnt mean it cancels out they arent neutral forces. The other thing to consider is what your PC is on. If its on carpet make the bottom exgaust otherwise dust build up can be more of an issue.

I mean he's trying to make a rocket out of those fans.

Bro can cook pizza rolls on the back of his gpu. PC that doubles as an air fryer.

"your pc has to be on a solid surface" Me and my pc chilling in the the ocean sadly calling for help to get a table*

Ngl when I looked at the thumbnail I though it was loads of those wavy balloon people thing s

also put the radiator on the side so it doesn't take hot air to cool the cpu

If you have air cooling it’s ok to have an intake at the top so fresh air gets in your air cooler

You should put your aio on intake for better cpu temperatures

There’s a good reason why an excess for almost anything is in the back

Is the ryzen 9 7900X3D and 4090 a good combo?

Well actually if you put that rig on a carpet, its better in the 1st config as long as you put dust filters on the inake fans. Just clean the filter every once in a while.

I have that same blue pc case

bro really was just doing things fr

Shit i need to check my ps5 fans thanx dude 😎

I also think the GPU connector could be a bit cleaner

Zach this is my first time building a gaming PC tell me if I should change anything: ASUS Stix 4090(white), ASUS Strix Z790A Gaming WiFi, Corsair Dominator Titanium 32GB (7200mhz), Lian Li Galahad Il Trinity SLINF, Lian Li 011 Dynamic EVO XL, Lian Li SL-INF 120mm Fans, Lian Li 24pin Strimmer Plus V2, Lian Li Strimer Plus 18-8 VGA Cable, and ASUS ROG THOR 1000W. Tell me if I should change anything

Hot air doesn’t get a chance to rise when it’s being blown around by that many fans. It really makes bugger all difference. It’s ideal to have bottom as intake and top as exhaust purely from a dust perspective but it makes 0 difference to performance if you do it the opposite way. Hell, you could have all fans as intake.

Sisko cameo :O

I prefer to have all exhaust system with carbon filters catching all the small particles that might want to enter

Unfortunally case manufacturers rarely put radiator support in the top of the case

Some say optimal top mounting would have the one up front away from the cpu actually be intake. The other(s) should be out…..I am some, some is me…. People can argue that if they want to but it’s the coolest temps I’ve ever had without liquid so good luck convincing me.

22nd day and 66th time asking ZTT ro make an overkill ($3000+) ITX pc build guide.

Mine is Take in on back near motherboard io shield, top has exhaust, and front has a intake and exhaust. The top one is exhaust so the bottom one replaced anything

Hey Zach I have a Ryzen 5 2600 and a GeForce GTX 1070 to what should I upgrade to in the future

In my PC i have 2 front 120mm fans as intake which is the maximum that will fit. A hyper 212 blowing the hot air from the CPU straight into a rear 120mm exhaust fan. This is partly why i love having a aftermarket tower coolers. Theres also the fact that if you keep them clean they last alot longer than AIOs, and if the fan is a standard size you can replace the fan if it becomes noisy. Mind you my CPU isnt known for running hot (i5 11400f). Btw if you want to buy a tower cooler today dont buy a hyper 212 in 2024, theres better options these days that are higher quality and at the same time cheaper. Like the Arctic freezer 36, or deepcool ak400. Also Thermalright are also very good, just not available where i live.

Please make a video demonstrating how to properly use cable combs. I always see people musing them incorrectly 😭

Everything intake for me except the back as exhaust!

Air doesn’t rise all that much though on my fish tank I have 3 bottom fans pushing into my gpu 2 pushing into my cpu (reversed air cooler) and 3 exhausting (I have my 3 exhaust fans on a tighter curve to balance out the pressure a bit) and everything is getting nice cool air

I have the same case setup, what about bottom intake and the top, side and back exhaust?

So should I face the hot air outflow toward myself as a heater in winter😂?

Please make a budget build with and am5 cpu?

Hi genuine question here, recently built my first pc and I am using the vetro v5 fan. I want to know if it is set as exhaust or intake but the fan itself doesn’t have a type of indicator so I dont know if the side of the fan with the logo is classed as the intake or exhaust. Also in the manual the fan part (not the heatsink) is shown to be assembled right next to the ram sticks and I wanted to know as well if I can just put it on the other side which has more space or would it matter? Thank you for any help.

i literally only have a single removable dust filter and its on top where my radiator is mounted

In fairness, I’ve seen people advise doing air out the bottom of you have carpet because it is less dusty. Not great advice but I can see why someone would try it

i feel like the poster might not know which side of his fan is in and which is out tbh

if you have a radiator on the bottom or front, and fans are on the inside they still need to blow towards the radiator anyway.

Your way is also only half correct. You want have over pressure (or under pressure) in your case. So wen you use 3 Fans out, then use 4 in. Or if you use 3 Fans in, then use 4 out. Tepends on the case and the used components. But mostly the over pressure variant is the best.

Day 2 video 2 of asking: Question for graphics card, I got a pre built and I'm trying to upgrade it some, what are some recommendations for a upgrade from a Nvidia GeForce GTX 1660 Ti? Trying to get that far cry 6 hd graphics working good

Storytime I'm gonna be completely honest when I build a PC for the first time a placed fans In a way that all fans were taking air in but there was not a single fan taking air out so obviously temps were a little high and I was wondering what I did wrong until my dad came and helped me with that

the top 3 and the 1 rear of case should be exhaust and the rest should be in-take !!! so the water cooler has a chance !!! at least that is how I would set that tower up. so not to drag to much hot air trough the rad !!!

im still learning how to consistently build pcs and not a master builder but how do you mess up that bad

At least he knew how to mount cpu ram and gpu 😂

"Heat rises, cold falls" It's sad that even some tech tubers get this wrong.

Yes heat rises . Some processors come on fire though lmao..

What should i do for a h9 flow build with radiator on top

Eh, I'd say leave the rear fan as intake. Nothing keeps dust out like positive pressure. Also, a bottom intake isn't much better than a top intake , it just ends up sucking in all the dust that would've landed around the case. If you keep your case on a small platform not much larger than the case itself, or tucked away in a similarly small cubby, then it does provide better airflow, but if you have your PC out on top of your desk then it's going to be sucking in almost as much dust as a top intake.

You also don't want to be blowing hot air down onto your desk... Try and get the hot air above you, not around your hands

I need to adjust my top fan then. It's intake

And never the radiator on top, because its getting hotter unless you have multiple radiators

My rear fan is intake because it’s right next to my window🤷‍♂️

Is no one mentioning the 24pin connector just casually going through one of the case fans💀

Bro failed his physics class

Is 2 top intake and 1 exhaust on the back ok for a 5 5600x and a 3060

Also i have a ryzen 5 2200x and a 3060what should i uprade

Hot air rising has nothing to do with PC cooling, a small amount of fan noise can easily overcome that. The main benefit of bottom intake is the GPU doesn't recirculate its own exhaust as it will with top-down flow and to a lesser extent with front-back flow.

Hey, I have a ryzen 5 7800x3d what Gpu should I pair with it in 500 dollars

which adapter card nvme m.2 do u command?

Is that aio? Idk but is it even right thing to use AIO cooler as exhaust?

if top most right fan change to exhaust, it would be basically useless since just right below it is intake then the air just straight exhaust out isnt it? Also why so many fans for just a small case?

I need a VR capable PC that can run b. Mg, drive at max graphics. What parts do you suggest?

What's the best pc fan case

Yo so I have my AIO at the top. Is it bad if I have the fans intaking air even though all my front fans are intake too? Or should I rearrange something? Idk that part has always confused me

Then a question me who has a Fractal torrent how am I supposed to set them up since I don't have top fans but have bottom fans, I at this point in time have bottom out and front in and the only rear is the cpu cooler blowing backwards against the metal mesh that is the rear, the cpu cooler is then a noctuan NH-d15 so quite the blow is possible but yeah?

You actually don't need top fans to be exhaust if you have filters on your PC. Yeah heat rises but it's beyond negligible in a PC case. I have a Y70 case and all my fans except the rear are intake and I get great thermals. This is actually going off the same philosphy you see in massive server centers.
