Metal thermal paste also tastes better and doesnt stick to to roof of your mouth like the silicon stuff

Having nothing but a flimsy piece of plastic preventing my motherboard from being fried would keep me up at night.

"It's not going anywhere." Famous last words.

"Phase Changing" = Apple style PR language for "It Melts"

Some say he’s still trying to get the liquid metal to spread

Back in the pentium golden days we use to take turns pissing on CPUs to cool them off

Circuit board designer here: This is stupid.

The PS5 uses something similar to this. It's a horrifying idea

Computer running on high heat Him: why does it smell like burnt plastic?

Try using solder as thermal paste

The problem with liquid metal is the gallium, it eats through a lot of the copper water blocks, dust, turning on liquid into a grime that doesn’t conduct much at all

Just use transparent nail polish for being protected parts of the motherboard. And dont forget deliding process under te core heatsink cap!!

I thought it’s gonna be some incredible solution. It just ended up being: let’s put something above the metal

The risk reward just seems ridiculous. Risk destroying your motherboard. Reward a tiny bit cooler in temp than normal battle tested thermal paste.

The aerospace industry already solved this for us. It's call Honeywell PTM7950, nearly identical thermal performance as liquid metal but with zero risk to your components.

My freezer creates phase changing blocks of water.

Thermal past works just fine I’ll keep using that.

Just a note guys but not all thermal pastes are non conductive. Make sure you check the packaging before applying so know what type you have and the risks/benefits associated

Graphite pads have been out for a while. They perform better than normal paste, are solid and clean to apply, and since they dont decay or dry out, they keep their thermal properties. Best part is that they are at most $15 and last decades.

This is why I always said that people use to much thermal paste. The paste is only there to fill the air gaps, not to replace metal to metal contact.

Why not just surround a dob of the metal stuff with the silicone stuff basically making an insulated wire to conduct the heat better without risking the metal touching the other components

Cool but the plastic is now a barrier between the metal paste and the cooler.

There are also frames one can purchase. They sit snuggly around the cpu preventing overflow and can help thermal transference. It does require a very simple socket mod tho.

They should make a new type of mobo/aio socket for watercooling that can facilitate this imo

This is the dumbest idea I've ever heard of

I haven't seen something this flimsy, unpromising, and risky in a while.

it's going everywhere I can feel it

Bro removed all bass and made the trebble as high as possible on his mic

Hell yeah. A solution to a problem that’s already been solved, with additional risk of a new problem to solve if this solution fails. I like it.

I just laid a Silver-Dollar over my 12600K . Temps never go over 185 Celsius and its still worth a Buck.

Someone is going to steam mercury and lose their proverbial marbles like the Mad Hatter.

this bad boy ain't going anywhere. *Slaps it* *Goes everywhere*

No way that's keeping that all contained when in a standard upright position for long enough

This shit is terrifying, I personally could never. Feels safer just having a more intense cooling system

If you face the heat sink properly (polish the heat sink and it's atomically flat) you don't need thermal paste. Easy solution.

For those wondering, the metal he's using is called gallium.

Eh. I used liquid metal successfully for nearly three years. Was very careful about the application. You only really need both sides to be wet, so it's not like it'll go anywhere once applied. But it's a pain to reapply, stains your ihs, and application has so much room for imperfection you'll never feel certain you're getting the most out of it, or whether one day it'll short something. I switched back to noctua paste after my recent coolant change and loop clean, and using the spread method I actually can't tell the difference between the paste and the LM. Temps are basically the same, and I have peace of mind knowing my next application will be simple to clean and can't hurt anything if I use too much. Worrying about TIM really IS just obsessing over the margin of error. Don't sweat it.

Arctic Silver 5 has done me well for 15 years. I think I'll keep going with that. Lol

What if you mix small metal granules with your thermalpaste

I hope this goes mainstream

I got carried away writing this, but I had fun doing the math, so I let it go. The problem with the concept of liquid metal pastes, it essentially doesn't matter outside of benchmarking and scoring. Usually the limitation isn't the interface between the Integrated Heat Spreader and the cooler block. It's not like you have a paper thin gap you are trying to fill, often the gap is fractions that thickness. Thermal conductivity measurement is W/mK or Watt per meter-Kelvin. Essentially measuring how many watts of heat a 1 meter block of material will transfer per degree kelvin difference across the distance (1m) of block. So when you have to transfer heat across a fraction of a millimeter, that W/mK number doesn't matter as much if it's 4 like most realistic figures for paste, or 60 for liquid metal. For an intel 13900, with a 1mm gap between the IHS and cooler block (20 sheets of paper), standard Arctic MX-4 can transfer a theoretical 400W of energy at a 60 degree C differential. If you have that big a mounting gap, you don't need liquid metal, you need to fix your mounting. Taking the gap to a more reasonable 0.1mm or less turns that thermal transfer for standard Arctic MX-4 up to 4,000W. You will never hit that kind of power limit before you burn up the chip. You will also be bottlenecked by literally everything else in the system before the paste is an issue. Going to liquid metal so you can theoretically transfer 60,000W sounds cool, but it's really not a factor at all for 99% of applications. Reverse the equation, yes you can see improvement by using liquid metal. It can be statistically significant, but it's not practically significant. Using the same surface area and 0.1mm gap, if you put 1000W into the IHS with Arctic MX-4, you would see a temperature differential between the IHS and cooler block of 15 degrees. Yes, using liquid metal allows you to move that same 1kW with only a 1 degree differential. But there is no case where you are dropping 1kW from a processor outside of a crazy lab test. Maxing out the 13900k at something like 300W would give you a temp drop of 4.5 degrees between the IHS and cooler. Sure, going to liquid metal would give you a 0.3 degree temp drop. But thats not really where you are going to make up thermal headroom on your build. You are going to need a better cooler that can actually dissipate that heat long before your thermal paste matters. Yes there is more to the total system dissipation, and dropping even from 4 degrees to 1 degree between the IHS and cooler block can provide more than 4 degrees drop in die temp, sometimes even up to 10-15 degrees total reduction in die temp. As you are now moving the differential between the IHS and die closer to total system differential, which results in more dissipation from the die. But that doesn't really matter outside of 1% of use cases where you are pushing the actual limitations of the system where a couple degrees crashes the system. You aren't doing that for gaming, you are doing that for benchmarking without regard for killing the system. Just buy a good air/water cooler and you will keep 20-40 degrees thermal headroom on standard thermal paste. Or replace your old paste that has stopped working correctly, that also happens and people often attribute going to liquid metal as the reason for the improvement and not the fact they replaced 5 year old thermal paste. I hope you enjoyed reading this as much as I enjoyed doing the math for it.

Liquid metal. 10x the thermal conductivity. 1 degree difference in benchmarks. 90% you smoke your machine. Im all set thanks.

Seems practical enough

The plastic (lower heat conductivity) litterly negating the effect of the "phasechange metal" when if can prevent the leakage of the metal in a molten phase, and if not its not more secure than just dumping the liquid metal onto the CPU would have the same effect. (not worth it.)

Meanwhile plastic starts to melt and you know your motherboard screwed

Thermal paste? Real homies use toothpaste.

Man, I waited for him to squeeze the metal

I’m obsessed with this!

...did this mf just say to put a piece of plastic around my CPU?

you literally showed it doesnt fucking work, and then say its future? :D

The silicone paste lore only grows...

Sounds like robots talking between them

The Thermal Grizzly Kryosheet works great without any mess to clean.

Thermal paste isn’t necessarily meant to conduct heat super well, it’s also meant to displace air which conducts heat horribly, ensuring good contact between the cold plate and the IHS.

Correction: Thermal paste is used between the heat spreader and the cooler.

I don’t understand how that makes anything better

When you discover that gallium is solid at room temp and liquid when warm lol

I have always used and will continue to use silver infused silicone thermal paste My wife did point out while watching this video that you could put a thin layer of silicone paste around the outside of the ihs and then the liquid metal in the middle so as to achieve the same function without the goofy plastic tag

What I'm hearing is I should buy gallium and put it inside my pc

Metal + Thermal paste + water cooling

This is the dumbest, most impractical shit in my life

Didn’t look like it was spreading too well though.. Maybe needs more pressure from an actual bolt on cooler.

It took to companies this long to figure out that gallium exists

Broke my laptop, just because I didn't know it had a liquid metal instead of silicon thermal paste.

What is the music in the background ??

Use the silicone on the outside to stop liquid metal from running outwards.

I'll just stick to the paste that has been working fine since the 90s thank you

Arctic Silver Eye…love that feeling

Be careful if there is any aluminum in your system at all. If the galium touched the aluminum, it would corrode it. Not only that, but galium can remove the oxidization layer on the aluminum, which could produce hydrogen gas if any water or condensation touches it. Honestly, those facts alone don't concern me as much as the fact that galium acts like water and is very difficult to 'smoosh'. So you would be getting this metal everywhere. Plus, galium melts at temperatures higher than 83°F. So you could cause a lot of damage by leaving your hardware in the sun too long.

Honestly I just recommend the Thermal Grizzly graphite pads to people who want to build their own PC but get scared of adding the paste, it's clean, easy to apply, and doesn't require any replacement due to time as it doesn't degrade, unlike thermal pastes. If you choose the crush style pads you can get heat transfer roughly the same as the best pastes out there, and the pads have the added bonus of completely removing the concern of hotspots as the heat travels horizontally far faster than any paste and thus spreads the heat across the entire heatsink interface to improve heat transfer.

Bro was so quick, he forgot to finish the sentence.

Phase changing like Hughies Dad 💀

If its solid at room temp. There will be a gap during installation. And when it melts the will have a slight wiggle so it won’t be seated properly

"Ohh look it's a metal submarine.... I bet I can make a submarine out of bread."

Honeywell just needs to release sheets of those nutty semi-phase shift pads for some easy pocket change.

Bro is Shakespeare when talking about thermal paste

Thermal paste conducts heat well yes, but it's primary function is to remove air pockets between the CPU IHS and the cooler. You see, they CPU and cooler surface may look perfectly flat and smooth to us but if you zoom in microscopically you'll see lots of grooves and imperfections.

Boron Nitride conducts heat like Diamond and doesn't conduct electricity

You're destined for greatness.

it's essentially "soldering" the cpu to the heatsink so you need it to be quite hot to remove it easily once installed

This is really cool! Likely the phase changer is using bismuth as its substrate. Which is non-toxic. Unlike liquid metal compound using gallium; Which is highly antagonistic to aluminum and tin. It'll unseat your SMDs if it contacts the motherboard.

Legend said that he is still trying to get the liquid metal to the processor

Gallium? Then put a Aluminium Cooler on it 😂

Idk man. A pea sized drop in the center of artic silver 5 has never failed me.

Been around for over 10 years. Just never caught on because it's like 15 bucks per application. That said, used it for about 8 years straight without ever changing it, worked perfectly. Brand is indigo Xtreme. IF you decide to buy and install it, you have to do a few extra hoops on install, unlike normal thermal paste. Make sure your cpu is laying flat, and any fans/pumps are turned off, then do a CPU torture test. You'll know it's done right when your cpu instantly drops by like 50c even without the fans. Then just do a quick extra screw down on all 4 corners of the cpu heatsink to make sure you didn't get a gap when it melted.

Viscosity is important as well. Noctuas thermal paste is worse at conducting heat but still conducts more heat because it has the perfect viscosity for the cooler. It fills all the air gaps.

Another trick: use gallium as termal paste, he is very healty for your motherboard 💪💪 (Please don't do that 💀💀)

Remember kids, one of the largest consumer electronics manufacturers in the world tried this and failed spectacularly...

Unless this stuff drops temperatures by over 10 to 15° I don't feel it's worth it

Use as little paste as possible. The best heat transfer occurs when the chip is touching the heat sink directly, the paste is only there to fill any tiny uneven spots, it is Not a gasket.

Future of thermal technology: Thermal Grizzly Kryosheet

Ah. Yes. Just casually rub gallium on your aluminum heatsink. Rip.

Love this

Metal is really good. I've been using my leftover thermal paste as personal lube.

Sweet! I'm gonna use this on all my electronics that are exposed to a lot of bumps/vibrations!

Vertically mounted CPUs are laughing right now

day 23 of asking to use ice cream as thermal paste

They don't want to pay SONY to use their sponge solution 😂

I used copper slip one time works really well

Petition for mryeester to use solder as thermal paste 👇
