@@cemsengul16 It works nearly identical to liquid metal in both cases.

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.
I thought it’s gonna be some incredible solution. It just ended up being: let’s put something above the metal
Sometimes the simple solutions are all you need.
The heatsink goes above the metal. The thermal paste fills a very small airgap between the CPU's heat spreader and the heatsink.
@@MrAndrewAllen I would prefer to hear derBauers opinion . The extra plastic ...could increase the "forgotthename" height....Also ..wouldn't the metal just flow out of it ...because the plastic will always have small openings.
There is actually another problem with liquid metal not mentioned in the video which is what it does to aluminium (which is kinda important considering how much cooling apparatuses use alumium in the part that makes contact with the thermal paste ).
Also ... I think derBauer has a better solution ....

You may use the thermal past, but I'm looking forward to the thermal future!
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
This. This video is very misleading. There are many silicone based thermal materials that are VERY electrically conductive. It’s the particles inside that make the difference, not the base liquid.
Not to mention just because it isn’t conductive at DC voltage doesn’t mean it’s not conductive to AC or RF circuits
@@ISuckUnderPressureArctic has one of those called Arctic Silver. It used pure silver instead of silicon so it techically last forever but also dangerously conductive like liquid metal does
@@sihamhamda47 while you are kinda right, they got you with their marketing.
It contains silver that is 99.9% pure. But the paste isn’t 99.9% silver.
It’s mixed with zinc oxide, boron nitride, and aluminum oxide as well as some sort of non silicone based oil.
It is 88% thermally conductive filler by weight, and 12% suspension media by weight.
Here is the SDS for Arctic Silver 5
www.arcticsilver.com/PDF/AS5_SDS.pdf
True, there are also some that’s while not electrically conductive, but still electrically capacitive. Which can be just as dangerous.
Arctic Silver 5 is the perfect example of this, hence why its popularity has dropped quite a lot nowadays.
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
It eats basically everything metalic, turnit id into useless amalgam. A nightmare of any repairman. Though usually boards damaged by this concoction can work only as donor boards and even then with caution.
The PS5 uses something similar to this.
It's a horrifying idea
Cool but the plastic is now a barrier between the metal paste and the cooler.
Most of the heat is generated starting from the center of the CPU die, spreading outward. So yes, plastic would be in the way, but i think it would be okay because it's towards the edge of the die
@@iamjoehill plastic creates a gap between CPU and cooler. You need more liquid metal to fill that gap. AT BEST you'll get same temperatures as from any shitty paste.
@@Danger1225yeah silly aint it.
They use thermal conductivity as some kind of marketing thing.
But the gap should be extremely small.
The imperfections should be filled by a material. Making it a bigger gap doesn't work.
I once tried polishing the cpu and cooler. At first it worked better. But the paste couldn't grip so it moved and became worse.
Just use good paste and not too much.
Also this cpu has a heatspreader, with paste under it.
@@MrSpacelyy with more ideal surfaces and probably too much force in tightening your cooler it is possible that paste pumped out. Try to tighten cooler more evenly, or use thermal paste with phase change (Honeywell for example). It is not ideal, but can solve this problem.
@@Danger1225 Nah. on average you'll see about 2~3c lower than the best pastes on the market, some reports up to 5c. Tomshardware did a full on review on em all.
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
My thoughts exactly.
Sane ppl think alike
Glad I found you guys
Uneven conduction of heat could warp the cpu
The point of applying a paste is to distribute the insulation relatively evenly, doing what you suggest would concentrate the heat in one area and potentially cause problems down the line. Most "obvious" solutions don't work when we are dealing with a system this complex because there are always other factors to think about
Ah. Yes. Just casually rub gallium on your aluminum heatsink. Rip.
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.

For those wondering, the metal he's using is called gallium.
Liquid metal. 10x the thermal conductivity. 1 degree difference in benchmarks. 90% you smoke your machine. Im all set thanks.
with CPU the risk is minimal, the socket is quite far away from all the components.
With GPU, just cover all the components near the die with some varnish
for me the temp improvement was around 5.
Definitely more than 1 degree difference, but only if you delid the CPU. Otherwise yeah, you can only improve temps so much with changing TIMs.
Bullshit. Go back to school kiddo, lm works and I'm seeing big temp diffs on my laptop. Idle 10c, max load 40w more sustained power.
On my laptop the difference was 15C. Just used thermal grizzly shielding for the die and i feel comfortable throwing it around in my bag all day
For some people, the performance improvement is worth the risk because if you're careful and you have a steady hand, it's not that hard to install flawlessly
Arctic Silver 5 has done me well for 15 years. I think I'll keep going with that. Lol
Sure, it works, but liquid metal is superior in heat transfer. I'm scared af to use to, so I'mma keep using my regular thermal paste, but no doubt it's superior
Try the Artic Mx-6, that thing is great.
I'm not gonna lie I thought you meant you've gone 15 years without replacing it at first lmao
Agreed only reason would be some crazy over clocks that's more of a crazy hobby.
Or you could just apply it correctly.
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

@@LarryBenkinThat suggests to me that if you have a PS5 you should never fuck with it's orientation, right? Because if it's not in the intended position it might not contain the liquid metal as efficiently?
@@TheFounderUtopiaThat used to be an issue yes, few ps5's that were stood up leaked the liquid metal, but with some tweaking they seem to have completely removed this issue since january 2022 as far as I'm aware.
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.
TBH, the only people who should be using liquid metal are overclockers. If you really want better thermals, use a better CPU fan or better yet use a liquid cooler.
Try using Honeywell's PTM 7950. It has the same thermal conductivity as the high end thermal paste but has much longer lifespan (it can last 8-10 years before degrading)
Aint reasing allat 😂
What metal did u use
@@juhis5936 Conductonaut
My last two builds used a high-end thermal pad instead of paste (Thermal Grizzly Kryosheet). Works great & won't degrade over time.
If anyone ever needs this hack, late night I was building a desktop and didn't notice I was out of thermal paste. I went down to the local automotive part store and grabbed some spark plug anti seize to use instead. They have the same chemical compound and my desktop has been running at normal temps for 6 years now and I never shut it down except to restart or from a power outage. Figured someone could use this hack. It's also about half the price as thermal paste.
I just laid a Silver-Dollar over my 12600K . Temps never go over 185 Celsius and its still worth a Buck.

Yo, good to know, I'm building a 12600k into a PC right now, I'll skip the cooler and save $40 👍
That’s good, I was worried about my cpu reaching 500 degree Celsius again and catching my house on fire
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.
I enjoyed reading this
This is a great explanation, and brought back memories from my heat transfer class
It matters for laptops
@@danielshort118 no, laptops are the same as desktops when it comes to transferring heat out of the cpu. The problem with laptops is they can’t exhaust enough heat because they don’t have room for high surface area coolers.
This was a really good read 👌🏻
Electric tape around the socket is the best way to prevent the liquid metal from doing anything. Not completely in the clear but just about the best you can do
Everyone seems to have forgotten how to apply thermal paste.
Frankly, less is more. It's purpose is to eliminate any gaps in the contact between the one and the heat sink, with that in mind there shouldn't be a layer that completely conceals the ihs.

@Soccerrockker6 it is better tho I use it in my laptop
The surface has to be super clean and it needs some heat. Liquid metal works super good, but it's annoying to get applied to start with. I use it and once you get it started then it's easy, but that cpu looked like it was just wiped clean of previous silicon. It has to be super clean.
Meanwhile plastic starts to melt and you know your motherboard screwed

i used liquid metal on my red devil 6900xt vertically mounted (coated around the socket with clear nail polish) lasted about 2 years under heavy use, then the temps started running super high. spent hours cleaning it to put paste on and all is well again.
Just a small suggestion,
Make a metal paste and surround it with silicon paste, so it does not spill off.
Will there be a problem here?
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.
Well, no, it is meant to. What's 100% is what it is supposed to do, and partially by the means of displacing air to have maximum conduction is a less misleading way to say it.
@@Jordan-rb28 The word "partially" is very misleading there. What I'm trying to get across is that there is a balance between heat conductivity and ability to fill in voids. Modern thermal paste sacrifices heavily in the heat conductivity department to be extremely good at filling voids. Since, if heat conductivity was all we cared about, we'd just use the IHS and the cold plate. But we care a lot about filling voids, so we use silicone based compounds which have heat capacities a lot more similar to silicone than to metal.
@@Jordan-rb28not partially, it's entire existence is to fill the gaps between things that get hot and the things that cool the hot things
Its kind of a semantical argument but you have a point. Thermal paste kinda acts like a bridge, but its own thermal transfer is important, of course. Ideally if the cooler and the IHS have ZERO gap (air) between them it would be better than liquid metal because of direct transfer, but its practically impossible, especially at scale.
@@dracopug it's not semantic, you can have all the conductivity in the world, but if it doesn't make contact with the other surface then it won't be transferred.
...did this mf just say to put a piece of plastic around my CPU?

DEHHH CPU CONDOM DEHHH
As a someone who is building computers for almost 20 years, I 100% agree. Just by a proper cooler with flat surface and use normal paste. Liquid metal makes difference only when cooler or CPU is not flat and it has bad contact.
The best thing ever would be if producers of CPUs and coolers were able to make it perfectly flat and you would use no paste.
It also seems to be REALLY easy to install, making building a PC even easier
Correction: Thermal paste is used between the heat spreader and the cooler.
Thermal paste? Real homies use toothpaste.
I saw a test somewhere that showed toothpaste producing quite positive immediate results, but there were some doubts that it would last as long as traditional thermal paste, as it was expected that the toothpaste would dry out quickly and potentially generate voids.
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
Future of thermal technology: Thermal Grizzly Kryosheet
IDK if that helps? It's like putting another metal layer on the CPU, and then you have the plastic on this.
If someone as silly as you cuts the plastic and then mount the PC horizontally, the metal would fell off.
I believe it shouldn't be cut, rather the metal should be covered in plastic. In this case, we're back to the initial issue - it's like just putting a plastic on the CPU itself, which is metal. Why do you need another layer!
Also, the main purpose of the heatsink is to fill the gaps so that there's more contact area. The silicone based solution isn't great, but this solution isn't also going to be great either.

@@Unethical.Dodgsonbeeswax
@Unethical.Dodgson mix lithium and sodium together, and you get a nice liquid metal alloy just dont take it swimming
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.
i think most people use silver paste because of this
Gallium doesn't corrode aluminum.
It combines with the aluminum to create a very brittle alloy.
The oxide layer actually prevents gallium from doing so as easily.
🤓
You can protect neighboring components from liquid metal contact with kapton tape or clear nail polish.
Gallium destroys aluminum by forming an alloy with it.
Bro was so quick, he forgot to finish the sentence.
Man, I waited for him to squeeze the metal
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.
...isn't that litterally the same?
A) there is air connecting the 2
B) there is thermal paste connecting the 2
To make that worth it, it needs to conduct heat better than air.. so yeah, the goal is still heat transfer?
@@tigerboy4705 no the goal is removing air pockets, if we could manufacture perfectly flat surfaces (which we can't) then there wouldn't be a need to have thermal paste assuming you mount your cooler perfectly level.
@@tigerboy4705yes
@@tigerboy4705
The difference is in thermal conductivity. Air is a poor conductor of heat when stagnant and thus an excellent insulator. The insulation in the walls of your house works mainly by trapping pockets of air in the fiberglass. The reason air doesn't transfer heat well is due to less molecules being present to interact with the hot surface. This can be improved by forced convection which increases the amount of molecules interacting with the hot surface. If forced convection is done at such a speed that the airflow is laminar, heat transfer is marginally improved. If airflow is turbulent, heat transfer will be drastically improved. Surface area also plays a role, increasing the amount of molecules on the hot surface which may absorb heat and interact with air for cooling.
Now I want to calculate the minimum air speed necessary to cool a CPU with no heatsink 😭
@@SnipDillard You've done something to my ADHD and now I wanna full blown research this.
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
That’s why most head spreaders are spring loaded and not mounted purely based off the tension the bolt/screws provide. It allows for thermal expansion as well as the softening of any paste you apply.
The same thing you’re talking about happens with regular thermal paste too. It’ll get a lot more runny when it’s hot.
theres some tension on the cpu from the cooler which would account for that when up to temperature
I think people have definitely forgotten why thermal paste was created. It was never meant to be a whole layer of thermal conductivity. It was meant to fill the tiny gaps between two metals for improved thermal conductivity between the processor and heatsink. The metal to metal contact between processor and heatsink is still the best solution.
If you were to polish CPU and heatsink to a mirror shine with no gaps you would not need thermal paste.
Just spray the motherboard (around the CPU socket) with transparent film.
Now if you spill liquid metal you can just wipe it away, and it's also waterproof against condensation for those who want to experiment with liquid nitrogen cooling

Use the silicone on the outside to stop liquid metal from running outwards.
It will just push its way through the thermal paste there is a video of someone testing it that way
Just dont use too much...
Then the hot liquid metal will touch the cooled silicon. The silicon will heat up and eventually melt letting the metal through.
@@fatalz3276No, silicone can deal with temperature over double that of what a CPU is even able to reach before it throttles.
Bro removed all bass and made the trebble as high as possible on his mic

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.
Are you saying this actually works with aluminum heatsinks? That's actually quite the innovation
An issue you overlooked with liquid metal is that they tend to be highly reactive with other common metals, chief among them aluminum.
Gallium and mercury will devour aluminum, be mindful were you apply it if you decide to, as some CPUs may be plated with aluminum.
you won't ever catch me with a piece of plastic on the cpu
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.
Been using their graphene pads for a few months now and it works. No more messes or worrying about liquid metal on parts.
Yeah, what about temperature?
@@VITAS874 your kidding right? you can use graphite pulled from batteries to built a mini arcsmelter to melt down steel. ttemp is not a problem.
@@sorejack with grizzly it is.
What is the music in the background ??
YESSS I WANNA KNOWWW TOOOOOOO
1. Plastic will keep the heat on the chip, instead of dissipating it.
2. Heat will hence multiply.
3. While getting hotter, the metal will liquify.
4. The hot liquid metal will make the plastic melt.
5. The melted plastic will no more retain the liquid metal to run on the motherboard.
6. End of your computer.
You still need to change the heatsink or at the minimum check it every once in awhile as it will destroy it over time. So I may help it stay on the CPU it doesn't solve the other issues
Boron Nitride conducts heat like Diamond and doesn't conduct electricity
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.
thats a pain in the butt
@@Toxic2Twhere?
@@Islykidsthe butt
11yrs now and didnt change LM, simply no need, temps remained the same more or less. Air cooled cpu so if it gets a bit more dusty, temps rise few C up, after cleaning all back in normal. Sure its risky, but i think if u dont plan to change cpu at any time soon, its worth more then swapping regularly for the regular
They don't want to pay SONY to use their sponge solution 😂
If you collect enough, you can cast a spoon. And let coworkers stir their coffee.
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.
thanks of the tip and explanation!
this is wildly incorrect lmao good troll
BS
@@zxphvr He's not wrong... but he's still not necessarily correct.
The best heat transfer occurs where the lowest distance between component and heatsink exists. Some would assume that this means the areas where the component is in direct contact.
This isn't necessarily true. The paste acts as a mediator between component and heatsink because transfer of heat between materials of differing material and density is not a straight gradient.
The paste also has the added benefit of smoothing out any non uniform areas of components, though. So he's on the right track.
Not Wildly incorrect... but not really right. Of course the specific heat capacity of the materials involved plays a role but most people don't give a shit about that. They just want to know: "Will this stop my CPU from melting?"
@@Unethical.Dodgson That doesn't really make sense. The thermal paste is usually a mix of silicone and either some ceramic, metal or carbon particles. So it's full of microscopic interfaces between different materials, most of which condict heat much worse than aluminium or copper.
The thermal paste is there to maximize contact area and it should be as little as possible, while being as much as neceessary to fill any gaps.
Brand new PC builders will always mess it up though
Wake me up when metal-based thermal pads are a thing. So it dont drip.
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.
I had a sheep mentality and went with thermal grizzly's kryonaut cuz everyone said its the best. I then repasted a month later with noctua nth2, I didn't see a difference.
Vertically mounted CPUs are laughing right now
For best results; delid your i7 with a box cutter and apply liquid metal directly to the chip...
Liquid metal won't do much between the cooler & heatsink if there is FACTORY THERMAL PASTE between the chip and that heatsink... That's a clogged thermal bottleneck.
Anti-seize it is a paste that has metal in it, it works as good as liquid metal with the control of a paste. And, as it is made for car engines, will not dry out or break down due to the heat.
Love this
A ~10 thou thick sheet of indium metal is a tried-n-true alternative that seems like a better alternative. Indium is soft enough so as to conform to the surface inperfections of the two faces, and creates an almost perfect, fully metalic interface, with no risk of liquid metal damage.
And indium has an 86 W/mK thermal conductivity, higher than either of these a decent margin.
It’s expensive and requires a really high mounting pressure to work properly. Higher than most consumer grade electronics can handle.
We used to use indium heat springs in our immersion ready server blades because it wouldn’t be effected by the immersion fluids we used.
We ended up switching to a PCTIM by laird. It’s basically a solid version of your typical thermal paste. It’s solid at room temperature and is sold in really thin sheets with a plastic film that you have to remove from both sides.
Once you apply it to the chip, mount the heatsink, and power the system on, it melts and finishes spreading and filling the voids. It results in a VERY thin and extremely even spread of thermal interface material. It performs extremely close to liquid metal tim, without any of the risks involved.
Pretty neat stuff. I’m surprised it hasn’t gained popularity in the consumer market. It’s super cheap, super easy to apply too, no more guessing if you put too much or too little. Simply measure your chip, subtract 20% off the length and width and cut your sheet to that size. Center it on the chip and apply your heatsink. It will spread to fill the remaining 20% that you subtracted from the size of the die, every single time.
Yeah that stuff is great! I've even seen it as "liquid metal" version (InGa alloy probably) which gets applied as a thin sheet and melts into place.
Can I just say it’s awesome to see people talking about such highly technical stuff in the comments. I wish to be as smart as u guys one day.
Indium is also insanely expensive.
You could put the thermal paste in a square as the outline and inside the metal one
I still using the old white ceramic termal paste without problems, cheap and good
Petition for mryeester to use solder as thermal paste
👇
I have used this stuff and it is fantastic. Absolutely the best way to go to keep good temps and nothing matches its performance
Bull shit
This looks great in theory, but it'd be a real pain in the butt if you wanted to change coolers or the processor itself because you'd have to heat it up or do it right after you turn the system off because if not, it would almost be like the cooler was soldered onto the CPU
Seems practical enough
It's not the motherboard people are worried about. It's the cpu
These days enthusiast grade motherboards are literally more expensive than the CPU's themselves. And there ain't no way anyone is using liquid metal unless they're doing custom water cooling with some extensive overclocking and you would definitely want a high end motherboard for that.
@@AngryDraconequus1 ppl on a budget don't care about a top of the line motherboard I bought a shitty 80€ motherboard I don't even know the name of and got my R5 5600x for 300 when it released, my pc never had any issues because everything is stable and well put together.
It may not be relevant, but getting liquid metal on your mb can kill your CPU depending on what shorts, they're intrinsically connected once installed.
Ehhh no. Your motherboard is at risk just as much as your cpu is when using liquid metal. Even your gpu is at risk if you don’t know what you’re doing and apply too much.
people on a budget wouldnt even consider using liquid metal lol, whats your point?@@zydeox1221
Nice
It took to companies this long to figure out that gallium exists
Love how innovative and open minded everyone is in these comments, and when someone actually makes an upgrade that works they'll forget all about the in between steps of experimenting and testing and just start praising them, truly shows how lazy everyone is now-a-days, thankfully we still have curious people willing to experiment furthermore, just remember y'all, you wouldn't be playing your games if blue LED's weren't discovered, a thing that took a LOT of experimentation and investment to make, we owe our technological advancements to these types of people so instead of putting them down try to be respectful
