Graphene reaches its highest thermal (and electrical) conductivity across the plane the carbon atoms are layered. In this application, you are only using a fraction of this material's capabilities
Leon Wolff it would be better off with a larger surface and combine with thermal paste in my opinion, that way the distribution of heat can be more effective for the cooling tower to manage
@Thunder Life it's material, the structure only transmits in one direction If you wanted to make it vertical, it would not hold its structure, and you would have to add a binder to keep them aligned, removing the heat transfer benefit
@Thunder Life It is due to the nanostructure of the material itself. The transport properties in plane are much better because the waves (electrons, phonons, etc) travel more easily between the carbons atoms (through the valence bonds). There is some vacuum in the z direction (out of plane) between the different graphene sheet (which are forming graphite). Those are only maintained together with VdW interactions. The transport properties in this direction are therefore less interesting (by several order of magnitude). Physical engineering student here
_Segue_ which means smooth transition. _Segway_ is a transporter pronounced the same way to allude to the word segue to imply that its a smooth transporter.
We actually use this in Central offices. We will have panels running 40KM SFP's (Long range fiber optic lasers) and we use these to spread the heat across a mass heatsink that then gets bucks of air blown through them. it increases laser life so much. an SFP that would need replacement within 5 years would last 15.

A air CPU cooler works by having the heat pipes move the heat away from the CPU, and then the heat is spread along the fins of the cooler, which are cooled by the air moving over them.

This also depends on how good the interface material between the fins and the heat pipes is, as if that's the limiting factor then more heat pipes is the only answer.
Well, the issue is that you cant just solder graphite or graphene, to any heatpipe, like you can to with aluminium and copper, with a special solder. So it wouldn't have a proppper heat transfer anyway
The reason a lot of heatpipes are copper and the fins are aluminum is because while copper conducts heat more easily, aluminum radiates heat more easily into the air. These pads may be able to spread the heat out along a fin, but if it can't radiate the heat into the air, it'd be useless.

You know those gauge blocks you can use to measure things, where you have to slide them together and they basically stick to each other by a lack of air between them? What if you did that.
Graphenes are good when it comes to their in-plane conduction, but not so much in the out-of-plane direction. So, I'd think that it will do exceptionally good to spread the heat where heat pipes are a non-option.
The biggest problem with it would be the fact that graphene is a great thermal conductor along the plane of each carbon layer, however the thermal conductivity between those layers is poor.

The problem with this is that it only conducts heat really well in the x & y planes, not the z plane. It'd be really good for spreading heat out, but not for conducting it into another object above it. One thought I had was direct-die cooling with a waterblock, where this pad was on the waterblock and you used liquid metal between the direct CPU die and the thermal pad on the waterblock. liquid metal would do it's job to get heat away from the CPU, and the pad would act as a big-ass, super-thin IHS strapped to the waterblock.
Greetings. th-cam.com/video/gNRnrn5DE58/w-d-xo.html I had this nice video in my recommendeds earlier today.

8:21 I just had a flashback to raiding in World of Warcraft. We were doing heroic Cho'gall progression in Bastion of Twilight. We had wiped... I don't know how many times. And as we're rezzing and buffing, the raid leader says, "So... in reality, what we NEED to do is... I don't fucking know..."
When Linus said "can I do a 360" I thought "there's no way he can do that, they are gonna edit that or something" and then baaaam he does it, fucking amazing, what a display of skills, a true legend!
I have an HP pavilion 5030 from 1995. It was HPs first Multimedia PC. It is running a Pentium 75Mhz. It has a carbon heat pad between the CPU and the Heatsink. Years ahead of the curve. It does handle an overclock to 90Mhz with no fan, so there is something to carbon pads.
I think they already did that. Although that was powdered diamond. Riley did it I think. The video was different things as thermal compound. Can't remember the name. They even used a toothpaste.....
Linus: "[dual tower coolers] are so unwieldy" Alex: "But that's, like, part of the appeal tho..." Me, looking at the D15 cooling my Ryzen 5 2600X: "someone had to say it"
Have you guys considered using both at the same time? My hypothesis is that the liquid molecules can, because of their fluidity, go into the small imperfections on the CPU's integrated heat spreader; and the imperfections into the CPU coolings solutions contact area. So if you use a small amount of the liquid on the CPU, and put the PGS on top of it, and then put a small amount of the liquid over the sheet, and then mount the cooling solution on top of it. This seems like its worth trying.
Get the version without adhesive, ive had it on my 2950X for over a year and it is overclocked to the max and doesn't go over 72C, it also really really helps to have a flat surface, this pad is thermally conductive on the horizontal plane more than the Z plane.
What people need to understand is: Why do we need something between the dissipator and the CPU? It is to "fill" the imperfection on both surfaces. You don't fill imperfections on a solid surface.... with another solid.
Well, you could, if it can deform enough under pressure, e.g. a soft metal foil with heavy screw pressure could make contact with the edges of a convex surface or center of a concave one, which is really the more important part. And some larger cavities could also be filled that way
Time to test out PTM 7950 from Honeywell. It is the best according to a lot of users out there. Of course, their testing isn't as clean as what you always do.
rawpie Comparing any desktop component to any laptop component is dumb tbh. My 970m gets to 95 degrees. But it’s also a laptop. Desktop cards aren’t supposed to get anywhere near that ever, plus they’re way bigger and are in a giant open box basically where air can circulate.
Graphite sheet has two types of conductivity, horizontal / vertical. Of course it is in datasheet, but Linus would never say in the beginning. Because you know why.
@@РусяОгризок because there would be no video. It's a physical property. It's a fun video, but with sufficient information it was absolutely arbitrary.
It's called anisotropic heat conduction. Basically, because of the microscopic structure of layered graphite, the carbon rings have véry good conduction to their neighbouring, networked carbon rings. Alas the inter-layer conductivity is quite poor, because there is some sort of (electron) vacuum in between subsequent layers. So basically, we create giant networked sheets of carbon rings, that are tightly coupled. These tight couplings conduct heat very well. But inter-carbon-network conductivity when stacked upon each other is very poor.
Interestingly, this would be solved by using diamond instead, because diamond does have vertical interlinking between the carbon atoms aswell, e.g. i.stack.imgur.com/zytVR.jpg . Sadly, this is practically not really feasible.
hey Linus, since this pad conducts the heat laterally, I think it might work much better if you will stick it to the cpu and then, use some thermal compound on top of it, so that the generated heat will be transferred laterally very quickly
The craftmanship and elegance with which Linus applied the pad to the heat sink, i wonder the CPU didn't shut down immediately. It looks like a friken moon crater landscape ....
Linus: “This Thermal compound can cool with 1950W/m*k!” Me: I wanna buy that!! But might be too expensive! Website: Here is another episode of “I can buy the sh*t Linus shows”
we actually use graphite tape as a thermal transfer in glass blowing. Cept its cut into a roll like tape. i tear a bit off and use it to keep temps the same between to pieces of glass that are touching but not meant to be melted together.
I sometimes think if one of the manufacturers would release a CPU with surface integrated with a radiator base ,which would rid the need of a thermal conductor. It would mean that you couldn't replace the cooler ,but if they make it top-tier(probably for a flagship ,as that would justify their expense) ,you wouldn't need to.
No matter how conductive it is it won’t increase cooling compared to not having an extra layer present. The purpose of thermal paste/pads is to fill the gaps between two separate metal objects, like the IHS and the cooler.
@@CoconutMigrating I'm thinking more for moving heat throughout the fins. That's similar to the idea of using it to move heat on the nose cone of space ships on reentry. not to increase the dissipation. The concept being airflow not hitting all areas on fins equally.
Many people forgot that the main goal of using the thermal paste - removing the air from the gap between cpu and cooler. Air is a good thermal insulator. So thin pads would work if only you make the surfaces ideal. [sorry for my bad english]
Panasonic make a soft PGS graphite pad 0.2mm thick that has a thermal conductivity of 28W/m-K in the Z direction suitable for a CPU, would be interesting to see a follow up using a material actually designed for this purpose.
Well after a bit of a hectic search, the image is from shutterstock by a contributor known as Chuyuss, in a gallery centered around China. The image itself is tagged nuclear, notably the only one out of several other Powerplants they have images of. Only one where the location isn't marked either... not sure if there's a connection there.
Wouldn't even consider this for cooling electronics, but did use this as a Tim for mounting a heatsink on an large bore AR barrel (this allows for longer periods of sustained fire, as excessive heat will cause malfunctions or even catastrophic failure). Thermal epoxy was used to fill the gaps on the sink/radiator side, and this makes for an extremely durable and heat tolerant Tim, especially suited to applications where longevity matters far more than thermal conductivity. It does become single-use at that point though. The barrel radiator/sink in reference here is the "Thermal Dissipator" from JP Enterprises, for those curious.
Same. I remember thinking about my own PC's thermal paste and thinking "wow, so it won't get old!", considering doing it for convenience since thermal paste kinda scares me due to my inexperience with it. How time flies.
Wait! so there at 9:02 ... you rubbed your (natural I assume) greasy finger over a highly thermally conductive material and assumed your tests would be accurate?

Tbh I'm surprised nobody has tried lapping the IHS and cooler face and soldering the cooler to the IHS.
Not surprising it has similar thermal conductivity as diamond since they're both near perfect carbon crystals

@@bobbyflay4104 I thought it was Segway lmaooooooooooooo
And now a bunch of you are talking about the sponsor segue. The plan is working.
Graphenes are good when it comes to their in-plane conduction, but not so much in the out-of-plane direction. So, I'd think that it will do exceptionally good to spread the heat where heat pipes are a non-option.
The real Question: What happens when Linus drops it?
Very very slowly fall or float lol
It's linus proof, the creator made it so that it would gently float to the floor.

This Video: We paid $40 dollars for this?
I think he was mad at how little it cost :D
since the problem is probably the contact surface being uneven
...
you could put some thermal paste on it to bridge the gap
wait.
The biggest problem with it would be the fact that graphene is a great thermal conductor along the plane of each carbon layer, however the thermal conductivity between those layers is poor.
This would actually be a cool concept to test, since we know that the die actually heats unevenly.

"I like how its just, 'Here's the plan,' and then nothing"
Next attempt: Lap the IHS and the cooler to make sure they're perfectly flat.
The problem with this is that it only conducts heat really well in the x & y planes, not the z plane. It'd be really good for spreading heat out, but not for conducting it into another object above it.
One thought I had was direct-die cooling with a waterblock, where this pad was on the waterblock and you used liquid metal between the direct CPU die and the thermal pad on the waterblock. liquid metal would do it's job to get heat away from the CPU, and the pad would act as a big-ass, super-thin IHS strapped to the waterblock.

You missed the opportunity to say that it is "Running in the '90s"
I have an HP pavilion 5030 from 1995. It was HPs first Multimedia PC. It is running a Pentium 75Mhz. It has a carbon heat pad between the CPU and the Heatsink. Years ahead of the curve. It does handle an overclock to 90Mhz with no fan, so there is something to carbon pads.

A diamond you say 🤔 I request a ltt video where y’all cut a diamond sheet and used it as a thermal stone
I think they already did that. Although that was powdered diamond. Riley did it I think. The video was different things as thermal compound. Can't remember the name. They even used a toothpaste.....
they explained that it needs to fill the little gaps
the hole point of a thermal compound is to be fluid
@@ananyaig twice actually.... they also tested thermal epoxy from Tech Ingredients which is also a blend of micro diamond and other materials.

Meanwhile, i look at my clunky D14, thinking of the two Delta PFR's that were in there once upon a time.... Clunky is better?
Have you guys considered using both at the same time? My hypothesis is that the liquid molecules can, because of their fluidity, go into the small imperfections on the CPU's integrated heat spreader; and the imperfections into the CPU coolings solutions contact area. So if you use a small amount of the liquid on the CPU, and put the PGS on top of it, and then put a small amount of the liquid over the sheet, and then mount the cooling solution on top of it. This seems like its worth trying.
the paste shreds apart the sheet.

Get the version without adhesive, ive had it on my 2950X for over a year and it is overclocked to the max and doesn't go over 72C, it also really really helps to have a flat surface, this pad is thermally conductive on the horizontal plane more than the Z plane.
Hi. Which product number are you using?
What people need to understand is: Why do we need something between the dissipator and the CPU?
It is to "fill" the imperfection on both surfaces.
You don't fill imperfections on a solid surface.... with another solid.
Well, you could, if it can deform enough under pressure, e.g. a soft metal foil with heavy screw pressure could make contact with the edges of a convex surface or center of a concave one, which is really the more important part. And some larger cavities could also be filled that way
5:38 "Loose and probably weird. That sounds about right!"

Comparing any desktop component to any laptop component is dumb tbh. My 970m gets to 95 degrees. But it’s also a laptop. Desktop cards aren’t supposed to get anywhere near that ever, plus they’re way bigger and are in a giant open box basically where air can circulate.

Graphite sheet has two types of conductivity, horizontal / vertical.
Of course it is in datasheet, but Linus would never say in the beginning.
Because you know why.
could u explain?i can't even think of any reason not to say this
@@РусяОгризок to clickbait
@@РусяОгризок because there would be no video. It's a physical property. It's a fun video, but with sufficient information it was absolutely arbitrary.
It's called anisotropic heat conduction. Basically, because of the microscopic structure of layered graphite, the carbon rings have véry good conduction to their neighbouring, networked carbon rings. Alas the inter-layer conductivity is quite poor, because there is some sort of (electron) vacuum in between subsequent layers. So basically, we create giant networked sheets of carbon rings, that are tightly coupled. These tight couplings conduct heat very well. But inter-carbon-network conductivity when stacked upon each other is very poor.
Interestingly, this would be solved by using diamond instead, because diamond does have vertical interlinking between the carbon atoms aswell, e.g. i.stack.imgur.com/zytVR.jpg . Sadly, this is practically not really feasible.
hey Linus, since this pad conducts the heat laterally, I think it might work much better if you will stick it to the cpu and then, use some thermal compound on top of it, so that the generated heat will be transferred laterally very quickly
The craftmanship and elegance with which Linus applied the pad to the heat sink, i wonder the CPU didn't shut down immediately. It looks like a friken moon crater landscape ....
Linus: “This Thermal compound can cool with 1950W/m*k!”
Me: I wanna buy that!! But might be too expensive!

we actually use graphite tape as a thermal transfer in glass blowing. Cept its cut into a roll like tape. i tear a bit off and use it to keep temps the same between to pieces of glass that are touching but not meant to be melted together.
I sometimes think if one of the manufacturers would release a CPU with surface integrated with a radiator base ,which would rid the need of a thermal conductor.
It would mean that you couldn't replace the cooler ,but if they make it top-tier(probably for a flagship ,as that would justify their expense) ,you wouldn't need to.

@@Mark_badas many decisions in life you can't be hesitant about, you can't always assume you are wrong.
Linus tech tips. The only channel where I watch the sponsor stuff because the segway is so good
Why not try to use this stuff on the grill/fins of your cooler? That's much more in-line with the intended use case and could enhance cooling.
No matter how conductive it is it won’t increase cooling compared to not having an extra layer present. The purpose of thermal paste/pads is to fill the gaps between two separate metal objects, like the IHS and the cooler.
@@CoconutMigrating I'm thinking more for moving heat throughout the fins. That's similar to the idea of using it to move heat on the nose cone of space ships on reentry. not to increase the dissipation. The concept being airflow not hitting all areas on fins equally.
5:08 Daww, look at the beardless baby Linus.
they used to use graphite back in the day. i remember loosening the nuts on my old server processor to find just a graphite pad.
Many people forgot that the main goal of using the thermal paste - removing the air from the gap between cpu and cooler. Air is a good thermal insulator. So thin pads would work if only you make the surfaces ideal.
[sorry for my bad english]
13:15 Aww, man.. i really thought I was gonna get my Very own Linus
Panasonic make a soft PGS graphite pad 0.2mm thick that has a thermal conductivity of 28W/m-K in the Z direction suitable for a CPU, would be interesting to see a follow up using a material actually designed for this purpose.

Oh man, Linus just did 360° trickshot segue!
How about taking a longer sheet and sticking it to both CPU and base of the cooler at the same time and folding it?
That sounds great. Maybe the material brakes if you bend it like that, and that's why they didn't do it.
Wouldn't even consider this for cooling electronics, but did use this as a Tim for mounting a heatsink on an large bore AR barrel (this allows for longer periods of sustained fire, as excessive heat will cause malfunctions or even catastrophic failure). Thermal epoxy was used to fill the gaps on the sink/radiator side, and this makes for an extremely durable and heat tolerant Tim, especially suited to applications where longevity matters far more than thermal conductivity. It does become single-use at that point though. The barrel radiator/sink in reference here is the "Thermal Dissipator" from JP Enterprises, for those curious.
would wanna know if wearing gloves when putting the sheet on makes a difference. Isopropyl alcohol cleaning of the surfaces included.
