I worked for a competing distributor and Panasonic came to our facility to give us training. In fact the people in the video were actually the ones giving the training. The particular pad you were using is really only designed for lateral thermal transfer not thermal transfer through the sheet. In fact their page specifically lists heat diffusion as the main use for this pad. They have a separate product described as Graphite-PAD is a thermal interface material (TIM) that compatibly obtained excellent thermal conductivity in thickness direction (Z-axis direction). You may want to redo with one of the z axis pads.

@@thunderlifestudios 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.

right? The whole point of a thermal interface material is for void fill with a conductive material, otherwise direct contact with no transfer material would be the best way to transfer heat.

What Linus doesn't know is that, that material doesn't have the same heat transfer in all axis of its chrystal structure. Laterally, it performs great. Close to diamond. But vertically, it performs close to copper (about 1/5th the heat transfer laterally) So, he might as well be using a thin sheet of copper.

What if someone made a CPU cooler with sheets of this stuff on the fins? 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. More heat pipes in a CPU cooler is better because it allows the heat to be more evenly distributed on the fins, since the heat concentrates more on the fins closer to where the heat pipes are. Since these sheets are supposed to transfer heat well, putting them on the fins of a CPU cooler may allow the heat from the heat pipes to spread more evenly along the fins, mimicking the increased cooling of having additional heat pipes. Can someone tell me if I'm theoretically right? Upvote to get Linus to test this.

[@MrStonedOne]

I came here to comment this exact same idea.

[@CockatooDude]

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.

Dude price

[@eduardoavila646]

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

[@Crazyates11]

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.

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.

since the problem is probably the contact surface being uneven ... you could put some thermal paste on it to bridge the gap wait.

[@rowanangelbeck8840]

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.

[@SukoSeiti]

This would actually be a cool concept to test, since we know that the die actually heats unevenly.

[@2MACH]

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.

[@mikehaldi4093]

Just a small note: a neat property of graphene is that it is only electrically conductive in a planar orientation. So if you you put the multimeter leads on either side of the pad, the resistivity would be much higher (electrical conductivity would be much lower). This is why it is used in electronics.

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.

[@ryukenosuke]

This video and the properties of the graphene sheets had my mind thinking of different uses and applications of that product. I think I've recognized how you COULD use it to better the thermals of a CPU. There is only so much contact surface between a CPU and the heat sink above it. The sections connected with the thermal paste is certainly going to be subjected to thermal saturation, where the material will lose thermal capacity at that spot until the thermal energy present dissipates into the surrounding material. We'll use copper as the example. The contact patch of the copper to the CPU can only absorb so much heat while waiting for it to spread to the rest of the copper of the heat sink via heat pipes or just more copper. Now, here's where the graphene could help. You mentioned that the graphene sheets have an uncanny ability to transport thermal energy and spread it out over the distance of the sheet's dimensions very quickly. So, an idea would be to apply it in this format : CPU > thermal compound > graphene > thermal compound > heat sink. The graphene sheet and heat sink contact surface could then, theoretically, be made quite wide (within the supporting boundaries of the CPU case and motherboard components). Let's say that a 2" x 2" CPU is outputting 200W of heat, thus 50W per square inch. If you took that same 2"x2" CPU and used the graphene to spread the heat out to a 4"x4" heat sink contact patch, you'd get like 12.5W per square inch of heat. Therefore, the copper shouldn't reach thermal saturation as easily, and may maintain it's thermal conductivity efficiency better. If you ever decide to return to this product, I'd love to see you experiment with this suggested setup.

[@BladeEXE67]

We used this stuff at work for a customer. The thing is we make styrofoam insulation systems for underfloor heating, so maybe it is better at insulating rather than conducting heat.

[@TrentBurrows]

I played about with these sheets a few years back and they only transfer heat in one plane along the sheet and not through it. Thermal Pyrolytic Graphite (TPG) on the other hand is available in a form that might work though it is very soft and easily damaged. It moves heat ridiculously easily.

[@Alorand]

Yeah that thermal conductivity is highly directional and horizontal along the plane of the sheet of graphite. So it's great at spreading out hotspots.

Next attempt: Lap the IHS and the cooler to make sure they're perfectly flat.

[@Crazyates11]

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.

[@darthjeder]

Greetings. kzbin.info/www/bejne/nX-1n6Wkaql4a5o I had this nice video in my recommendeds earlier today. Maybe it will be a problem to actually mount the perfectly flat heatsink and IHS together the normal way. It looks like gauge blocks have to be kinda slided together. I will definitely try this when my workshop has evolved. :D godspeed

It would be interesting to see if you had it folded over itself into two layers of one complete sheet. It would in theory allow the dispersion of the heat from the die to the cooler as it has a path to take around the sheet rather than trying to have it go through the sheet directly? Probably wouldn't make any difference but sparked my interest.

[@RoboticusMusic]

Apply to both heatsink and CPU...BUT, still apply liquid metal between the pad layers! Also coat the heat sink fins with these pads!

[@jeffclark5206]

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.

The thing is though, is other than not knowing the direction this is designed to conduct (its directional), there’s also still air gaps to deal with since the top of the die isn’t perfectly flat.

I wonder if using it more to spread heat and use a compound on top to get a greater effective surface area for heat transfer would do any better. Having the additional medium would have another heat transfer interface but just something that might be interesting to test.

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]
