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.

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.

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.

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.

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.

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.

You know i'd love to know if it works better with a lapped IHS and cooler plate, so you know it is getting solid contact & minimize the distance as much as possible Specially with how terrible the IHS on my 3950x was when i lapped it, i want the thermal pads to work!

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. You'd need to somehow take advantage of its lateral heat transfer.

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

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.

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.

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

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.

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 ....

It's funny going back to this and seeing the classroom test take 6 minutes after having watched your video on that incredible server, which rendered it in ~10 seconds lol.

If you need convection on top of conduction to make something similar to a heat pipe out of it. Could roll and glue till you get a pipe or you could even use 2 sheets sandwiched together water tight, with multiple small capillaries instead of a single channel. You could even make a liquid cooled tower off of it, wouldn't need to run liquid right over the chip if the heat sync were made of this, you could just channel through the tower (which is made of this stuff) and call it a day.

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.

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

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

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.

Whenever somone asks : "Is that even possible?" The answer is always "Yes" while picturing Giorgio A. Tsoukalos

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.

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.

Yeah was that a reference? I thought it to be a bit too random.

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.

Was anyone else jump scared by how quickly linus starts talking? I hadn't even finished clicking the video?

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.

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.

I would be curious as to how this would work if you add a good thermal paste in addition to it, and then compare the difference between this with thermal paste and with thermal paste alone. The problem is that there’s an expectation of thermal transfer when its only touching the top ridges of the CPU’s IHS. Therefore, an intermediary thermal compound would be needed to get into the microscopic gaps of the IHS.
