Thermal Grizzly KryoSheet (38x38x0.2mm) – Ultra High Thermal Conductivity Graphene Thermal Pad – Perfect Alternative for Thermal Paste on CPU/GPU/PS4/PS5/Xbox – Made in Sweden

I picked up the Thermal Grizzly KryoSheet for my AMD Ryzen 9950X3D, and I’m genuinely impressed with the results. This CPU is no slouch, especially under multi-core workloads, and I was looking for a clean, high-performance thermal interface that didn’t involve reapplying paste every few months. The KryoSheet has delivered.After installation, idle temps were stable at around 46C, and load temps hovering around 55C with my AIO cooler. More importantly, sustained loads during gaming and rendering show a noticeable improvement than previous thermal paste products - which is especially important for the 9950X3D’s 3D V-Cache, which can heat up quickly.One word of caution: this pad is thin and very delicate. You will need to handle it with precision! It's also electrically conductive, so make sure it’s perfectly aligned on the IHS to avoid shorts. I recommend doing a dry fit before final placement.For those with a high-end Ryzen CPU like the 9950X3D, the KryoSheet is a solid, mess-free thermal solution—just be ready to install it carefully. However, it's definitely worth the price, and I never have to worry about it drying out for the life of the CPU and cooler.

This sheet cooled down my Ryzen 9 9950X3D processor compared to conventional thermal paste. I think it’s because it makes a more complete contact with the CPU and never pumps out. I’ve used lots of high quality thermal pastes like Kryonaut, TFX, and even Noctua’s signature blend. This Kyrosheet kept me the coolest, and it can be reused without any cleanup. Win/win.

First off this was easy to install, albeit you must be careful!Do not bend any edges and don't place it on any capacitors or transistors! The 38x38mm fit over my Intel i9-12900k and the CPU temps look great! I first installed one of these on my older i7-8700k CPU when I noticed high temperature during Throne and Liberty, and this pad dropped the temps while playing that game by a solid 10C which was wild! I had also de-lidded that particular i7 and applied liquid metal between the chip and the IHS prior but was still getting crazy temps while playing that game, but not anymore thanks to this item!(My thermal paste must have also been pretty old tbh)

Thermal Grizzly KryoSheet Really dropped my temps to 47 Celsius of my Intel i7 14700K CPU at idle in windows 11 it Bios it dropped to 29 Celsius. It was very easy to install I recommend wearing gloves when installing. I highly recommended this brand and product to lower temperatures

We used this product to replace thermal paste that we suspected had dried out (turned out it wasn't covering the whole chip very well either). As expected, this pad was very thin and fragile (it cracked once as we tried to install it) but it was hard to put in because nothing was holding it in place as we reattached the CPU cooler over it. Wish they'd made it sticky on one side, since that would have helped a lot. Took about a dozen tries before we got it secured properly, but it seems to have fixed the original overheating problem very well. Recommended with caveats.

Maybe 1 star is too harsh, but it very much matches my experience with the product.I absolutely hate dealing with thermal paste, so I thought that Grizzly's KryoSheet sounded like a great idea. You just place the sheet on the CPU and don't have to deal with any goopy paste or worry about whether you got the right amount on there. However, it turns out that it's far, far, far harder to use than thermal paste.You're supposed to place it on the CPU with about a 1mm of space around the edges, which is pretty hard to do, since it's trivial for it to shift too much to one side or the other, but in spite of the difficulty, I was able to get it placed on the CPU properly. What makes it insanely difficult though is getting the heat sink on without the sheet moving, and I simply couldn't do it. It probably would have been easier had I used the stock cooler, since with the Noctua cooler I was using, you had to screw it in from the bottom, but either way, it was just too hard. The sheet _desperately_ needs the ability to stick to the CPU and/or heat sink. That's probably not chemically possible without making it not work properly, but placing a dry sheet that the slightest shift of the computer or bit of air moving causes to move is just too hard - let alone when you're trying to place a heat sink down on top of it.As such, I cannot even vaguely recommend this product. It's quite possible that it's utterly amazing if you can get it to work, but IMHO, the only way that it makes any sense is if you're willing to waste the money that it costs to just to give it a try. And if you're willing to take the risk of wasting money on a KryoSheet, be ready with some thermal paste so that you can still put your computer together when you're unable to get the KryoSheet to work. On the bright side, at least the fact that the KryoSheet is dry means that you have no cleanup after failing to place it, and you can quickly switch to using thermal paste instead.
