Thermal Grizzly KryoSheet (33x33x0.2mm) – Ultra High Thermal Conductivity Graphene Thermal Pad – Perfect Alternative for Thermal Paste on CPU/GPU/PS4/PS5/Xbox – Made in Sweden

From my perspective, this is more or less a thermal paste replacement; after applying, at idle, my temperatures are more or less the same as when I was using thermal paste.Under load, it's hard to say as I can't remember the rough temps on paste but things are generally hovering around 60-70c depending on the workload which for me, is usually gaming with the occasional rendering workload.That all being said, it'll be nice to not have to disassemble my system every few months for a fresh thermal paste application.It's easy enough to setup, I'd recommend having a pair of tweezers and laying your motherboard on it's side if possible, then placing your cooler on top. If its not possible, I've seen people recommend to apply just a tiny bit of thermal paste to help the pad stick onto your IHS.

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.

I honestly do not understand why these kryosheets are not raved about in tech blogs or heat reduction forum Q & As. I replaced the thermal paste in my razor blade 15 (i9-12900H and RTX 3080 TI) and wow. Went from nearly thermal throtteling on basically (you could cook an egg on this thing) any game to about a 12-15 degree redux and no more thermal throtteling (no more fingers being scorched..lol) on CPU and GPU runs 15-20 degrees cooler. Amazing, simply amazing and I have been building PCs and working on laptops for over 20 years. Well done Grizzly, well done!

Works as advertised. Highly recommend you use a set of tweezers to apply it as it's very thin. I installed this on a ryzen 9800x3d on an MSI AIO cooler and I get around 35c temperatures which is comparable to using a thermal compound. Would buy this product again to avoid messing with messy thermal compound.

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.

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.

I've purchased some less than ideal products at Amazon over the years, but this might single-handidly be the worst product I've ever bought in my life. It's that bad. First off, I bought one that was supposed to be sized for my specific cpu socket, yet it wasn't the right size so I had to trim it. What's the point of their sizing method if they don't come as the correct size? How hard is it to make them so they don't have to be cut? Immediately after trimming it, mine tore into 2 pieces. I then decided to install it anyways after cutting it to the correct size (which should have been done by Thermal Grizzly in the first place), and my temps are no better than using thermal paste. I had to lay my rig on it's side because these things have no adhesion, so you have to make sure you CPU is horizontal to the ground or this thing will slide right off. I got it all installed and crossed my fingers and the temps are not great at all. I'm going to be throwing this thing away and going back to paste. Extremely disappointed would be an understatement. I will never buy this again and will likely not buy anything from this company again. Do yourself a favor and skip this.
