KryoSheet (25x25x0.2mm) – High Thermal Conductivity

Earlier this year, my 2020 MSI GE75 Raider (10SFS-226) started running hot—both while gaming and even at idle. I decided it was time for a full deep clean and repaste of the thermal interface materials. Since the system is older and runs unusually hot, I wanted something far more efficient than traditional thermal paste—but without the risks associated with liquid metal. After thorough research, I decided to try Thermal Grizzly KryoSheet, a graphene-based thermal pad designed for ultra-high conductivity and long-term stability. I was excited to test it after hearing that it had been massively improved from the original carbon sheet version. It’s said to perform almost on par with liquid metal, and now I can confirm—that’s absolutely true. The packaging is top-notch: compact, well-designed, and protective. The KryoSheet comes in a separate small box, resting on a soft, pliable mat and sandwiched between two plastic sheets for added protection. Installation tips: Make sure you order the correct size for your CPU and/or GPU die. Avoid cutting, touching, or flexing the sheet—it’s very thin and delicate. Because KryoSheet is electrically conductive, I also used Thermal Grizzly Kapton Insulation Sheets to cover the exposed SMDs around the CPU and GPU, and a small amount of viscous silicone oil to help it stay perfectly in place during installation. Both precautions paid off—the process was smooth and trouble-free. Performance results: Idle temps dropped from 50–60°C to a rock-solid 40–50°C (often holding steady in the low 40s). Under full gaming load, the CPU never exceeds 80°C and the GPU stays below 70°C. Performance is nearly identical to liquid metal, but with lower power draw—about 10 watts less from both CPU and GPU—with zero thermal throttling under sustained load. The only difference I noticed was slightly higher clock speeds when using liquid metal, but given the thermal efficiency here, that’s negligible. The best part? You’ll never have to replace it. KryoSheet doesn’t dry out, pump out, or degrade over time, as long as you leave the heatsink undisturbed. After using PTM7950 previously, I can confidently say KryoSheet outperforms it in every way—temperature, stability, and longevity. This is, without exaggeration, the best investment I’ve ever made in my gaming laptop since buying it in 2020. If you’re serious about cooling performance and long-term reliability, Thermal Grizzly KryoSheet is second to none.

Any reviews complaining about how fragile and easily damaged these pads are from clumsy impatient people who can not be bother to slow down and take their time in order to use it properly. I had no issues handling and applying this pad with no damage and used the method of using the absolute teeniest tiniest little dot of thermal paste on each corner with a light tap in order to keep the pad in place while delicately lowering and screwing down a massive cpu air cooler with zero issue. Take your time, take it slow, and do it right the first. As for performance and ease of use. i can safetly say i will never use thermal paste again as long as i can get these as it surprisingly dropped all of my temps and average temps on a 5950x by around 5c. Not much change on the minimum temps but i am very happy to not have this cpu spike as much into the red and happily remain in the mid 70 to low 80's under heavy load with the benefit of not having a massive mess of paste to clean just to repaste it again if anything is wrong and risk damaging the cpu pins or socket since certain paste's love to act like glue even when the cpu is hot and refuse to let the cpu go which results in you ripping the cpu out of the socket because the paste fused it to the cooler which is just another step to worry about trying to pull them apart without any damage. This pad is a absolute life saver for cleanup as well as reducing temps, even if the temp reduction is not by very much if any for the benefit of not having to use paste or dismantle your system again for quite some time. The instructions also recommend that you really should replace it after use rather than reuse it due to damage from the first initial install and i dont mind that since i will rarely be taking my systems apart, and if i do then i will gladly buy another pad or two when the time comes for me to take it apart, rather than risk any issue. Yes they are pricey but in my opinion they are extremely worth it for those who will rarely remove their cpu cooler for long periods of time and want a simple no mess solution that matches or even outperforms paste (in my case) if your lucky, etc. Highly recommended!

I had the issue of some reference 7900 XTX having high junction temps. I did not take ss of before and after temp, really wish I did now. Playing Darktide used to peg the fans to 98-100% and the junction temp would stay at 108-110C. Replacing the thermal paste with this pad completely solved the problem. It doesn't go passed 90C now. A 20C difference... that is insane. Not only that but the fans no longer stay pegged at 98-100% they run at like max 70-80% now. It's perfect for fixing the hotspot issue with the reference 7900 XTX. If you have a 7900 XTX this works perfectly and the 29 x 25 sheet fits the DIE perfectly. I did not have a problem with putting it on the DIE I simply let it slide off the plastic sheet it comes with onto the die and nudged it as needed with my tweezers. Picking it up with tweezers is no issue either, it is fragile by nature as it has to be to work properly so any unnecessary drag on it while pulling will tear it. Honestly though it is so easy to lay down idk how people are managing to tear this thing....I could maybe see it for a CPU but it's perfect for GPUs and the best part is you never have to worry about repasting. I did end up laying the pad on the cooler itself and then setting the PCB down onto the cooler. Because of how the GPU is taken apart this was the best way. Just cover the raw copper plate with the pad and carefully set down the PCB into position. It is important the pad does not move, both for cooling reasons but also because the pad is conductive, so you don't want it touching the the area around the DIE but only the DIE iteself. It worked first try for me without issue, if you try to leave it on the DIE and then do this it's basically impossible since you have to flip the card over to screw the bracket into place for the PCB and all the other screws. That is why I ended up placing the pad on the cooler and then setting the PCB down on top of it. The plate and DIE obviously line up perfectly so it's no different than placing it on the DIE and then putting the cooler on top of it. TLDR; Had 7900 XTX reference 100C junction issue, pad dropped it 20-30C and the fans run at like 50-80% now under heavy load, not 98-100%

the application was fairly straightforward and it worked well and kept my temps cool during the warmer months when my CPU would normally overheat.But after almost a year of use the heat melted it (didn't liquefy just kinda fused it) to the cooler, so when i tried to remove it for some maintenance the pad crumbled and fell apart. TLDR: worked perfectly until i tried to remove it.

Works well in production environments. I've used these on a number of Dell servers and workstations where the thermal compounds degraded and much to my surprise the performance is the same or better than conventional thermal pastes. I have also successfully reseated the pads and changed processors without degredation of the thermal properties. Handle gently though -- they can break.

I love these things and use them on every new build. I always use larger sizes to make them easier to install. It won't hurt anything to go up a size in my experience if the socket allows it, like for AM5 I use 50x50 and they work great, and sure beats trying to align a smaller one with your cooler. As long as it doesn't touch anything on your motherboard (it's conductive), you're good.

I installed the Thermal Grizzly KryoSheet (33x33x0.2mm) on my AMD Ryzen 9 9950X3D, and the results have been outstanding. Compared to traditional thermal paste, this graphene thermal pad delivers lower temps, faster thermal transfer, and zero mess during installation. It was incredibly easy to apply – just set it in place, mount the cooler, and you’re done. No spreading, no cleanup, and no worrying about reapplication down the road. On my system, I noticed significantly more consistent temps under heavy gaming and productivity loads. The KryoSheet keeps my CPU cooler and stable, which is critical for a processor like the 9950X3D. It’s also reusable, which makes it even more cost-effective long term. If you’re a PC builder or enthusiast looking for the best alternative to thermal paste, this is it. Highly recommend for anyone running high-performance CPUs or GPUs – it’s a game changer!

I bought this twice. For the first one I applied the oil drop that was probably too large and it gripped the sheet dead. It was slightly off-center when I placed it, and as I was trying to shift it using the pieces of transparent foil that it came with, it split along a vertical line, about a fifth of the sheet off. I was still able to jigsaw it together and used it until the replacement came. For replacement I used a much smaller drop, but that barely gripped the sheet. Still, it was well aligned and when I took off the cooler a few days later it was stuck to the cooler really well centered. Now for its performance. The idle temps were unchanged compared to the paste that came with my be quiet Dark Rock Pro 5 cooler. But under load, with the 9950x3d drawing (I estimate) around 140 W I experienced my first thermal cutoff with the computer fully froze and all fans going to 100%. I then experienced it a couple more times, every time within seconds of launching a game that normally uses around 140 W on the CPU. I saw temps above 92C just before the cutoff. After switching to the ECO 105W mode the game worked fine, I saw a load of around 125 W, and temps around 72 C. I am quite perplexed by this. Why would an additional 15 W push the temp up by another 20 C? If there a limit to the max thermal flow with this sheet that is perhaps exceeded? After I replaced the sheet with the thermal paste (Aeronaut that came with the CPU mounting bracket) I saw the expected behavior, the game that draws 140 W made the temperature go to just around 75 C. I also installed the cinebench 2026 and ran that. It draws 200 W when loading all cores and the temp went up to around 82 C or so. So my conclusion is, it's a cool product that looks neat and works well if your CPU takes less than around 130 W. For 9950x3d it will work really well if you run in the ECO mode. Very puzzled by it's behavior - looks like it reaches a thermal flow limit somewhere just above 130 W and then doesn't work well at all. My second sheet also had a gouge out of the box - you can maybe see it in the picture. Not sure if that is a factor. I am quite happy with the paste performance for now, and will leave it as is for a while.

ペラペラの紙に見えるが、これがよく熱を通す。 CPU周りが、汚れない。 ただ、CPUと水枕等の接地が均等ならよく熱を通します。 接地面に隙間が出来るようなら、シリコングリス等が良いかも。

Quite expensive. But worth it, especially that you can re-use it (I assume) and saves you the mess of thermal paste

I have tried a couple of oversize versions of this thermal pad which required cutting to fit. That turned into a disaster each time. The pads simply broke up either when cut with scissors or when slid around to position it on the CPU. They are quite fragile but it was my fault on both occasions. I thought I'd give it one more go with the correct size for my CPU being back in stock. This pad came with a small tube of silicone (the others didn't) that assisted the pad the stay in place when placing it on the CPU. So, no cutting and no worrying about the pad sliding around on the CPU now that it had a drop of silicone to hold it in place. The thermals for the CPU (Ryzen 9950x3D) have dropped 1 degree from the thermal paste that was previously used ie 39 degrees down from 40 degrees while idling. Not a great deal of difference but the fact that I shouldn't have to worry about the thermal grease drying out over time is a bit of a consolation. Expensive when compared to thermal grease but peace of mind will make up for that (hopefully!). At this point I recommend the Thermal Grizzly KryoSheet Graphene Thermal Pad and would use it in the future.

Works like a charm

Absolute worthless. Not 1 degree cooler then my paste that is 10 years old (fresh applied on cpu). So if you have paste don't do it. Waste of money. Yes i did all the steps correct. Wasted 20 euro.
