KryoSheet (38x38x0,2mm) - Graphene Thermal Pad - Highest Thermal Conductivity - Alternative for High Performance Thermal Paste CPU/GPU/PS4/PS5/Xbox

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

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.
