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 decided to try this out as I was having to replace the thermal paste (Thermal Grizzly Kryonaut) every 3-4 month due to the heat pump effect from the heat cycling of the PC when powered on and off, as the paste got squeezed out temps on the CPU would creep up and it was annoying as heck. Installed this today and immediately got the same or slightly better temps than with the Kryonaut paste, and no more drying out/pumped out paste to worry about! As a side note you do have to be careful cutting this stuff, it's quite brittle in certain directions, you can see that by the grain, so cut along the grain where possible. I had to take a 5mm strip off one edge cause of the width being shorter than the length on Intel 12th gen chips. If you take your time, it's a doddle and I'd say well worth it, should be stable temps now and less maintenance (x fingers). My system runs a 12700k @ 5.4Ghz OC, and an RTX3090 (in a fairly tight case) both of which are water-cooled with EVGA AIO's, but the CPU could get quite hot once the paste started degrading, this so far has sorted that problem, but be careful this stuff is conductive, and will cause shorts if you're not careful about cutting it! As mentioned, it’s quite brittle, so don’t let any shards break off onto the motherboard, you may find the magic smoke makes an appearance when you thought everything was running just fine ;), some comments seem to suggest this has happened to people, so take your time and do it right! Update: 3 Months in, and happy to report, no degradation in temps up to now, great investment. Update: 12 Months on, still getting the same temps as I'd get during summer when using paste, other than hoovering dust off filters on the case I haven't had to take the CPU off at all in that time!, Buying another sheet to do my GPS next ;), wish me luck.

Using this on my Laptop GPU and it is amazing. Temperatures aren't getting above 62C when they used to be high 70's with paste. I couldn't get it working with my laptop CPU because my heatsink doesn't make tight enough contact.

I was really sceptical about whether this could truly improve temperatures, but was amazed to see the results! On an Intel i7 8700, with a Thermalright AXP90-X47 cooler, I was getting idle temperatures of around 40c and loads temps over 80c using a generic paste. These were comparable to the i7's stock cooler. But with the same cooler and KryoSheet, I am seeing idle temps in the low 30's, and full load temps in the low 50's. That's a reduction of over 30 degrees! Given the 8700 is renowned for running hot, and I have it placed inside a tight itx Phantecs case, I am absolutely astounded at these results. For anyone else that uses this, keep in mind it seems to take about 10 minutes to settle under load after first installing it, so don't be disheartened by initial temps (it was idling at around 50 for me to begin with, then the temps dropped right down). I'll definitely be sticking to this in future builds. It's a bit tricky to cut down to size, and you have to be careful when installing the heatsink to avoid it slipping, but zero mess to clean and awesome temps!

It is close to liquid metal(conduct) . The perfomance is impressive and easy to reuse if it is not baked on it. The direct die is perfect and easily to be reuse. The normal block on ihs it was baked on it ,but it was better perfomance than the thermal paste. It is not cheap solution, but easier to apply on it. Iam extreme overclocker. 13900ks on direct die hold on 5.9 ghz p cores all cores and 4.6 ghz on ecores all cores. Remp around 80-90 on the stress test with custom loop 420mm and 360mm rads thick rads.

Was looking for something else to try as thermal paste is very messy this works great Why did you choose this product over others?: As i said i was looking for something else other than thermal paste and cam across this Value for money: its a littlke pricey but in the long run your saving money as it never needs changing Size: It comes in a few sizes for different CPU types Make sure you do a little research to get the right size for your CPU type I got the 38x38 Which is perfect for AM4 Quality: Very good quality does the job well They are quite fragile so be careful Also unlike thermal paste they do conduct electricity so be careful not to drop it on any other part of your motherboard or you could end up with a fried motherboard

Didn't think this would work but has perform quite well so far and does what it is supposed to much better than using paste which I hate using. using it on a AMD RYZEN 7 9800X 3D with a iCUE H150i ELITE LCD XT Display Liquid CPU Cooler and seems to be running sweet.

Slightly less messy to apply than bog standard thermal paste, but still a little fiddly. They are incredibly delicate, mine started to tear slightly during a careful install - not enough to affect it but enough to be wary about the resilience. Perfectly adequate in thermal transfer, on a 9950x3D with an AIO, it maintains 50-70C depending on load - but not really any different to a decent thermal paste. Probably not really worth the cost

good complete product - comes with some insulation tape strips i used to cover capacitors & silicone oil to help secure the pad but i didn't use it. 38x38mm is perfect for AM4. i did what i read in somebody's review i got a dentist mirror to check the positioning after i mounted the cooler, because IT IS ELECTRICALLY CONDUCTIVE. i paired this with a dark rock 5 cooler with 1 fan (i can get a second fan it includes spare clips for it) - i was running Arctic's mx-6 paste & freezer 36 cooler with 2 fans - the temps are better, somebody said it needs time to settle-in, and i've only just done 3 x 20 minute sessions on Battlefield so far and each time the temps were getting even better. the dark rock 5 cooler seems perfect for this graphene thermal pad on AM4 because the contact plate is slightly larger than the CPU, whereas the Arctic freezer is smaller, thus the dark rock fully covers & holds down the thermal pad - i would not use it with smaller contact plates as it may squeeze and fracture the pad along the sides, i guess . . i can breath easy using this because it's non-toxic, whereas paste is highly toxic to aquatic life thus i hate it and it probably means it's toxic to ALL life so, NO ! . . also it's reusable, great, and now it's all setup i probably won't be taking it apart again because it's a zero maintenance product . . (keep the box) Thanks for this !

Excelente opción para disipar el calor de CPUs y mas si no se quiere cambiar nuevamente en unos años. Usaba la Thermal Grizzly Kryonaut pero como tiene un alto indice de Pump-out Effect (al calentarse el CPU y enfriarse en ciclos de uso rapido, la pasta se desplaza desde el centro del IHS hacia los bordes) genera degradación rapida en el efecto de transferencia de calor. Decidí cambiarla por esta solución, lo cual hizo que mis temperaturas bajaran aproximadamente 5°C bajo carga sostenida y en pruebas de estres, lo cual no es mucho pero las temperaturas minimas si disminuyeron aun mas, de 57°C en idle pase a 46°C, ademas la respuesta al cambio de temperatura mejoro.

It didn't lower temps more than, paste, fragile and gets cut easily, but supposedly as long as cooler is there (never removed after installation) it will last longer than paste.

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.

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.
