KryoSheet 68x51 mm Graphene Thermal Pad CPU GPU

This is a fine product, but there are a few annoying things I'd like to point out. It's main selling point to me was that you don't have to worry about it drying out or TIM pump out. I was using a high end Thermal compound already at the time of installed with Artic MX-4 or 6 I don't remember. I don't think temps on my CPU change much vs that compound and if they did it was only 1 or 2C. But I didn't necessarily buy this for better thermal performance.After over a year of use my temps haven't change much from my initial results. Which is good no dry out obviously. My setup is a 9950X3D + Kryosheet as my TIM and an Asus Ryujin III 360MM AIO and I'm using a Thermalright CPU holder. My average idle temps have stayed +/- 2C of 35c since switching to this exact setup. No complaints at all. Installation of this thing can be a little fiddly. When you put your heatsink (or waterblock) down on top of this, you don't want to move it around much and even then it can cause this Kyrosheet to move. It also is not very rugged meaning you can ruin it if you need to remove your heatsink or waterblock much during installation. Be warned you might get two or three goes before you have ruined the Kryosheet and need to replace it with a new one. Apparently I got it right on the first try as my temps didn't get worse (or really any better) after switching from a paste to this. I never tried this , but it might be possible to avoid the pad shifting when you place the block over it by using a dab of thermal paste at opposite corners of the pad to hold it in place, but I never tried that.

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!

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.

My 5090 was starting to show signs of thermal pump out, and the new HWiFO64 50 series hotspot temperature reading was showing over 100C. Not good! Using this perfectly sized for a 5090 44x37mm graphene pad brought the hotspot down to just 81C. My normal GPU temperature reading is also cooler, and the fans are no longer ramping up to annoying levels. Perfect! Installation was easy enough, but you have to be careful as the graphene sheet is quite delicate (although reusable if you are careful). A few dabs of the provided oil to keep the sheet in place during cooler installation and that task was easy enough. Oh, and the included Kapton tape does need to be used around the GPU die to protect the exposed components from being shorted as this graphene pad is electrically conductive (which isn't a concern for CPUs, as the integrated heat spreader (IHS) protects similar components).

Let me begin by saying I am a pretty experienced PC builder & modder, IV ebeen building & modding PCs for a little over 20 years. I've come to find great quality stuff from shops, businesses, propel, youtubers, you name it. der8auer is legit, a world class overclocker, & knows his stuff. I've been using other Thermal Grizzly stuff, specifically things like Conductonaut liquid metal, Cryonaut thermal paste, & their thermal pads of various sizes (0.5mm, 1mm, 1.5mm, etc) for all kinds of things like replacing thermal pads on my GPU waterblocks & on motherboard chokes, VRMs, & anywhere applicable on a CPU monoblock for watercooling. That's a bit extreme, but that's where Thermal Grizzly stuff sits - in the more extreme category. What got me interested in this was, the fact that it had extremely high thermal capacity - practically as much as their liquid metal - but without the mess & the permanent damage to copper heatsink blocks. This would be theoretically a much simpler, easier solution. I wanted to specifically use this on my Valve Steam Deck to see how low I could get temps. I know it is possible to do liquid metal on the Steam Deck, however it's not the best cantidate, as it has a higher chance of overrun & leakage of TIM to spill out & possibly short something on the board (even if you kapton tape & clear nail polish the heck out of the motherboard). Also, since the heatsink is made of copper, it would eventually react with the liquid metal & you'd have to reapply it regularly every few years - i.e., a pain in the butt lol. ALSO also, the amount of pressure you can put on the heat sink of the Steam Deck is nowhere near as much as what you can do on a PC or other device, so there's a chance that there's not enough pressure to spread the liquid metal around & create a good transfer. Lots of potential problems. This sheet suffers from the last issue I believe - it just is a bit too thin & can't clamp enough pressure down to get proper heat transfer from the die to the heatpipe to the heatsink. When I originally had Thermal Grizzly Kryonaut (or Kingpin KPX) thermal paste installed, temps were really good. On full load of cyberpunk 2077, 98% gpu load & high CPU load, it was about low/mid 60s for both. Fan speed was also in the low 5k rpm range iirc. Very, very acceptable & well performing. However, when I installed the Kryosheet, the temps jumped to mid 50s at idle, high 80s under load, & spiked to 95c when loading into the game. I even got the little red light of thermal warning, something I'd never seen before. Plus, the fan was ramped up to over 7k rpm, & another highly telling fact, was that the air being blown out of the exhaust vent was lukewarm/just above room temperature. Whereas with the Kryonaut/KPX thermal paste, the air coming out the exhaust was very warm. Borderline hot. That's a good sign - that means the heatsink is doing it's job very efficiently, it's transferring the heat from the die to the heat pipe, to the heatsink, then ejecting it out the exhaust. Very hot air blown out means lower temps in the die package. I tried to follow directions as it said, first I cut the sheet just about 1mm oversized on every side to overlap but not run off. Then the second try, I did the same again, but used a little of the included oil/lube/whatever that was included. It's just supposed to help keep the KryoSheet secured in place when you're placing the heatsink back on, but I figured I'd try it anyway. No difference, same temps. I do have my very, very, VERY old Skylake PC that's sitting in parts after I stripped it down for maintenance. It has an EK monoblock for the motherboard, & it always seemed to have issues with proper clamping pressure & tolerances. I delidded my i9 7940X & replaced the IHS with a custom one from RockitCool that was all copper (so even better heat transfer), & replaced the thermal solder with liquid metal. If I can clean out all the radiators & finally put it all back together, I really want to tey the KryoSheet on the PC instead to see if it works any better than a high quality thermal paste, PTM7950, or just go bonkers & try to find a nice Skylake CPU die frame for the motherboard (an Asus Rampage VI Extreme) & just run IHS free direct die cooling. This is where der8auer stuff lives, & in my opinion is better than the arctic silver or noctua or other TIMs. Anyway, very long story short here, the science says the KryoSheet performs practically as well as liquid metal. In real life applications however, you mileage may vary depending on what you're using it for. If it's for a CPU thermal pad between your IHS & heats ink cooler, or if you throw it in your GPU, regular OR waterblock, it could work incredibly well. If you intend to use it for the Steam Deck however, in my opinion & experience, it doesn't work well at all. In fact, it performs quite poorly in this specific instance. You're better off with a high quality thermal paste. That said, I have high confidence I will find a good use case for this stuff, I have yet to come across Thermal Grizzly stuff that isn't very high quality. It is expensive, however. Whether potentially 3-7c or so difference is worth it to you, is...well, up to you lol. I'm a big der8auer & Thermal Grizzly fan, but make sure you know what you're getting yourself into & you're buying what you need for the right job you're doing. The stuff is high quality either way.

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%

I bought this item in used 'like new' condition. The package seemed to include all parts in good condition. I installed the yellow tape, trimmed the thermal pad to size, and opened the oil applicator to apply a drop of oil on the chip. Despite twisting the top off of the applicator only at that moment, the tiny tube was empty. I squeezed as hard as I could, checked the cap I had twisted off, everything I could think of, but their just wasn't any oil in the tube. There was no way for me to reassemble my GPU without this oil to hold the pad in place. I emailed Thermal Grizzly about what happened. They first said to install the pad without the oil, but that is not possible with my GPU. They asked for my purchase details, I provided them. After that, a whole week passed with no updates. I'm assuming they are ghosting me at this point. I understand it was an already opened product, but the oil applicator was factory sealed. This would have happened whether it was a new or 'used' product. Thermal Grizzly could have just quickly shipped out another oil dropper. They also wouldn't mention what specific type of silicon oil it is so that I could just buy it myself elsewhere.

So I've had my phantom gaming asrock 7900xt white edition since January and temps were fine the first month. Noticed that my hotspot started creeping up to like 97c over these past months with gpu at 62c, so slightly over 30 degree difference. Probably not alarming but id figured it was only going to go up. Ended up ordering a 25x25 kyrosheet pad(that size fits the 7900xt die perfectly, didnt use the recommended size for 7900 gpu on here) and now temps dont go past 66c degrees gpu and 81c hot spot during multiple stress test and +15 power limit. In regular gaming hotspot hovers around mid to high 70s(occasional 80 as peak)The hype is real boyz. The only "con" is that you need to be very carefully handling this pad, tweezers are a must after seeing these reviews of people ripping their pads. They also only give you one sheet as well(which imo they should provide more considering how expensive it is). Also installing it on the gpu requires a bit of patience and planning ahead before securely clamping down, as slight unnecessary movement can move the pad out of place. IMO before clamping the cooler back on make sure the holes look like they will immediately line up up so you dont have to shift too much. Plan ahead. Other than that i love it Im actually ordering another set for my 5950x to see how well it works or improve Edit: So i will say for CPUs you are better off saving money and getting thermal paste. My temps if anything i think are higher by like a degree or 2 for my 5950x, and best case its the same from my old thermal paste. The only benefit of using this on a cpu is there isnt a mess if you are going to open up your air cooler. Otherwise i would say kyrosheet is amazing for gpus and lackluster for cpus

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.

Absolut perfekte Kühlleistung, altert nicht, fließt nicht raus, hat Hotspots auf der CPU etwas gesenkt. Bewirkt keine Wunder, aber die Wirkung war für mich bombastisch. Gerade die Hotspots zu senken war für meinen Anwendungsfall, ein Thinkpad P51 Notebook zu kühlen, entscheidend, denn das ist immer bauartbedingt an der Höchsttemperatur, und die horizontale Wärmeleitung der Kohlefaser ist hier drastisch - ich meine drastisch - höher als jede andere Kühlmethode und dadurch drosselt die CPU wesentlich später und seltener, weil die Spitzentemperatur des heißesten Cores leicht absinkt

He probado este pad térmico en mi MINISFORUM BD795i SE con el potente Ryzen 9 7945HX y ha sido toda una pasada. Durante meses habia tenido ciertos problemas con las temperaturas del core, que subían hasta los 95 grados usando el disipador y la configuración originales. El cambio de pasta térmica tradicional funcionaba bien al principio, pero tras una o dos semanas de uso intenso, las temperaturas volvían a dispararse y tocaba desmontar todo de nuevo, algo que acaba cansando después de hacerlo cinco veces. Ya había pasado por varias marcas conocidas como Noctua con poco éxito, hasta que decidí probar el KryoSheet. Al principio dudaba si funcionaría bien, pero unos día con el y las temperaturas se mantienen estables como el primer día. Y eso que le meto mucha más caña de lo habitual, intentando forzarlo lo mas posible y durante mas tiempo del que realmente lo estoy usando, a base de pasarles tests de stress sin parar. Ahora mismo los cores de la CPU están entre 60 y 65 grados, y el package sobre 55 y con el sistema a plena carga. Un aviso importante, hay que tener cuidado al cortarlo si no tiene el tamaño exacto que necesitas. En una dirección se corta bien, pero en la otra tiende a deshilacharse en pequeñas fibras. Recomiendo usar tijeras muy afiladas o mejor comprar directamente el tamaño adecuado. No lo he reutilizado ni pienso hacerlo; prefiero poner uno nuevo cada vez. Es un gasto extra pero vale la pena por no tener que estar desmontando el sistema constantemente. El tema, es que es conductor de la electricidad y puede freírte la placa si hay un contacto donde no debe, así que cuidado. Otro punto a tener en cuenta es que funciona mejor con superficies planas ya que al ser tan fino no puede rellenar huecos grandes. En mi caso, con el MINISFORUM y su procesador de alto rendimiento, ha sido la solución perfecta a un problema que me traía de cabeza desde hace tiempo.
