Thermal Grizzly - PhaseSheet PTM (50 x 40mm) - High Performance Thermal Pad with Phase Change Material | Durable, Non-Conductive Electrical | For CPU, GPU and Electronic Cooling

I delidded my i7 7800X, and put this staff between the core and the lid, as the paste applied by Intel was really bad quality. Custom watercooling loop with 1080Ti GPU. The loop is fine, as the GPU max was 40C. Before the job, the CPU went on 60-70C in idle, and peaks were well over 90C. Now idle 35C, in load 60-66, and no peaks at all. Easy to cut and apply on, it's just as sticky, as it needs to be. End one sheet could be enough for a CPU core (under the lid), and for a GPU. It lasts longer than paste, and it's not electrical conductor, but brings the same effectivity as the liquid metals. Price... it's not worse then other highend compounds.

Very happy with the product . Decreased my 7900XTX GPU hotspot temps by 20* . Highly recommend it to anyone who has problems with overheating or high GPU hotspots . Is not very expensive but not cheap either . Good quality . Remember to chill it before use , I kept it in fridge for 10-15 minutes before applying it for easy handling and fitting . Is a bit fiddly to work with but take your time and you won’t regret after .

First time using a thermal pad and it worked great. Really easy to apply and honestly much less hassle than paste. It was slightly wider than the CPU so I trimmed it a bit, not sure if that’s the correct approach, but it ended up fitting perfectly. After assembling the PC I ran a few benchmarks and everything looked good, with the heat transferring cleanly to the radiator. The price felt reasonable to me too, especially considering how well it performed.

It's been around 3 weeks now and I am really happy with my laptop temperatures after using PTM! For context, I have an Asus Rog Stryx laptop which uses liquid metal on the GPU and CPU. When I first bought it I didn't know much about liquid metal but thought it sounded interesting and was even quite excited to have a laptop with it. Boy was I wrong... After about 2 years of using my laptop and not having any issues, the laptop started shutting off while playing certain games. I tried seeing if I can sort the issue out through software changes but soon realized the issue ran deeper than that. It was clearly overheating and shutting down to save itself. I then opened the bugger and as you can see from the second photo, the liquid metal was anywhere but on the bloody GPU or CPU, hence crispy black spots in the middle. I did a lot of reading and decided to not use my familiar thermal paste but instead go for PTM and I'm glad I did. I won't lie to you putting it on is tricky. I bought 2 sheets for my GPU and CPU as it was my first time using it and I knew I needed to have space for error which I had. I recommend putting it in the fridge before using as it tends to soften up in your hands. Plenty of YouTube tutorials out there on this. Finally got it on as you can see on the first photo and put some thermal sheets on my VRAM and VRMs before closing it off. Temperature-wise, don't expect a huge drop, especially on your laptop as gaming laptops tend to have high temps. What was important for me is that the PTM keeps temps in the safe boundaries and saves my CPU and GPU and that it does. Overall, the quality of the PTM and packaging was really good and since I was able to do this myself rather than sending to a repair shop I got more than my money's worth. Would highly recommend!

I applied PTM to both the graphics card and the CPU. I'm not sure what the CPU temperatures were before, but on the GPU, the temperature in FurMark dropped by 20°C. Installing PTM is a bit tricky — it can be easily damaged. Initially, one side tends to stick firmly to the red strip it touches (the manufacturer should really improve this).

Listen, this stuff is great and easy to install (put it in the fridge for 2 hours, cut to size, peel off the film with tweezers and slap it down). The thermal performance was slightly better than Arctic MX-4 as I'm not using direct-to-die cooling, but I mainly bought this for the longevity. I must warn you, however, that if you do decide to replace your CPU cooler at some point like me, this stuff is not the soft flexible material that that it is pre-application. Once it's gone through some heat cycles it turns into CEMENT. Yanked my AM4 CPU right out of the socket even after running Prime95 for 30 mins prior to removal. I had to use a heat gun directly on the heatsink just to get the PhaseSheet soft enough to pry the CPU off. Thankfully no damage to the pins, but it's something to bare in mind. If you plan on keeping your CPU cooler for 5+ years, and want a very effective thermal solution where you never need to repaste, BUY THIS, IT'S GREAT. If you foresee yourself changing your CPU or CPU cooler anytime soon, STEER CLEAR.

If you have a overclocked CPU don't get it my temps were higher than before and yeah I did over 10 heat cycles and I even had full coverage on the CPU I went with Duronaut and dropped 10c watching YouTube and gaming things like at so basically I just wasted £13 on the phase sheet because of all the hype and I'm running a watercooled system with 480 an 420 and 360 rads so I should have low temps but didn't with the ptm paste for the win on this one

Tested on a 9800x3d at stock everything apart a - 25 CO. Thermally, not a meaningful improvement over thermal paste (at least when using an aio water cooler, maybe it fares better with air coolers). Fiddly application, you do need to follow instructions to the letter, otherwise you'll irreversibly ruin it. Also not exactly reusable and quite expensive. It's a no from me. And yes, this review comes after few weeks of use, so not exactly a curing issue. The only potential upside is it may (or may not) last longer than thermal paste. However, thicker pastes like mx-6 probably last just as long.

BD790iX3Dの冷却性能をどうにかしたいと思い購入。 高負荷時84℃〜86℃のところ、このシートに変更+ファン設定を見直して何度か高負荷、アイドル時を繰り返し馴染ませたると、だいたい76℃くらいになりました。 貼り付け前に冷蔵庫で冷やすと扱いやすくなり、綺麗に仕上がりました。 満足です。

Absolutely worth every cent. This stuff is amazing. My RTX 4090 after about a year stated to creep up to the high side of with the "Hot Spot" temperatures. Gaming the Core was in the 60c range and the Hotspot was in the 95-99c range. Pretty hot. So I bought this and applied it...EASY to apply by the way. very simple and stays in place easily. just to it in a cool area. Hotspot temp went down by 25c. at 62c on furmark my hotspot was 73c. so much difference. Amazing product. and it will ONLY GET BETTER over time and never needs replacing

Lo instalé en mi Asus TUF F15 Core i5-12500 H, estaba alcanzando temperaturas de 90 grados mientras jugaba . Hice limpieza de los ventiladores y cambié la pasta térmica que traía de fábrica por este producto y fue una maravilla. Logré bajar hasta 15 grados. Aunque es un poco caro, vale totalmente la pena.

Decided to try this instead of Honeywell one because that one is difficult to find. In terms of application and ease of use it's pretty much the same as Honeywell. And I suppose performance wise as well because it's been quite some time since I applied it and my gaming laptop has not thermal throttled or even needed to ramp up fans a lot. Overall it's quieter, colder and stutter free. I highly recommend to ditch normal compounds and get this instead. Follow instructions carefully and remember to clean every part of your heatsink and cooling system properly because using this.

Excellent getting 30c to 70c on hotspot watting for inbeding on a rx9060tx gpu 30c to 45c have got a few heat sinks an the back plate thou.
