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.

Greatly improved the temps on my i5 13600K compared to a thermal paste I used before. Hovering arond 30 degrees C or less at idle and I have almost never seen it go above 90 degrees C during heavy and sustained workloads. Was a tiny bit finicky to install with shaky hands at first, and the tape was slightly difficult to remove, but I got there only after a couple of minutes of trying and the paste didn't tear. I'm sure this would have been a lot easier if I cooled the paste down even more before applying, so be sure to follow the leaflet inside the box. Obviously can't speak for the long-term usage performatnce, but from what I have heard, these things last a long time.

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.

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 .

Temperature wise it seems to be more effective than standard thermal paste by a few degrees. However you only get enough for one CPU application and it is difficult to apply so I doubt it will be reuseable. On balance is a good product but the cost/benefit ratio is not amazing.

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!

The actual performance of the pad is quite good, but the problems in my opinion outweigh the mild thermal benefits compared to thermal paste. the installation is actually harder that you'd expect, it adheres more to the plastic protector it comes with than your CPU. the first one of these I had tore while trying to remove that protective film. and as for durability, the idea that you could reuse this, thats mad. I only had it on for a few weeks before wanting to change my cooler and when taking out said cooler the CPU came out with it! almost glued on... I'm lucky it didn't damage my motherboard or CPU. All that said and done, maybe I'm not the best use case example. but then, who is this for? I'd be hard pressed to recommend it to a more novice pc owner, and someone who is more advance may well be using liquid metal or more advanced pastes. I think at the price its also hard to justify, when you could buy a tube of paste that lasts many reapplications. perhaps if they reduced the fancy packaging they could drop the price? do your research, watch some videos, and think about what exactly it is you want from your thermal compound, I think most people will be fine with just a standard thermal paste.

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.

Came in nice, neat packaging. Works very well.

I own a Lambda Tensorbook 2 (basically a Razer 15) for a few years now. Some days ago, I opened it up, and re applied thermal paste (MX-40) carefully on GPU and CPU. The improvement was significant, but it showed two hotter spots which were still causing some throttling. So I decided to try this product. I left it in the fridge about 10 minutes, cleaned the old paste, cut the sheet into two pieces for GPU and CPU, and applied the sheets over them. BOOM. 5 seconds. The peel is a bit hard to remove, technical tweezers helped. I cut it slightly bigger than the chips, and still got some left for a change in the future. TEMPS ARE INSANE! The PC sits now at 4300 MHz across all cores in PL2 (boost mode) with avg temp around 80 (more or less 20 seconds boost, 90 W), and at 3700 all cores in PL2 at about 60 degrees. ZERO THERMAL THROTTLING. The GPU couldn’t get hotter than 61 degrees in 5 minutes of test load. My fans are now basically never on. I am very happy with the purchase.

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.

Excellent cooling. CPU maintained at 38C at idle versus 46C with cryosheet which found has uneven clamping when replacing to phaseshift.

Suggerita dall AI e Utilizzata per cambiare la pasta termica della mia Xbox series X ormai secca e inutile dopo 5 anni e devo dire davvero efficiente ! Già dalla prima accensione tira fuori un calore che ricordavo solo a console nuova! Non è molto difficile da applicare, bisogna prendersi il giusto tempo e magari guardare un video su YouTube prima. La console è tornata silenziosissima ed in previsione dell estate e considerando le condizioni della pasta termica originale ormai asciutta è completamente fuoriuscita di sicuro ne salvaguarderà la durata e lo stato di salute a lungo. Consigliatissima! Raccomando di metterla in freezer 8/10 minuti come consigliato dal produttore per poterla tagliare con precisione e di fare qualche ciclo di mezz ora accesa/spento per portarla a regime .
