Thermal Grizzly PhaseSheet PTM 50x40 mm Phase-Change Thermal Pad CPU GPU

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!

Easy application, no mess - low temps - recommended. Fitted to a 5800x3d with a Peerless Assassin SE 120 - took about 3 mins to replace old paste. Handling easy ( both sides have a clear plastic lining ) - snipped a bit off to match the AM4 profile then pushed onto now clean CPU. About 3 mins later peeled the other side of plastic off then screwed the heatsink down. Temps from get-go 40C idle, 75C under load ( which is very good in comparison the the cryonaut it replaced )

There are 49 screws between me and my laptop's CPU. And every few weeks my Arctic MX-7 makes me wish I'd stuck with the stock 8 year-old thermal paste instead because the pump-out effect on this stuff is unreal. So I replace it, thinking this time my thermal paste applying technique will be better, but alas, the moment it's heated up it vanishes from under the CPU die. This PTM stuff is amazing. It outperforms freshly applied Arctic MX-7 and the more you put it through heat cycles the better it performs. I've gone from temperatures of 50°C trying to open Firefox to 36°C. If you buy this stuff instead of a thermal paste tube, even though you can only apply it once you're still getting better value for money (unless you build many PCs obviously). It is obviously a pain to apply. For laptops, I personally recommend cutting out slightly more than you need and then using a blade to cut it to shape after you've applied it because there is no way a human is getting that perfectly aligned - and if you don't on the first try, you have no choice but to scrape it off and try with a new piece.

My RTX 3090 had been randomly ramping its fans to maximum, and it turned out the original thermal paste on the die had succumbed to severe thermal shift over time, leaving it barely covering the surface at all. I decided to give TG PhaseSheet a go both due to the performance claims and because it should be more resistant to thermal shift. At the same time as applying this, I also replaced the baked thermal pads with TG Putty. The phase change material is straightforward to work with - you lay it on, and it does its job as the card heats up and the material transitions properly onto the die. No more guessing how much thermal paste is enough. It's recommended to chill the sheet for a little before applying (I put it in the freezer for 10 or so mins). I will say though, getting the plastic cover sheet off the PhaseSheet was a bit fiddly even with tweezers, as it almost didn't want to detach. The results speak for themselves. This, combined with the putty replacement solved the overheating issues I was having. Hotspot temperatures dropped significantly and the constant fan spiking is gone entirely - the card now runs quiet and stable rather than lurching to full speed every few minutes. I had more than enough left over after the 3090 to also cover the APU on my Steam Deck, which saw a nice temperature reduction as well. For anyone dealing with an older card where the factory paste has degraded, this is a great fix. Well worth it for the difference it made.

it applied fine with the cello-tape method, twice, but both times on my acer predator PH16-72 on the cpu that once had liquid metal gave me terrible temps, under no load hitting 100 degrees for a long time for no reason. applied again and same issue, another person 2 days ago on reddit used the same stuff as this, as me, and their temps were terrible too, and they did it twice aswell. something is very wrong with this ptm or its not compatible with acer predator helios laptop cpus that once had liquid metal

The results completely exceeded my expectations—the CPU and GPU temperatures dropped by 10–15 degrees! What's more, the temps are now even lower than they were "out of the box" when I first bought the laptop.

As the title says, this is a much better thermal material for on die cooling such as GPUs and consoles. It may be 2 or 3c hotter but this will NOT push out like thermal paste lasting forever. Using this on my GTX 1080 improved thermals by like 20c, did the same on a 4080 super temps were 1 or 2c worse but kinda expected. When applying it's a pain in the arse even with putting it in the fridge and trying to stick it down but you eventually get it.

Used this to repaste my old Razer blade 1070 (2018) That bad boy had some dried up paste and pads . This was a pretty simple swap - but I cant lie peeling this off the dies was a nightmare without it tearing. Its definitely good to work fast and while its cold - I made the "mistake" of heating up the PTM with a hair dryer to increase adherence to the CPU/GPU but i think it made it equally as hard to remove the final film layer - so I recommend reading the instructions (Cool it in the fridge) and watching some videos before hand and be PREPARED for the final refit before you take the plastic off - Great value for money and solid performance

War sehr easy aufzutragen und hat bei meiner 9070xt die Hotspot Temperatur von 89 Grad auf etwas 76 Grad gesenkt. Konnte das Pad einfach auf meine GPU aufdrücken und dann das obere Plastik abziehen, also auch da null Problem. Hat auch keinen Burn-in oder ähnliches gebraucht, hat direkt beim ersten Test funktioniert und gute Temperaturen geliefert.

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.

Hp omen 16: I dropped from 98c cpu to 83 in stress test And in gaming from 94c to high 70s

Another amazing Thermal Grizzly product. Easy to use, much easier and simpler than Thermal paste. Used it on my RTX3090 massive improvement of thermals. I highly recommend this product
