PTM7950 31x50x0.25mm Phase Change Thermal Pad, JOYJOM High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck ROG Ally CPU GPU SSD M.2 Laptop

I was very skeptical at first of this new "PTM" stuff I kept hearing about, so I decided to pick this up to try it with my new PC that's having thermal issues (it's my first Mini ITX build). I removed all the paste from my CPU and placed the PTM on it, remembering to remove the film from both sides, and tightened the cooler down on it. I could tell the difference IMMEDIATELY. My computer booted and dropped me to my desktop without me even realizing it because the fans never kicked up like they nomrally do. I ran a CPU stress test on my Ryzen 9 7940HX and where I was normally bouncing off my processor's TjMax within 5 minutes, I was now about 10 degrees (centigrade) below it after 20 minutes!Amazed at the improvement, I removed my GPU and swapped the paste for the remainder of the PTM - Another brilliant decision, because now my GPU won't even cross the 70 degrees centigrade mark even under full load! In an ITX build!I'd give this 10 stars if I could. It doesn't make a mess, there's no need to spread it around, it performs on-par or better than liquid metal, and your thermals will actually IMPROVE over time. I see absolutely no reason this shouldn't be used in any device you can repaste. In fact, I actually bought more and now all of my computers run this. If you're struggling to decide what paste to get, you can stop now and purchase this knowing it's exactly what you're looking for.

I used this with my 9800x3d and Noctua Nh-d15 G2 and the temps are good. It was easy to apply.

Highly recommended, significant improvement in every possible way and not difficult to apply whatsoever.

Great cooling and a mostly hassle free application with the exception of the film on both sides being a little tedious to get off well. After a bit of testing it's the only thing to reliably bring my GPU hotspot back to a normal range of 10-15C above the average that I've been able to find so far. One tip I did find that's worth mentioning is to run something demanding and do a quick shutdown after it gets heated up and loosen and re-tighten the main mounting screws which seems to improve the contact and improve the temps even further.

Works like normal thermal paste, nothing special.

Don’t do what I did the first time by leaving the plastic sheet on during installation. Otherwise, there is NO thermal alternative I’d recommend more.My workstation laptop’s CPU and GPU were running incredibly hot with the stock paste after a few years (around 98C for both) before I found out about these thermal pads and installed them. Now, my CPU doesn’t really get hotter than 85C and my GPU hovers around 80C when both are running at near maximum load.I do a lot of work with AI and these are amazing for the longevity of your processors, and the longevity of the pads themselves exceed that of regular thermal paste as well.

My RX 6750 XT had major problems with junction temps routinely hitting >105°C and the delta was 40+, even after re-pasting with Arctic MX-5 multiple times. This worked like a charm, my delta is now under 20 and the junction temps never exceed 80°C even after a prolonged FurMark run. It's a bit fiddly to install (the plastic sheets are hard to remove, much patience is required) but the results speak for themselves.

This is the real stuff, dropped my main gpu temps 10degrees Celsius+ and my hot spot way down. Pretty sure this is legit ptm7950. The smaller one for $9 was enough to do 2 gpu's. Put it in the freezer and cut it with a scissor and then put it in the freezer again to make it easier to pell the plastic off the ptm7950. I also did my vram with thermal putty at the same time. The upsiren thermal putty here on Amazon is the real stuff to get, don't get the knockoff stuff. Pictures are before and after. Also adjusted my fan a little for the second picture but I definitely took my temps down 10c+
