Review: Great Purchase - Great Product. I used Liquid Metal but needed a less risky but great option so i tried this. Works almost good as LM. No Throttling. Before using maybe put in fridge as it is easy handle when cool.
Review: Good thermal pad - Put this on my rtx 4080. Taking apart the GPU was pretty simple. I cut the pad down to fit the die and it worked perfect. Temps dropped around 10 degrees celsius.

## Features

- PTM7950 is a highly thermally conductive Phase Change Material (PCM) that lasts longer and is more effective than tradiational thermal paste.
- Size 31x50x0.25mm, Phase change at 45°C, Thermal Conductivity: 8.5 W/m.K, It is normal for it to melt at high temperatures.It achieves good heat dissipation performance through repeated melting and solidification. Note: it requires technical and operational skills, it is recommended to use under the guidance of professionals
- PTM7950 is a proprietary material that provides superior reliability (pass 150˚C baking 1000 hours, T/C-B 1000 cycles) and maintains low thermal impedance (<0.04˚Ccm2/W @ no shim), making the PTM7950 series desirable for high performance integrated circuit devices.
- PTM7950, based on a novel polymer PCM system, exhibits excellent interface wetability during typical operating temperature ranges, resulting in extremely low surface contact resistance.
- Package include: 1x PTM7950 Thermal Pad 31x50x0.25mm, 1x Screwdriver, 1x Cleaning Wipe, 1x Spatula, Finger gloves, 1x Cleaning Brush

### ⭐⭐⭐⭐⭐ You can stop searching now, this is the best thermal paste for your PC
*by M***P on March 31, 2025*

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.
