Review: Perfect Laptop Replacement - Asus laptop that shipped with liquid metal for the CPU and thermal paste on the GPU, I saw a recent LTT video about an asus failing because the liquid metal leaked due to not enough mounting pressure, and then the PS5 issues, and then other asus users saying to let the laptop cool down before putting it in a bag/vertically. The vidoe put me over the top because it turned out the PTM7950 performed better ANYWAY. So i just decided to do it, the hardest part was removing the liquid metal from the SoC... By far, that took forever and was tedious and time consuming. Putting this on, was extremely easy though. I cut a couple pieces to size for the GPU and CPU, and that was it. I did refrigerate it in advance and I also used some fine precision tweezers to remove the films. Very easy actually. And the temperature of my laptop IS lower than ever. consistent idled at ~32C, now it's down around ~27C - and under load its sustaining higher clock speeds. Totally worth it immediately, better performance and peace of mind. Probably not the genuine honeywell stuff, but it's good so I also don't care.
Review: The real deal - People keep spending a lot of money for branded PTM7950, but this is the real deal and for half the price. Temps dropped from 2 to 6 degrees C and they keep getting better as the pads accumulates heat cycles. The GPU was cool to begin with but still got better temps, and the CPU went from sustained 3.9ghz to 4.3Ghz, and with better temps at that. The thing with PTM7950 is that you need to cycle it to get better results: run a 30 min benchmark, use the PC normally, and turn it off when not using it at least for the first few days. After 3 or 4 days, the compound will get better it gets hot and cools down. Also, don't play in hard mode: use tweezers to remove the plastic layer, put the pad where it belongs, press against the die to make sure it's making contact with the whole surface, and once it sticks it's really simple to remove the top plastic part with the same tweezers. Easy.

### ⭐⭐⭐⭐⭐ Perfect Laptop Replacement
*by B***D on November 12, 2025*

Asus laptop that shipped with liquid metal for the CPU and thermal paste on the GPU, I saw a recent LTT video about an asus failing because the liquid metal leaked due to not enough mounting pressure, and then the PS5 issues, and then other asus users saying to let the laptop cool down before putting it in a bag/vertically.

### ⭐⭐⭐⭐⭐ The real deal
*by G***E on August 21, 2026*

People keep spending a lot of money for branded PTM7950, but this is the real deal and for half the price. Temps dropped from 2 to 6 degrees C and they keep getting better as the pads accumulates heat cycles. The GPU was cool to begin with but still got better temps, and the CPU went from sustained 3.9ghz to 4.3Ghz, and with better temps at that.

Easy.

### ⭐⭐⭐⭐⭐ Best Thermal Outcome
*by O***. on March 4, 2026*

PTM7950 is the best thermal outcome, but not as easy to install as paste. If your motherboard is out of the case its easer, but if you are like me and try to install on cpu in the case, it can be a challenge. It needs to be frozen in order to get the plastic protective film off of each side. Pad is very thin and flexable at room temp and sticks to plastic film. I suggest applying the pad near the freezer as you will need to freeze and refreeze several times to get the film separated from the pad. Use the stickers one on top and one on bottom to get the film to pull away from pad partially (1/2 away) on each side before you install. Refreeze, a few minutes, remove one side of film and loosely set on cpu pressing lightly on the side to the pad the film was not loosened and remove top film. Install heat sink, do not try to adjust or press down as the pad goes from frozen to room temp very quickly. Once installed there is a burn-in period you can use prime95 if you want to hasten the burn-in. I took off Arctic Silver and applied this pad and my temps went down 8 degrees and the AMD CPU now clocks 100hz higher under load. My AMD 9-5950x now idles at 42 degrees during normal use and 89 degrees maxed-out. Its work the effort.
