[Honeywell PTM7950 Phase Change Thermal Pads/Sheets] Application, Tips, and Results

I decided to try this stuff out on my AMD Framework 13…

It seems to me that it’s working so well that the fan curve is now way off.

It takes longer before the fan ramps up than it did previously. Which means that the aluminum casing is (subjectively) warmer than it was previously… and that when I run something like Cinebench, it’s actually spiking up to like 95C before the fan kicks into a higher speed and eventually brings it down to 79C. (Screenshot below is from an earlier run).

I’ll probably pull off the heatsink and try again in a few days with a new piece to be sure I didn’t screw up the install, but it really feels like the fan is just confused by the low temperatures on the other sensors since it stays absolutely silent for so long after the initial load starts. (Not sure what that misread package temperature minimum of 5C is about either).
