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

So it turns out that the 0.25mm material is performing very, very similarly. Makes sense I guess provided it’s the same material with only 0.05mm difference. Here are some numbers:

Can boost up to 60W

Cinebench R23

  • Single-core: ~1,528
  • Multi-core: ~5,562, got a max of 5,624. Can probably get ~5,700 like the 0.2mm material on a good run.

3DMark Time Spy Demo:

  • Overall: 1,679
  • Graphics score: 1,506
  • CPU score: 4,825

Idle temps: pretty much the same at around 39-41C in ambient temp/AC set to 72F.

AIDA64 CPU stress 10 minutes: leveled out at ~72C
AIDA64 CPU+FPU stress 10 minutes: leveled out at ~80C

stress-ng 2 minutes: ~77C

Geekbench:

  • Single-core: 1,678
  • Multi-core: 5,422

So yeah, from the numbers, I don’t think it matters much between the 0.2mm and 0.25mm. I’m personally going to just keep the 0.25mm in my system since that was my last application.

I think some extra takeaways from all this are:

  • The results have been very consistent across applications
  • Thermal performance is excellent (anecdotally)
