Improving thermals / lowering noise is always a challenge for us SFF enthusiasts and using a good TIM on our CPU- and GPU- coolers is almost crucial to get the best out of our small rigs...
I heard a lot of good things about Honeywell PTM 7950 Phase Change Pads and LTT said in one of his videos, it would perform almost as good as liquid metal... well, I wanted to see myself and did a few tests against my favorite thermal paste, the TFX from Thermalright
Test setup: Laptop PC, direct die application on I5-12450H and RTX 4060, fans set to MAX, 18C ambient
Test Results:
Honeywell PTM 7950, CPU thermals, 30 min. Cinebench
Honeywell PTM 7950, GPU thermals, 30 min. Timespy
Thermalright TFX, CPU thermals, 30 min. Cinebench
Thermalright TFX, GPU thermals, 30 min.Timespy
Things to consider:

Things to consider:
- PTM 7950 costs about EUR 15 ~ 20 for one application, a good paste costs EUR 10 ~ 15 for several applications
- PTM 7950 pads are very fragile and you need to be very careful during application, paste is easier to apply as it is more forgiving
- PTM 7950 is supposed to have better long term performance (I haven't tested), paste should be replaced after some time
- PTM 7950 performs not any better than a good paste like Thermalright TFX, at least according to my own tests
