Had to choose between thermal paste and a thermal pad on a laptop CPU today
I was replacing the cooling system on a Dell Precision 7730 that was hitting 98C under load. The original had a thermal pad on the VRAM but paste on the CPU. I went back and forth on it for about 20 minutes. Ended up going with a Honeywell PTM7950 pad for the CPU too since I read it handles pump-out better than paste in laptops. It dropped temps to 82C under full load after a 3 hour stress test. The only downside was cutting the pad to exactly the right size. Has anyone else switched to these phase change pads and noticed better long term results?

That PTM7950 is just overpriced hype. I've been using Arctic MX-4 paste on the same laptop model for two years now and it's still sitting at 80C under load, so I don't see the point in overcomplicating it.
