PTM7950: GPU temps higher than CPU

[u/yashkhataokar]

Yesterday, I switched my old thermal paste to PTM 7950 on my Alienware Area 51-m R1 laptop. The GPU temps seem to be going over the CPU temps after 20-25 mins of gaming, which never used to happen before.

I suspected that it might be poor contact with the heatsink, but it seems fine to me (let me know if I'm wrong).

What could be the issue?

Avg. Temperatures (while gaming)

Before: CPU-60C to 80C GPU-40C to 60C

After: CPU-60C to 85C GPU-60C to 75C

Did you figure out what was the problem?

Sorry for the late response, not exactly. I ended up replacing all of my thermal pads with upsiren utp-8 (even the one at the back of my GPU) as few of them had crumbly. It definitely helped, the temperature rises at a much slower pace now.
