GPU temperature monitoring software

Physical. Some n00b tech guy thought it was dirt and scrubbed it off and he also damaged the fan fastening too, so only 3 pins hold it in place opposed to 4. Could also explain the temperature.

Lesson learned: do not ever take your PC to repair if you are capable of doing it yourself. For crying out loud, the “tech” guy thought the thermal paste was dirt? I mean, what was his previous line of work? Receptionist at the foyer of the local town hall?

Anyway, if I understand you correctly you've got one loose corner of your heatsink/fan which isn't pressed to the CPU properly. So if the fan speeds up and a lot of airflow pushes away from the CPU on the fans, then I guess that corner may be lifted a little bit so there's less direct physical contact on that part of the CPU.
