Lately my radeon 4350 has severely increased its temperature at seemingly random moments.

I could run a game for over 4 hours without the temperature exceeding 70 degrees on one day while the next day it would reach temperatures near 90 degrees merely to show my deskop screen.

It seems to decide if it will overheat or not when I boot up the pc

At first I thought it would be the fan but it seems to still be in proper working order so getting a new one seems rather pointless.

I hope someone would be able to give me some insight on what part of my pc causes the overheating so I can replace it.
