I received a broken Radeon HD7870 from someone. Looked like it had overheated quite much, because the fan immediately went 100% when I put it in my pc. I took it apart, cleaned of the dried thermal paste, applied some new and the fan didn't do much then. But it still didn't work, my pc didn't boot. So I put the gpu in de oven, and it worked. Only problem is, it idles at 60C and when I play Just Cause 3 it gets 90 C and I've even had 98 C. The vram got 104 C. What do I do? These aren't normal temperatures.
Edit: I tried underclocking it but it doesn't help. it got 98 C so I Alt + F4'd out of it. Not the whole thing is broken, everything on my main monitor has lines over it.
