My GPU overheats, and then my whole screen and computer freezes.

I have an AMD Radeon 7900 Series (7970) GPU and i recently opened it up and took out all of the dust and put some new thermal compound and it takes longer to crash, but it still crashes really fast, even with the fan at 100%. I checked that the fans are working and they do. The GPU doesn't go over 80°C without just crashing. The game I play is Fortnite.
Pc Specs:
4.7GHz CPU: AMD FX 9590
3GB GPU: AMD Radeon 7970
8GB 1866MHz Corsair Vengeance RAM (4GBx2)

I personally don't think 80*C in games mean overheating. I've ran a 8800GT which used to go up to 95*C in games, and a Radeon HD 3870 which runs at 82*C. At 100*C+ I would consider overheating.

My bet is that this is a driver problem. Uninstall the driver and try other ones.
My second guess is that there is something wrong with the gpu when it uses the full frequencyes for a longer period of time. Try to downclock your GPU a little with MSI Afterburner. Like 200MHz lower for both core and memory and see the aftermath.
My third guess is that the gpu itself became faulty.
