[SOLVED] High gpu temps, but I do not know what's causing them...

So. I bought a used sapphire r9 280x dual x but with no fans or fan shroud, so I put 2 120mm fans on it,
I changed the thermal paste to thermal grizzly kryonaut and cleaned the gpu thoroughly. The temps are still reaching
close to 80C. But the one thing I did not change were thermal pads on the memory(there are no thermal pads on the VRMS), and
they were looking like they were in a pretty bad state.
Could this be causing my temperature readings to go really high? If not, what should I do?
 
And at least the r9 290s and 390s used to run hot. Just make sure to keep good airflow around the card also. Did you hook those fans to the motherboard? You might hook them up to ports on the board vs hooking them to the header on the card, then you can use the bios to adjust fan speed on them. Maybe set them to like 60% and see if temps go lower.

Those temps are fine on those cards. 280 and 290 series are as bad as vega64 ones, they're pretty much heaters. You could try to undervolt using the adrenalin software to shave off some degrees but im telling you, 80/82 degrees are completely fine on those cards.

I did hook up my fans to the 4 pin on the motherboard, and I set the fan speed to 100%, because I thought that 80c was too high.

Ok, thank you for the answer!
