New at mining and I recently bought another cheap computer to mine on the side because I didn't want to reformat my windows 10 for nvidia mining with the GTX 970, bought a used ASUS R9 290 and was getting hash rates of 17 Mh/s on Claymore.
The temps were at 95C and that seemed to be normal for the AMD card. Regardless I took apart the cooler and applied some noctua thermal paste. Now I'm running without loud fan noise at a solid 65 to 75 C (if I keep my fan under 50% it goes to 75).
Getting 31.5 Mh/s after OC (34 reported on pools) I'm quite happy so if anyone have any problems you could try this if you tried all software solutions.
