Bought this R7 360 gigbyte version second hand from gumtree. The owner said it was barely used which i believed since it was very clean. I popped it in my system and overclocked the memory from 1500 to 2000 and clock from 1200 to 1250 but was surprised to see it idle at 47c and maxed at 85c playing fortnite or for honor. Are these temps normal? and can i lower the temps somehow by changing the stock thermal paste?
