I recently bought a rx 470(Sapphire Nitro OC edition) for building a new PC. I am a complete noob to PC building and thought my GPU was pretty hot. so i checked the temperature using GPU-Z and saw that the temperature was 75 degree celsius. This is not the temperature recorded while gaming,it's just the temp while normal browsing. I havent played any games on it yet, so while gaming wold the GPU hit 90. I am quite worried and is this harming my system in any way. can i reduce the temperature?I havent overclocked it
