Like the title says i have issues with the fan in 7770. When the computer start it jerks a little maybe 2 circles and then it stops. I tried some very demanding games and the GPU is at 75 celsius and the fan still wont start. I tried usingMSI Afterburner and the fan only start spining from 75-100 which is very loud. If i try anything below 75 it wont even start, BUT if i first put it on 75 i can gradually go down to 60 but the spinning is inconsistent and it stops after 5 seconds. Can anybody tell me if my GPU is broken or is it just some feature ( i dont think that 75 celsius is normal tbh) thanks for the answers.
