Hi guys i currently have a sapphire r9 380 nitro 4gb at idle its always in early 50c. When playing a game like a resident evil 2 remake its going to early 80c. Im sure this is to hot also its dual fan. When i check in global wattman its showing 423rpm fan speed when fan not moving at time then suddenly both fan start and stop this continusly happens then on global wattman even when fan hasnt spinned in 5mins it shows that fans are running at 437rpm and temprature is 51c im confused why its doing this also more confused why its idling at 50 reaching 80c when playing a game any suggestion or advise what this problem could be why its behaving like this?.
