Hello, I have Sapphire R9 380 Nitro model. When I monitor the graphics card fan it doesn't work up to 50 degrees. When it reaches 52 degrees, it suddenly reaches 700 and sometimes 1000 rpm and then stops. This cycle continues constantly. There is no problem in games, but when it is idle and entering the bios, it constantly accelerates and slows down. I downloaded the Speed fan app last night and uninstalled it after a while. That's what happened after that. PSU is new, Corsair Rm750x. I reset the Bios, I updated the Bios, I formatted the computer, I reset the VBIOS but it didn't fix it.

Please help me..
