For some reason when i started a stress test the speed of the fan increases it says(I use AMD after burner) but the techo meter stays arond 3400-3450 RPM even if the fan speed increases frm 40% to 100% even from auto fan mode..so i tried manually setting to 100%..same result..it doesnt increase..also i even opened the case and checked frm 40% to 100%..the sound doesnt increase at all

Anyone has an idea why??And how to fix it?? And also can anyone tell me whts the max speed for their fan on their card at 100%??
