The second fan on my card (Sapphire Radeon RX570) is on full speed and extremly loud. It happens randomly when I start my pc or after some time running. Sometimes its fine for a few weeks and than the problem starts again.
I tried to control it with software (wattman, afterburner, speedfan) but they seem to just control the first fan.
Bios updates, driver updates... didn't solve the problem. Any ideas?
