I have a problem with the Radeon R9 390 graphics card. While I do not move my mouse after 5/6 minutes, the fans turn on the maximum speed and the temperature jumps to 80 C. After starting the mouse, the problem disappears. Anyone have any ideas what is causing and how to fix it?, I have a problem with the Radeon R9 390 graphics card.
