They are spinning up under load (a little bit at least because the card is not getting hotter than 75°)
The problem is, they are not going *under* 1300 rpm - even on idle on windows desktop. This is bothering me right now, because the first weeks i couldn't hear them at all. (So in the beginning they were spinning down or even stopped completly)
Maximum in Wattman doesn't change anything:
Have you tried setting the fan speed to the lowest for min and max and see what happens?
You could also try an older driver if it worked previously.
No setting seems to change the fan's rpm.
I did a clean adrenalin uninstall and booted in safe mode with no adrenalin software installed and the fans were spinning loud. (Could not tell the rpm because no wattman was installed) A clean install of 18.1.1. afterwards did not change the high idle rpm.
Next i'm going to uninstall again and try an even older crimson driver.
