Well updating the drivers and CCC is what got me here in the first place.
The previous version 9.xxx had the overdrive but when I updated to 10.xxx (after removing the previous drivers) the overdrive went away.
I updated due to the fact that the previous version was having some issues (VPU recovery) after playing some games for a while. The new version fixed that issue but now no overdrive.
As to the gpu fan there is no real way to tell what its doing thats actually the main reason I want the overdrive.
Oh and to Frau.... If it works dont fix it
