Anyone ever encounter something like this before?
I really hope it's a software issue tho I'd hate to have to RMA again.
I also have a Zotac Extreme and I've also observed some strange behaviour with its automatic fan control.
But I don't think it's hardware fault.
From what I have noticed, the fans start spinning at 50°c and are locked at 850rpm during 0% to 30%.
Thus preventing stop/start during low %.
Then they increase with the % (above 30%) as temperature rises as usual.
After the load, temp decreases and the fans stop at 40°c.
And you don't have control during idle, if try to set even 100%, the fans won't move.
But this is not the worse, because once I have noticed during benchmark when temperature was 75° that the fans rpm was at 0!
I checked and indeed they were stopped and forgot to start!
It can be really dangerous if you don't notice it!
I think Zotac has tried to do something smart to prevent start/stop behaviour during low load but has done something strange and buggy that I've never seen before...
