So this is a little odd and i wasn't able to find anything on google, also the LTT forum and tomshardware werent able to help me, so now im posting here.
First, my System: ASUS Z170-PRO, ZOTAC GTX 980 AMP!, Intel Core i7-6700K with an almost fresh install of Windows 8.1
So it seems like my GPU is locked in its automatic fan control wich keeps it under 60°C at all times.
What i want to do is make the card run more quiet at the cost of running hotter (around 70°C). If i try to set the fan speed (either by applying a curve or setting it manually) it will comply at first, but then return to its automatic fan profile after 10 seconds (See screenshot).
I have tried GPU Tweak, Zotac Firestorm, and gave up at MSI Afterburner, all of them had roughly the same effect. i might mention that i had FurMark Running all the time while testing.
I might add, Speeding the fan up also has no effect
