I just downloaded AMD Overdrive today incase i want to overclock my AMD A10-6800k or even my new GTX 660 SC if possible, either of which not right now. Anyways, i also heard you can change your fans' speeds which i wanted to do right now. I open up Overdrive and go to the Fan Control section only to find everything is grayed out and i cant change anything. It shows i have 4 fans supposedly (FAN0, FAN1, FAN2, FAN3). I dont know if even that is right because i only have one stock case fan and the stock cpu fan(heatsink?), unless it also counts the fan built onto the gpu and the fan built into my Corsair CX430M psu? Anyways, how can i enable the fan control option? Any help here? Comment if you also have the same problem or how you fixed it. Thanks!
