Ok I have done some testing and When I stress my GPU it speeds up my CPU HSF as well (by more then 50% or max speed.) What is going on here? CPU temps are close to idle +5c or so. the increase in RPM of my CPU HSF seems directly related to the heat of my GPU. I tested to make sure the reading was for my CPU by changing the speed in bios, and it changes for me. Anyone have any ideas what is going on? I do not think it is hurting anything but I am always curious.
