So long story short, computer has been turned off for a week following a power outage (I shut it down prior to losing power).

Upon re-boot, I got a CPU FAN ERROR - PRESS F1 TO RESUME message, and upon pressing F1, Windows started fine.

CPUID identified my core temps as ranging from 67-70. (quad core i7) Eventually, after an hour or so the temps all started to go back down to the high 40s-low 50s range. I normally see temps in the mid 40s.

It also IDs my CPU fan as having a max RPM of 245 when its normal range is 800-2800.

Could this be as simple as unplugging then re-plugging my CPU heatsink/fan back into the CPU header, or should I just get a whole new heatsink/fan?

So I moved the CPU fan to be plugged into my cha1 header (where my side case fan was) and moved my side case fan to be the CPU fan - that case fan had an adapter to allow it to plug into the CPU header and/or a 4 pin molex. I figured the CPU header could be dead. I guess I should have only plugged that fan into that before buttoning the case back up.

I no longer get the error, and temps SEEM to be back to the mid 40s. If I have that case fan plugged into both spots, am I going to cause anything stupid to happen?
