OK, I'm fairly certain now that some kind of sensor somewhere in the system which I can't measure is contributing to determining the CPU fan speed.

See, my system's actually fairly close to the heating vent for the room... there wasn't any way around that. When the heat comes on, if the system's idle, the CPU fan speed slowly rises by about 500 RPM, then when the heat goes off it slowly drops back down... yet the most the idle temps increase by is 2 c during this. 2 c normally only covers about 200 RPM, not 500 RPM.

Also, I was able to get the system up to about 95% CPU usage peak during rendering of my latest ADG episode last night. I know from past experience that running the CPU at full power typically brings it up to 62 c. However, the highest the CPU temp got this time around was 60 c, and it only peaked there as it mostly sat around 59 c. Granted, the CPU fan was going like a bat out of Hell, topping out at 5500 RPM and mostly sitting around 5300 RPM during the rendering.

So, even though the CPU fan is running faster due to the warmer environment in here and the proximity to the heat vent for the house, the CPU temp itself is ending up slightly cooler as a result of the generally higher fan speeds. *shrugs*

So you can't put it up on your desk, or place it on a shelf?

Nope. Way too big for that. Even if it wasn't, there's barely room as it is in this tiny little room for more than my desk, chair, computer and a single-sized bed. I'm having to keep the closet door open just to give me a little more space to work with. :P

I can report the same type of experience with my fx-8350. The cpu fan likes to randomly speed up for no real reason. The single cpu fan is louder than my quad 120mm case fans and tri gpu fans put together. Half the time room temp is like 50F. . .
