No Fan Control

I have a Gateway DX100S computer with an Intel (South Lake 3 G5) 915GV motherboard. The motherboard part number is WMEOEM915GVSEG5. My problem is that the fans seem to not be controlled or altered by CPU temps. My Celeron D 2.88 MHz, which I know does run a little hot, is running around 45 deg. C at idle..with the side panel off... in my unheated basement! The CPU fan, which blows across the heatsink, is not mounted directly on the heatsink.
I removed the heatsink and scraped off the overly applied heatsink compound, and re-applied a thin layer, but the results were the same. In the BIOS, there is a setting to enable or disable the auto fan control and when I disable, the fans run at full speed, dropping the CPU temp but raising the fan noise, and when it is enabled, the fan speed runs between 500 and 650 RPM. I looked for a BIOS update, but the current version is the newest.
Any thoughts other than an outside fan controller or possibly a heat sink mounted fan (even then if there is a problem with the motherboard's fan controller would it really help)?
Thanks!

BTW...here are the specs of the fan controlling system on the MB as per the Gateway website!

I don't believe it has anything to do with offending anyone it's just that sometimes a hardware specific problem may not have been encountered by many others.

Sometimes the ones that may be able to help simply haven't had the time to post a response yet.

Sometimes we just don't know the answer.

I read your post quite some time back but didn't have a solution other than to suggest that maybe your board was faulty.

I was just trying to find humor in the fact that no one was posting. I realize this is very specific problem and that the likelihood of someone else having the exact same problem was slim, but I figured I'd try. I hope I didn't sound like a whining child waiting for supper, I just thought I'd fill the space with a little humor.
I noticed that the thread was read a lot and I thank you all for doing so. If you don't have an answer, thats OK, I appreciate you reading!
