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!
