CPU, case fans on full speed, full time

[krrh]

New motherboard. Old case, CPU, heatsink/fan and case fan. Both fans worked correctly under the old motherboard -- usually totally silent. Along comes my new Biostar P4VMA-M and new power supply, and all the fans run full speed constantly.

The power supply fans aren't the noisemakers, and as far as I can tell, are running as they should. The CPU fan, however, stays around 5,000 RPM. The case fan stays around 2,000.

These fans continue running after I put the computer into standby.

I've tried to regulate them using Speedfan. The application has no effect.

The BIOS seems to have no mechanism for fan-speed control. It only shows me how fast they are running.

And, finally, my CPU temperature stays around 30C when idle and gets to about 38C under a heavy load. These seem far from hot to me. I'm running a Socket 478 Celeron D 325.

So, do any of you forum members have suggestions? I installed the motherboard myself -- a first -- and suspect I might have done something wrong. However, the rest of the system seems to be working fine.

Thanks in advance.

I've never used a Biostar MB, but you get what you pay for. It's very possible that it just runs the fans at full speed all the time.

I agree - the board probably does not support controlling fan speed based on temps. Speedfan needs cooperation from the hardware, so that's probably why it's not changing the fan speeds either.

No idea what this is supposed to mean.
But, you can always try updating theBios and chipset drivers.
