Disable fan management on Dell Poweredge SC1425

Some rackmount HP machines that I've worked on in the past were known to run their fans at full tilt until a proprietary driver or software package is loaded in the OS. Then they would be relaxed down.

What OS are you using? Have you installed all of the recommended drivers/packages?

If you are concerned about the fan speed (and noise) consider this. On my Poweredge 2500, the only way I've found to control the fan speed is to adjust the temperature thresholds. If the maximum temperature is too close to the current reading, the fan spins faster trying to cool it off. When you raise the maximum temperature, the fan relaxes. So check to see if your thresholds are set too low.

Of course, if your thresholds aren't set too low, then you have a separate issue regarding cooling.
