Any way to adjust fan speed/noise on the Dell Optiplex 960?

My new Dell Optiplex 960 has a really loud fan. I hear that the 760 had some bad fans with the same problem. I've had no luck contacting dell via email or chat (I'll try calling them later this week).

Just wondering if anyone had any solutions other than those in the Question on the Optiplex 760

SpeedFan may be able to reduce fan noise:

SpeedFan is a program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips. SpeedFan can even access S.M.A.R.T. info and show hard disk temperatures. SpeedFan supports SCSI disks too. SpeedFan can even change the FSB on some hardware (but this should be considered a bonus feature). SpeedFan can access digital temperature sensors and can change fan speeds accordingly, thus reducing noise. SpeedFan can find almost any hardware monitor chip connected to the 2-wire SMBus (System Management Bus (trademark belonging to SMIF, Inc.), a subset of the I2C protocol) and works fine with Windows 9x, ME, NT, 2000, 2003, XP and Windows Vista. It works with Windows 64 bit too.

You can change to Dell part no : R434D (Thermal Sensor Cable)


you can change only the electronic transistor 2N3904 which is the sensor.
