Sometimes the health monitor chip can control fans, and may control them in a variety of ways which lm_sensors may or may not effect. Why not try disabling lm_sensors and then do a full power reboot (shutdown, power down, power up) to see if lm-sensors is really making a difference? BTW- 2.5.5 is a little old in case you want to try upgrading (see our site: http://www.lm-sensors.nu ) Check for loose connections on the fans, or try letting the computer sit in the Bios screens for a while to see if the fan activity is different. (Beware: Bios's are often busy-wait and can make your CPU hot quickly if you fans aren't working right.) Also be sure you are using the correct chip driver and with the appropriate settings. Good luck!
