I have a Compaq Presario R4000 running Ubuntu Linux 9.10 karmic. The system runs very hot and one of the fans is wither never running or always running at the slowest speed. For a while I thought the fan was dead but I just updated the BIOS (Phoenix BIOS) and during the update, that fan suddenly kicked in at full speed!
How can I get that fan to spin up during normal usage? I have tried
sensors-detect but all it found was
k8temp, no fans...
(SpeedFan under windows found no fans either)
