I have tried lm_sensors with Suse 9.1, the current Mandrake, and the current Ubuntu. In the bios on my MSI K8T Master2 -FAR, I have the option to set a threshold for the CPU fans so that below a certain temperature they run quietly and not at the full 'sounds-like-a-jet-engine' speed. When I switch on they run full for a couple of minutes and then slow down to something like half speed. Under Suse 9.1 this all works fine, but if I use Ubuntu or Mandrake, enabling lm_sensors causes the CPU fans to run at full speed without ever going quiet. Why should this be so? Is Ubuntu lm_sensors doing something to overrride the bios setting? Otherwise, sensors appear to work fine. I'd appreciate any guidance you can offer. - Richard Kimber.
