I am trying to use GKrellM ( to monitor my system's fans/temperatures (I am trying to undervolt the fans a bit to make the systems quieter), but there don't seem to be any sensors available. I have lm_sensors installed.

Try executing the sudo sensors-detect command in console.

You'd have to use "fancontrol", not gkrellm. Gkrellm is a system monitor app. Fancontrol app comes with lm_sensors. AFAIK. Here ( is a manual. And you have to run "pwmconfig" with root to configure it up. The daemon will speed them down every time your PC boots up. Hope I was a bit of help..
