I have a new Optiplex 760 running Slackware v13 (x64). The power supply fan comes full on when I turn on the box and never slows down. I'm expect it to slow down after it senses the load/heat, but it never does.
This PC runs the latest Intel chipset (1Ch10).
I've loaded the kubuntu 9.04 live cd and had the same problem. Could there be a bad sensor some where or do I have a config problem.
