I guess your machine belongs to the category of mine, a plain old IBM970. No FX, right? You can check your /var/log/messages and see if there is an entry about 'smu'. If not, then you're lost at the moment. The fan management support for these machines is lacking atm. Only the newer machines (G5) which have an IBM970FX/MP have support for a simple fan management. I even guess your CPU clock is not running at its highest speed, right? Would be great if you could post your dmesg. Thanks, Andreas
