I have uninstalled SpeedSwitch already because I didn't like it

. Under AC the fan remains on but at a very low level. This is at everything set to maximum as well (GPU, CPU, screen). If you undervolt the CPU enough (1000Mhz?) I'm sure the fan will go off. On battery the temperature goes down to about 44 degrees with the CPU at 800Mhz, and the fan turns on again a little over 50 degrees.
