A program developer going by the name Noda (haven't heard of him before, but I sure have now!) has developed something akin to eeectl (for the eee) for the Aspire one. It controls the fan speed, cpu settings, screen resolution and other settings that you really want to tinker with.
The thing that makes me so happy about this is that instead of having to run 5+ apps to do all these, I have them all in one nice tight little package.
You can download the program here.
