I just got done restoring my Macbook Pro. I freaked out when I could not uninstall Fan Control 1.1 and get it off my system. I also read a comment on how it (speculative of course) overwrote the firmware controls for the fan. Is this a harmful program? Does it screw up the fan controls? Am I alright now that I wiped everything from scratch? Did I embark on a bit of overkill?

The fan is controlled by the firmware, rather than the OS kernel. smcFanControl doesn't install or overwrite anything; you may be getting confused with CoreDuoTemp, which installs the 'speedit' extension. All you need to do to uninstall smcFanControl is drag it to the trash.

Also, with smcFanControl, it won't allow you to set a fan speed that is lower than the default.

Since you have it loaded, there isn't any harm is raising the fan rpms.
