I am having a problem, it was all working fine until I reinstalled the SMCFANCONTROL application because I thought there was a newer version. Now my lowest fan speed is about 4000rpm. It wont go down. What can I do? I already uninstaled and reinstalled using APPZAPPER, I shut down my mac, nothing worked, Im using a 2.2ghz mpb with 4gb ram.
