1.First install the original version Fan Control. click "Fan Control 1.2.dmg" in the attached zip file. It may need restart after installation, if it's needed, just restart, no harm.

2.Copy the file in zip name is "FanControlDaemon" to /Library/StartupItems/FanControlDaemon （there is already a file exist with same name, just replace it, may need input root password）

3.Then copy "Fan Control.prefPane" in zip file to /Library/PreferencePanes just replace the existing.

4.Open terminal, run following command one by one：（If don't modify owner and group, mac will forbid it to be started up when computer booting）
4.1 cd /Library/StartupItems/FanControlDaemon
4.2 sudo chown root FanControlDaemon
4.3 sudo chgrp wheel FanControlDaemon

5.Restart Mac, then you can find fan control in "control panel" and start using it. 

6.enjoy it
