hi i've been trying both smcFanControl and Fancontrol I realy don't understand FanControl and when i am starting smcFanControl it work in a sec and then it gets back to normal.
What Mac are you using precisely, as currently all Macs have a fan(s) and even previous models (iBook, PowerBook and some PowerMacs) had one or more? And have you tried an SMC Reset yet? And before you ask how to do that: http://support.apple.com/kb/ht3964
