Same Issue
you need to remove fan control by deleting it from the startup menu in the library folder, then removing it from the preference panes also found in the library folder. Restart your computer, then run the app smc fan control to put everything back to normal......
To be safe.....reset you computers SMC by unplugging the ac cord, remove the battery and hold down the power button for 10 seconds......
Hey jugdish69. I'm having exactly the same problem. I originally had smcfancontrol before on my 2010 MBP and liked it, this was before my hard drive died of its own accord and I got a new one installed by apple and had to reistall everthing.
Anyway I just went to get a fan control app again and forgot the name of it, downloaded and installed fan control 1.2 which I then noticed was different and didnt like it. I decided to try and find what I now know is smcfancontrol.
I simply right clicked on the fan control 1.2 icon in the OSX Prefferences menu and clicked 'Delete fan control 1.2' and restarted.
Iv now installed smcfancontrol 2.2.2 and when I change the fan speed they change for around 4 seconds before going back to default.
I noted your suggestions however i do not seem to have a 'Startup' menu/folder or 'Login Items' as I read somewhere else, and my 'Preference Panes' folder is empty. Maybe suggesting fan control 1.2 was removed but somehow altered the fan settings? :/
Is there any other way to rectify this problem without the hard reset you suggested to save me having to reistall everything once more for what seems such a small app choice mistake? And do you think this would even fix the issue?
Thanks in advance for any help
