    My SMC Fan Control app seems to be corrupt. It seems to think the base speed for my 2012 2.6 mini is 2300rpm (which was a setting I used once) and does not give me options to move the slider or input a value below 2300 even thought the default speed is 1800.

    I simply want to remove it, but each time I delete the app and download a new one it keeps telling me the base speed is 2300.

    I have reset SMC (Sys Mgt Ctrl) and PRAM. After I reset the SMC the fan speed goes back to 1800 (using iStat Menus to check), but as soon as I start up SMC Fan Control it goes back to 2300.

    I believe there must be some hidden file some where I need to delete. Any suggestions?

    SMC Fan Control saves the min/max values of the fan to it's .plist file.

    The poster in this thread had the same problem as you with just different fan values and found that by editing the .plist file and manually changing the min value it went back to normal.

    Personally I'd try just deleting any associated .plist files first and see if that corrects the problem before going and manually editing them.

    Thanks Tag. Seems to have worked. I deleted the files and deleted the app then shutdown and restarted and then re-downloaded it. Fan speed is back to the normal 1800rpm now.

    I have an older (2010) iMac i3 and have iStat Pro installed and haven't had any fan-related problems but do you know where I can find the nominal fan values for this machine to see if I need/should get SMC Fan Control installed? Tnx.
