Although the problem appears to be rare, some users are reporting an inability to return fan speeds to their default settings after modifying them with the tool smcFanControl, which is intended to keep portable Macs cooler by changing the level of fan activity which is dictated by settings in the SMC (system management controller).

One reader writes:

"Hello, I was wondering if you could help me with a big problem I've been having. I tried smcFanControl and it worked great. Then, I tried Fan Control and I didn't like it so I deleted it. Now my fans won't go below 2000 rpm and I'm only running one program. I've tried using smcFanControl to bring it down but it will go down to 1600 and then it goes right back up. Please help me revert my fans to the defaults."

If you are experiencing a similar issue, please let us know.

    you must uninstall Fan Control completely... go to http://www.lobotomo.com/products/FanControl and follow the directions at the bottom...most importantly resetting the smc of your mac... also, if you wanted just stop fan control once per start-up you can go to activity monitor and find fan control daemon, press quit and type your password...then start smcfancontrol and it will now be in control...but only until you restart the computer, so you may want to do a full uninstall of fan control to avoid this
