[QUOTE="chscag, post: 1153176, member: 46727"] Welcome to the Mac Forums. Fans should be running as long as the machine is powered up. Normal Fan speed at idle varies with the model of Mac you have but generally it should be in the neighborhood of 1800 to 2000 RPM @ 47 to 55 degrees C. You can check all those readings by installing the free [URL="http://www.macupdate.com/app/mac/23049/smcfancontrol"]SMCFanControl[/URL] application. Just use SMC to monitor the settings, not to change them. A better application for checking on all your computer's vitals is [URL="http://bjango.com/mac/istatmenus/"]iStat Menus[/URL] but it's not free. It's what I use and well worth the $16 registration license. [/QUOTE]
