[QUOTE="chscag, post: 1394761, member: 46727"] I use iStat Menus 3 (licensed, not freeware) so my temperatures are measured a bit differently than yours. However, for my iMac 2011 21.5" machine the fan speeds are as follows: CPU = 1200 rpm HD = 1098 rpm OPT = 998 rpm They pretty much stay that way from day to day. I don't leave my machine on all the time because of the severe weather we get here in Texas but after an 8 hour run the speeds are what I reported above. Just make sure that the intake vents at the bottom of your display housing are free and clear. The same goes for the exhaust vent at the top of the display. [/QUOTE]
