Mine normally (SMART) is above 49° (120 F), probably more on the 130-140° F range and the HD fan can be fairly loud when it gets to 140 and higher -- over 5200 RPM . >Things have tended to 'read' a little cooler resulting in less fan >activity since 10.3.8. My fans run differently now - less logically, maybe. Sometimes the HD fan races when below 140 (SMART). >Also running Processor Performance on 'Automatic' makes a substantial >difference in CPU temp and fan activity. Switched mine to Automatic several days ago, but haven't noticed temperature/fan change. >I leave mine on 'High' because the fans are so unobtrusive. > >Just out of curiosity, do you 'sleep' yours? Lately, I will occasionally sleep mine. It gives it a chance to cool down and makes me feel better. Tom Miller ..................................................
