Fan spinning to fast on MB ??

brasiliangringo · Nov 24, 2009, 08:40 AM

I have a unibody MB which seems to be spinning too fast - 5400rpm @ 67c??

I am only running Firefox and mail. Room temp is about 19c.

The issue is possibly as result of latest OSX update which is currently Mac OS X 10.5.8 (9L31a).

Thanks for any suggestions.

Are you on Youtube or Hulu?

No.

Are you on sites with lots of ads or any other type of Flash animation?

OP, have you checked the 'Activity Monitor' to see if any processes (e.g. Safari) are maxing out the CPU?

@miles01110 - no flash..

@gjw4u - Firefox 10% CPu. That's it.. nothing else quantifiable to mention.
