Hello there..

This morning suddenly I noticed something peculiar. I have this iStat Fan Sensor running in the menu bar and found out that the Left Fan spins at 236rpm and the Right Fan at 5996 - 6005rpms. Perhaps it used to be 2400 or 3000 rpms in avg. most of the time for both fans in an idle state.


I'm beginning to think something is wrong.


Is it normal or something really going wrong? I have my MBP 2010 15" model serviced back in 2011 and they changed my logic board. Never had any issue about this fan issue since then.


So any idea what is going on?

MacBook Pro, OS X Mountain Lion (10.8.2), MBP 17" Core i7 Processor (2.66MHz)
