Hello, This past Monday I took delivery of a brand new 13" MacBook Pro. This is the first laptop I have owned and so far I am quite impressed by it. I am coming from a 24" iMac which ran like a dream. The MBP overall is very quiet but there is one thing that I am noticing with the fan on the right-hand side. It seems that for the most part it will run at a constant speed but every 10-15 seconds it makes a brief pulse or "whoosh" noise. This seems to be related to when the hard disk is being accessed as I can also hear the drive seeking. I have downloaded the iStat Pro widget and generally the fan is running anywhere from 1994-2001 RPM's which I believe to be normal. I have left the widget open for quite some time and when the "whooshing" or pulse noise occurs the RPM's don't seem to change. I just want to verify that this is normal and that this fan isn't going to crap out or become a pain in my side down the road. Thanks in advance!
