Can you guys and gals with new macbooks and macbook pros install the istat pro widget and tell us what your fan speeds and temps are at idle and full load please? get istat pro here: http://www.islayer.com/index.php?op=item&id=7 For idle specs just let it sit there. For full load try downloading a 1080 HD trailer and let it play on loop for a few minutes. That will give a good reading. Let us know. Thanks.
