My first MacBook Pro had no noise problems whatsoever. So except for the constant kernel panics, it was great. My *new* MacBook Pro is perfect in every way except that it *does* have an incrediby annoying, very high-pitched CPU whine that gives me a headache. Daniel Jalkut has documented all of the various noise complaints exhibited by different MacBook Pro models and provided two potential solutions. The MagicNoiseKiller app solves the problem for me, which I think will give me back my sanity, at least as soon as the residual ringing in my ears goes away.
