All right guys, come on let's talk about this. i just got my new Dua 867Mhz. Boot up in OSX, nicely. i'm a music producer so I don't have anything to do yet in X, so switch to OS9, and there it is. NOOOOOISY FAN, that doesn't stop. i went back to OS X, and fater boot up fan STOPS. Obviously called tech suppor in apple "care" and nobody knew anything ( not even that these new babies come with ata 100 and 66,??? what the f these people behind the phone??!!!!!) GUYS, PLEASE, TELL ME IT'S A GENEREAL ISSUE AND THAT ITS NOT HAPPENING ONLY TO ME!! Try boot up in both systems and see the noisy difference! THANX A LOT IN ADVANCE!!! Fernando.
