Well, mine makes a very slight hissing/whining noise when idle. Not audible unless the room is near silent, though I must admit.
It also produces the 'moo' sounds at idle, which are audible and very annoying. Particularly distracting in a quiet library.
In addition, anywhere near load, the fans rev up as if the thing is about to take off. Something as mundane as an video conferencing with iChat causes the fans to gradually rev up to full blast.
Far louder than my previous PowerBook G4 1.67GHz ever was at full load, or even my Dell D600. Yes, I realise with iChat the CPU is encoding video/audio in realtime, but this thing is loud.
It also trips into thermal panic and throttles when hitting full load. Even with the fans on full blast, it isn't enough to cool the thing down it seems.
Suffice to say, a replacement is already on its way.
Quoted my own post now that my new MacBook has arrived.
What a difference between the two. Side by side, they look identical but the new one does not moo at all.
In fact, whereas the fan
motor on the old one becomes very audible as it ramps up, with the new one you can barely hear it except for the sound of air gushing through.
The old one would make a sharp and constant tone of noise when the fan came on, which is why the moo was so annoying when it constantly came on/off, since the fan noise was very sharp and a bit like something grinding or buzzing.
The new one runs a few degrees cooler and the only audible noise when the fan comes on is the sound of air going through; no or very little motor noise.
Temperatures take longer to reach their maximum, although both top out at around 72-75 C. The old one is much noisier at this temperature though. The new one also cools down much faster.
Still a bit warm for my liking, but otherwise it's a huge improvement on the first unit.
