    just got my new macbook and found out that whenever it reaches 65 degrees, it moo's. Do most macbook's do this and if I take this macbook to the store, will they replace it?

    Mine moos as well under the same situations. BTW after upgrading to 10.4.7 it seems to moo more and heat less, but I could be imagining things. It doesn't bother me that much since the mooing is not so loud so I only hear it when everything is silent around me. I don't think Apple will exchange it because of the mooing, they will probably say it is just the fans and that is normal behaviour. But you could give it a try, who knows.

    I think the moo is the fans operating at a low speed.

    well with the AC plug plugged in and firefox + itunes running it hit 60-65 pretty easy. Im just worried that the mooing will get annoying when i'm at school and trying to study as I like complete silence.

    The moos are the fans turning on and off. Some people report that resetting the PMU solves the mooing, but some report it gets worse, so be careful. There is a widget named Moofix or something like that that "fixes" the mooing by keeping the temp higher than 65C. I don't quite remember the link now, try google.

    Why would you want the to keep the temp higher than 65C? You want it cooler not higher.

    Question is, some Macbooks idles just below 65C. So when running light tasks, as rekki said, just safari and itunes, the temperature gets just a little higher and the fans pops in and out - hence the mooing. The widget I mentioned try to keep the temperature just a bit higher by using up some CPU time, around 67C, because then the fans keeps on running constantly, albeit in low speed, and this is much less annoying. It would be nice if you could actually cool the CPU down a few degrees, but that is somewhat impossible unless you want to mess with undervolting and such.

    Well, I looked around in Apple Discussion on this and found something interesting.

    That's interesting. At least people who get really desperate because of the mooing can fix it themselves by exchanging the fan.

    Mooing affects only Macbooks, MBPs are more affected by whining (while I think heard of Macbooks that whine as well).
