While I won't say this is the loudest machine I have ever owned, my new 1.25 (which should be fine to compare by) is certainly the most irritating to listen to. It might be just my machine, as friends who work at an Apple Store are surprised by this; my machine makes a high pitched sound a lot of the time. It's never really audible when I am playing music or a game, so I almost never hear it. However, the frequency of the sound is quite annoying.
Then again, I have a desk that encloses the machine to keep it out of the way. The enclosure may amplify the sound and make it more apparent.
BTW - I wouldn't give up the performance for any amount of sound!
Hope this helps,
Dan
