Seriously, I have heard people mention this, but I use a RevA 1.6ghz 17" at work, (I am using it right now), and no matter how hard I thrash it it has NEVER EVER made the slightest…

I'm using a 1.8Ghz iMac at work with 1 GB of RAM and for normal, non-taxing purposes - web surfing, writing, etc. - it's utterly silent. But when I play Snood (probably the least-t…

I don't want to go so far as to say the fan noise problems have been fixed, but the difference between my Rev.A 17" and my new Rev.B 20" is astounding. The 17" emitted a terrible …

Mine sounds like a leafblower, even on automatic. I guess mine is faulty and a rev.a board. I'm not sure though. I don't know if they have fixed it on the newer iMac's.

I don't have an older rev A to compare it to but my 20" rev B seems pretty darn quiet. Just sitting in front of it you can hear the "whoosh" of a fan but from 5" away, you can't t…

Screamingfit, what about when you do processor-intensive stuff? Any noticeable ramp-up in fan speed?

I'd like to hear more from Rev. B owners as well.... I'd be more likely to consider an iMac if it were very quiet.

Totally friggin' cool if this is the case. To the people who are posting about the (lack of) noise their Rev. B iMacs make.... How much background noise do you have going on that …

Are settings for performance set for automatic or highest?

I'm going to wait a couple of months and see if anybody posts obout overheating or power supply problems before investing in an iMac.

I live in a VERY quiet area. All I can usually hear are birds chirping outside. Though I was playing loops through Live, I did have the volume turned to one notch above off (if y…

Jan- I actually bought a rev. A ultimate on May 1st, then found out about the Rev. Bs coming out two days later, so I brought it back to the Apple store and they upgraded me to th…

I just got a new 20" 2ghz - and yes it IS noisy, no loud or whining noises as described for the older ones before but a constant airflow, simmilar to the noise of a ventilator. The…

I've had a rev. B 20 inch for a week or two and it's very quiet. I haven't had any of the problems associated with the original models. PeteWK

I've got a 17" 1.8ghz, and you can definitely hear the fan on the lower left. From the second you push the power on button, you can hear it, and while I'm working away, if there i…

Bought the 20" model yesterday, it developed the whine tonight. It's not that loud, but it's an annoying pitch. Maybe it always had it, I've had iTunes on the whole time I've used …

take your palm and cover up the bottom left side of the iMac, no, it won't cover your left speaker, it's a little further right than where the buzzing is coming from. So yea, if y…

reply to Yi Chen: I just got also a 17" 1.8 imac at work, true there is a buzing noise I don't hear with the 20" (see above) but it is not very loud. But hey!!!! DO NOT COVER TH…
