iMac G5: Rev. A vs. Rev. B

[gregorydanger]

Just a question.

A while back I got my hands on a rev. A iMac G5 and ended up getting rid of it because the fan just would not shut off. I know that sounds completely stupid but trust me, it WAS ridiculous. I was running the OS in "Reduced" processor mode (as opposed to "Automatic") and all I'd be running was Safari and the fan would just start going crazy. I can't stress the keyword "loud" enough.

Anyways.

Other than that I loved the machine. If it hadn't been so loud I would've held onto it. I've heard that this problem has been fixed in the most recent release of the iMac (Rev. B) but I just want to know if this is true before I went out and bought one. I doubt that I'd get a straight answer talking to a "genius" at an Apple store so I figured I'd just ask here.

If anyone has some insight I'd be very glad to hear it. Thanks!

The Rev B's in general are supposed to be far quieter although some are still apparently quite loud...

Also your Rev A was robably one of the un-lucky one's which was very loud as not all rev A's were loud....

If you want a quiet iMac G5 the Rev B's should be fine and if it is loud im sure apple will swap it over under warranty..

ShadOW 😱

I bought a revision B iMac G5 17" and returned it the next day, because of an incredibly annoying buzzing sound coming from the bottom left hand side, facing the screen, which kicked in whenever I actually did anything on the machine. I replaced it for a 20" version and the difference is like night and day. Quiet, fast, beautiful screen etc.

Sounds to me more sensors that are off! Just like the rev A of the dual 2.0 powermac...

I appreciate all of your responses.

Generally, I find it a little disheartening that Apple would release a system that you basically have to buy to find out if it'll run properly. I understand the issues regarding the G5 processor, particularly in the iMac, but you'd think that they'd take a few extra steps to prevent machines that don't run up to par from getting out there.

Regardless, I think I'm going to pick up another one (base 17" model) and hope all goes well. If I have problems I'll just return it. Again, thanks for the tips!

From what I have heard and personally experienced, the Rev. B models are hit and miss when it comes to the noise level. While some state that their imacs are whisper quiet, my Rev. B 20" imac had a "whirring noise" that would get louder as the computer got hotter. It became so annoying that I ended up selling it. It was a nice machine but was too loud for my taste.
