Any Heat Issues with 2.4GHz vs. 2.8GHz Extreme?

Was at McStore and they didn't seem to know of any heat concerns

Because there aren't any! No houses have burned down or no one has been killed because of a hot iMac.

Was at McStore and they didn't seem to know of any heat concerns. ... oh, and the new machine doesn't sound like a snowblower all the time either.

Were the previous "white" versions loud? (I've heard some "snowblower" machines, but not with iMacs)

Were there any heat problems with the previous whites, since they didn't have the heat-radiating aluminum? I'm leaning toward getting one of these, either an old-20 or old-24, and (since my room isn't air conditioned) heat is a concern.

Are the new machine cases aluminum both front and back, or only front?

A house doesn't have to burn down for a component to fry or have a shorter lifetime because the fans aren't doingtheir job well. THAT is the question - not burnin down the house.

I'm referring to my white G5 machine. I'm still using it a bit to do 'busy' work, but it's very loud compared to the new machines, which are silent. I'm not sure what the fans are like in the white intel machines, which is what you would be looking at.

The white machines have a 'plastic like' case, which didn't get as hot. The new aluminum case does get very warm to the touch, but it also acts as a better heat sync...

But I've used both machines in my 90 degree apartment, and no neither burst into flames.

I don't believe for a second that Apple would build a Mac that runs too hot. My 2 cents - it's a non-issue. If you need the speed, get the 2.8.

Guess you never heard about the early MBPs and MBs.

My white iMac at work gets so hot it burns your finger if you stick it in the vent at the back, but I couldn't give two hoots.

Something is wrong with your white iMac.

No, nothing wrong with it. Stick your finger in there as far as possible and hold it for 30 seconds - it will get quite painful!

Data is useful. ...
• Is this similar to the temps others are finding?
• How do these temps compare with those for older (white) 24" and 20" ?
• What temp-ranges are considered OK for different components? i.e., How much do various temp-increases decrease the life of different components?
• And how much does the internal temp increase when an iMac is run in a warm room? [ranging from 75 F to 93 F (24 C to 34 C)]

So, is there any data about internal temps of the old "white" and new "aluminum" computers, both 20" and 24"? Craig
