Fan on I Mac G5

Question

There has ben a lot of discussion and talk about the possible overheating problems with the G5 I Mac.
I walked into the apple store the other day and had a look at the same mac as what I have. It was dead quiet. The fan didn't even come on. My fan runs the whole time and varies in speed once I wake it up.
I wouldn't say there is a great deal of heaton the machine but there is definnitly a lot more noise on my machine as opposed to the one I looked at in the store.
Could someone plese elaborate for me before I pack up the machine and ship it off to the repair centre. It is quite a way from where I live..
Many Thanks
Dave

The fans do come on, you just dont hear them as much with the redesign Apple did on the iSight iMac G5. I had the Rev A and now have the Rev C one and lemme tell you, there is a big differnce between the two.
It runs cooler, more quiet, faster (using a bigger processor and faster new ram), and more reliable ( Apple redesigned the internals of this machine learning from the first 2 incarnations of the iMac G5. Most of the heat generating internal components have been moved to higher postions within the case so as not to "bake" the rest of the motherboard.(which was a major problem with some of the rev A and B machines.))
