I'll start off by stating that this isn't so much of a problem as something that I am confused by. My Dual 1.8 G5 in it's stock configuration first ranat around 87ish degrees on the MLB MAX6690 AMB, whatever that is, while sitting under my desk. I then moved it to the top of my desk where it immidiatly started running at 93 degrees. I just added an extra gig of RAM, and it is still on top of my desk but it runs at 84 degrees... My question is...why would adding an extra gig of ram cause the temperature at a certain location to INSTANTLY drop by 9 degrees? Just curious. The drive bay still runs at around 84 which is in the middle range of where it has been running so I doesn't imply anything about not reading/writing from the hard drive b/c of more RAM...confuzzled. Thanks for any thoughts. Jay Oh, and one more thing... The fans are loudish. Not that I didn't expect it, and I'm not complaining, just it is noticably loudish, probably b/c I'm coming from an iBook .
