I have question reguards to this. I too have a dp 2.3 g5 powermac. In looking at the picture, for the underside there doesnt look to be a way to maybe mount some type of chipset cooling fan? Kind of like when some pc motherboards had a little fan on the chipset for cooling purposes. Also I remember reading somewhere here about by now due to age of g5s that its best to re-do the thermal paste. Would it also help to do on the underside of the mb? I dont think its an issue since I'd imagine the heat pipe area would have adequate thermal tape or something?

Im just asking this as I dont currently have any issues yet on my g5. But if there is some precautionary steps or something to help avoid these inevitable problems I'm all for it. The only other thing i have done so far is make sure to compressed air the unit regularly, and made sure to put in 1/2 the max ram it can take now, and finish it out in the future. In other words making sure to not touch the mem slots any more than i have to.

Thanks in advance.
