Sense even if one processors goes bad you still haft to replace both because they are together side-by-side on a daughter card of which that connects to the mother board. At the Apple store an Apple tech told me one pump failed cause only 1 of the two processors to over heat causing it to fail and go bad ruining the whole daughter card of which the two processors are soldered on too.

In 2007 I had one water pump that failed sense they r machinable water pumps I guess they don't last forever. So to anyone thats taking time of their own to read this I only hope u understand the general description of what I'm describing. To be exact my machine come with two separate water pumps (one for each chip) but the design or layout of each water pump led them both to route all water flow to one central radiator cooler (please excuse me if I'm describing any of this wrong). I have owned it sense nearly the day it was released which I guess was in early 2006/late 2005. To any and everyone that may read this post and to anyone that cares I want u to know that I own a Quad Powermac G5. 2 chips 4 cores, each core running at 2.5Ghz.

I will not go into much detail but the 2.5Ghz water cooled model was a quad core G5, it had two dual core IBM 970 processors. So please excuse me if this post of mine should be located in an different area of the forums. I really want any all knowledge that is possible to be obtained for the G5 mainly for the 2.5Ghz water cooled model. On the other side of things I can acknowledge sum truth to the matter and I'm really looking more more! 1st thing I want to say is apple made a G5 that was air cooled with an 970fx that was 2.7Ghz and while it was air cooled it was only a dual core meaning one chip with 2 cores on the die. Hey I'm new and just joined the forum, and even though I'm aware I may still be letdown by future info in this regard I'm truly excited about hearing that the G5 can be upgraded.
