Chosen Solution
Seeking a replacement for my PowerMac G4 DP, I have decided on a PowerMac G5 2.7GHz DP Quad core. I have been informed that Delphi and Panasonic manufactured liquid cooling systems for this machine - Delphi’s being dangerously unreliable. How can I tell which lcs is installed without dismantling the machine?
As I understand it the problematic models were the G5/2.5 DP (PCI-X) (June 2004) and G5/2.7 DP (PCI-X) (Early 2005)- aka PowerMac7,3- which were prone to leaking. So unless there’s some sort of proof that the cooling system was replaced with the type from the late 05 avoid these models like the plague they were. The G5 “Quad Core” (2.5) (Late 2005) - PowerMac11,2 - used a liquid cooling system that was substantially improved and better “sealed” to both reduce the likelihood of leaks and prevent leaks from damaging other system components. If this answer is acceptable please remember to return and mark it.
Also Delphi made both coolers in the G5 Quad 2.5Ghz , Delphi for the single and Delphi/Cooligy for the double pumper. the Panasonic was only in a select few of the DP 2.7GHz machines. The Quad was only ever a 2.5GHz with two dual core CPUs.
