Information about LCU/heatsink cooling
A friend of mine has an early 2004 dual 2.5 PCI-X G5 and we were wondering if we could take off the LCU *liquid cooling unit* and swap it out for regular heatsinks. Understandable that the fans will run a little louder, but it will also preserve the logicboard and PSU from being zapped with coolant. Could this be accomplished and then re-calibrated with the AHT 2.5.8 CD?
The answer to my question is yes. I bought a dual 2 GHz AGP G5 due to intermittent power issues, so i swapped out the 600W ACBel PSU for my Liteon 600W PSU and i ran the dual 2 GHz cpu's for a couple of weeks. Then today i swapped out the 2 GHz cpu's with the 2.5 GHz AGP cpu's and attached them to the heatsinks with new Arctic Silver 5 compound, and ran the 2.5.8 AHD disc and the thermal calibration passed. Now i have a dual 2.5 GHz AGP G5 running on air so no more LCS units for me!!!
Using Temperature monitor, my cpu's idle around 47 to 50ºC. If it goes over 65ºC then i hear the fans slightly. Then it drops back to idle.

No badge, just a true answer. That's what i am seeking.
Two hours of web searching on this netted nothing on swapping out. I don't see why the AHT wouldn't work or the Apple.Service.Diagnostic.2.5.8
in case anyone was wondering where the info went, my site was taken offline and moved to a more secure server. the new site link can be found here @ http://tinyurl.com/jg398v5
Can you perform this air cooled mod with a late 2005 issued G5 2.5GHz DC using the heatsinks from either a 2.0 or 2.3GHZ Dual Core G5 PowerPC?
