[G4] Liquid Cooled new g5 2.5 ghz

We're really talking about three heat exchangers running at the same 
time. Two heat exchangers are from the chips to the fluid, the other is 
from the fluid to the air. I know that's stating the obvious, but the 
key is: how much temperature differential there is between the two 
processors depends (among other things) on the rate of the fluid flow. 
If they move the fluid really fast, then the two processors are at 
nearly the same temperature. If the fluid moves as slow as a lava lamp, 
then the 2nd processor toasts up :)

You *could* arrange to have the plumbing done in parallel, but as noted 
in the car engine example, that gets to be a real hassle to design and 
implement.
