Apple G5 CPU phase exchange unit

post #1 of 7
Thread Starter 
I wanted to fire this thing up and use it for something. It's probably not powerful enough to do much more than keep my can beverages cool, but it's a neat conversation piece, anyhow.

The problem is, I have no idea what the pinouts are on this thing, just that it runs off 12 volts according to the sticker. ANY help would be appreciated! Sorry for the crappy pics, BB phone rolleyes.gif

I don't think thats a phase change unit. If I remember correctly its just an all in one LCS. What you have there are just basically 2 Delphi/Laing pumps that you would need to pinout.

Oddly, the unit images are not that of the Apple G5 Coolit unit. It is actually the Panasonic unit. The pumps run off of a proprietary PWM controller. They are not the Laing DDC either.
