It has now been about 2 weeks since i've finished this project and in that time I got 4 more sensors running. Still not sure why they weren't working in the 1st place or why they all started working at once. For starters the drive bay sensor and 3 others from the back side were giving "general...
Replacement RAM from OWC arrived a few days ago and all seems to be going fine now. CPU A's exhaust fan was spinning at 100% for some reason but a reset of the logic board (little button below the RAM slots) fixed that.
For the coolant I used clear EK Cryofuel. For repasting all chips I used...
Thermal calibration passed today after 15 min. When running the other tests all 16gb RAM failed at the pattern test. Take it that means it's all bad? After several attempts it was able to boot to Tiger desktop once where I connected to my wifi and set the date/time before it froze (no checkstop...
Don't know about non-conductive but i'm using clear EK CryoFuel. It's non-corrosive, anti-microbial and is great for thermally demanding PCs. Why clear? Wanted to see how much sediment was left in the loops... and it was on sale.

Not really sure. Tried rotating, shaking, and tapping it on the table and nothing. It's so weird since all the individual parts flow freely. The last time I flushed the rad was when each side ran clear for a day.
How much flow are the 2 pumps supposed to have? I think the DDC pumps are more...
Not sure if this is normal or not but when the components were separate (block, radiator, z tube) the flow of fluid was quite strong... almost too strong. However, when everything it put together there is "ok" flow and slowly goes down to a constant trickle (both directions). I know for a fact...
Did a test fit of the clamps I got (same style that were on there) and it looks like they could tear the softer silicone tubing in the future. After bending back a couple nails and slicing my finger open I managed to get short strips of the 3/8 tubing around all 8 connections. These fit super...
A little update. Got a real pump for fountains at Menards. It was strong enough to cause the radiator to vomit out crystals and other debris after another ultrasonic session. All parts flow freely and clean now.
The tubing on the bottom for the copper blocks has been removed revealing some...
Deciding to go on I removed the pumps to begin flushing the radiator. The first thing I noticed is what appears to be corrosion from some leakage on 1 of the blocks (both CPUs came off with no signs of corrosion). When everything is done I'll have to run fluid through that side for a few days...
After leaving my G5 quad project sit for a few weeks I finally cracked open the LCU. Got maybe a combined 5oz of fluid out of both loops and hope the rest will come out while flushing with external pump and time in an ultrasonic cleaner. I noticed the "Z" tubes have some kind of rubbery/plastic...
