Coolant fluid came today...
So starting to do the fittings...
My planned loop would be:
Bay res -> Pump -> 7990s (parallel) -> 2x120 rad -> 240 rad -> CPU -> back to res
I did it this way cuz, even though there'll be more tubing, I think this would be the optimal configuration for cooling the quadfire 7990s without impacting the CPU.
Nice and reasonably neat (so far)
Bay res with QDC. This was what I originally wanted to do, but when I inserted the res, I couldn't use the QDC without first taking out the res from the 5.25" bay. So back to the drawing board.
Final loop configuration. I decided to mount the QDC, one on the CPU block, and 2 on the EK link. I put 2 on the EK link so it'll be easier to remove the GPUs if i ever decide to upgrade them.
Filling the loop and testing...phew! No leaks (yet)...
1 word. Headache.
PS: I'm not an expert with EK DDC pumps (my last pump was a DCP 2.2 lol). But the pump shouldn't be clicking right? I've made sure there isn't debris in the loop and flushed the reservoir...twice. Should I RMA it?
