I currently have 53 XFX R9 290's and am looking to watercool these cards as they obviously put out lots of heat and are loud. I'll start off by saying I've never water cooled a setup before, but I'm very handy and can do plumbing and electrical. I have my current setup on 2 dedicated 50 amp circuits at 240v.
Currently I'm considering the EK Water block with backing

I'm thinking of running a 1" supply line that then branches to 3 systems of 4 gpus each. Each set of 4 gpus then would be cooled in series which then would dump back into the output line (heated water) into a 1" tube that runs to the heat exchanger outside.
Input line 1", then splits into 3 separate 1/2" lines which feed 4 gpus in series, which then dumps back into a 1" output line. I'd need to run 4 separate heat exchangers and 8 pipes total for intake and output lines.
The other idea is to run a massive 2.5 inch supply line and output line and right before it gets to my computer rigs would be to branch the supply into 4 smaller 1" lines to feed each gpu set in series. This I think is better as it requires less plumbing. The only down side is if something happens to the main line, all the gpus are going to overheat and hopefully thermally throttle back.
So for pumps, I was thinking of either going with car intercooler pumps since I'm pretty familiar with these. And then using a water to air intercooler or a car radiator to dissipate the heat outside.
Current pumps I'm considering

or maybe a Mezeire electric water pump. I'm familiar with these 12v pumps and they work great in high heat automotive environments. I don't have any experience with well water pumps, but I think this may be another solution. Either way the entire cooling loop is about 150 ft long so for the 12v pumps I might have 2 run twin pumps at like 75 ft or so to keep the flow going and cause less stress on the pumps.

or I'll find a big truck radiator. Ideally speaking the radiator would want to be able to dissipate 10,000 watts of heat.
