This will not work on 2x Asic miners will support only one , i belive theoretically it could but you would need 2 loops as if you would push hot water from one miner into second the second would overheat.
I also thought that connecting ASICs in series would be a bad idea.
Where I saw pictures of similar cooling systems that were made by garage craftsmen. It turned out much cheaper from an old car radiator and a fan.
