When did FC say anything about it? First I saw of it was from AC.
Custom Cooling Systems
We have been finalizing on our HK datacenter with our professional partner on immersion cooling. This product will be of interest both miners, and other industries that require cooling of similar hardware. Our cooling system partner built it as an exhibition house where everything is clean and shiny for investors/buyers to visit and for ASICMINER to make videos as a demonstration.
This is the earliest reference I could find quickly. I was always under the impression that the cooling partner (whom we now know is Allied Control) gained a space to demonstrate their technology and ASICMINER gained an immersion cooled datacenter. It seemed like a win-win partnership to me. I'd be happy to be mistaken, though, and learn that there are stronger connections.
