Iceotope plumbs in immersively cooled servers for first customer


Iceotope's immersively cooled server racks are now in production, and the company has named its first customer. The University of Leeds has been using an Iceotope server since December to run computational fluid dynamics models -- and to warm the radiators in one of its laboratories.

The company showed off prototypes of its unusual liquid-cooled system at the Cebit trade show in Germany last March, but took another few months to figure out how to mass-produce the aluminum server modules, which are filled with Novec, an inert coolant liquid from 3M.The Novec carries heat from the server motherboard to the module's surface by natural convection, without the need for noisy, inefficient fans. Water is pumped to the top of the rack, from where it trickles down over the modules to a heat exchanger. A secondary water circuit then carries the heat away, either to a rooftop cooling system or, at the University of Leeds, to regular domestic radiators.
