Immersion cooling firm LiquidStack launches as a stand-alone company

LiquidStack’s low-power, closed-system server-cooling technology, has caught the eye of Microsoft Azure.

Ever since Bitcoin was introduced back in 2009, this cryptocurrency has had the distinction of being something you could mine with your computer—putting your hardware to use helping the blockchain technology Bitcoin is based on record and verify transactions by solving complex math problems.

As a reward, you’d get Bitcoins. But it was a very slow process for a single PC, and the necessary component for success was a high-end GPU. One GPU brought to bear on Bitcoin could take years to find one coin, so miners started building massive farms akin to data centers but without enclosures. The result was that Bitcoin farms bought up all the GPUs, causing severe shortages and infuriating gamers.

GPUs run notoriously hot and for some time GPU cards have come with three fans on them. It is possible to replace the heat sink with a water cooling system, but The Bitfury Group, a blockchain services provider, went one better and instead used liquid immersion—putting the hardware in a dielectric fluid. It bought the technology by purchasing Allied Control in 2015, and now that division of Bitfury is being set up as an independent company called LiquidStack.

Wiwynn, a hyperscale server vendor from China, is investing $10 million in Series A funding to launch LiquidStack and its immersion product, DataTank.

DataTank immerses the computer electronics in a non-conductive bath that eventually comes to a boil as the chips heat up. The liquid boils off as a vapor that carries away the heat, but is captured within the sealed DataTank and condensed back into liquid.
