Bitcoin's biggest miner, BitFury, says it is launching the world's largest two-phase immersion cooling project.
BitFury CEO Valery Vavilov said in a statement:
Phase one is on track to achieve a power usage effectiveness (PUE) score of 1.02 – meaning that for every 1.02 watts the centre takes in, 1 watt is transferred to its equipment. According to a 2014 survey, the average reported by data centres is 1.7.
With a deflated bitcoin price and increasing competition, running costs are more important for miners than ever. While power is often the biggest overhead, cooling equipment that runs 24/7 is another.
In an interview last April, Allied Control's vice president of engineering, Alex Kampl, told CoinDesk immersion cooling, while costly, is a perfect fit for the bitcoin mining industry:
The process works by immersing hardware in a liquid with a very low boiling point. Once heated, the liquid will evaporate, pulling heat away, then condense and drip back into the tank. 3M claims it can reduce costs by 95%.
Fluids aren't the only choice for industrial-scale bitcoin miners seeking to cool their equipment, however.
In September, KnCMiner opened an 18,000-sq ft facility in northern Sweden that keeps temperatures low via Arctic air pumped in by giant fans. It is said to run on Europe's cheapest electricity.
