NEC reveals phase-change CPU cooler that uses 80 percent less power

Posted on Monday, May 03 2010 @ 16:01:37 CEST by

NEC has reportedly developed a new eco-friendly cooling solution for processors that uses 60 percent less energy than a watercooling solution and even 80 percent less than an air cooling system. The new phase-change cooling technology will be rolled out for data centres sometime next year, the company claims the system can cut their total power consumption as a whole by more than 40 percent.
The core of the system is a liquid chlorofluorocarbon (CFC) substitute, which circulates around the CPU to draw away heat and has low greenhouse effects.

NEC says the refrigerant begins boiling at around 50C, changes into vapor that absorbs the heat coming from the CPU, then flows through a tube, and is cooled by a fan in a radiator before changing back into liquid. After that, the process in the closed loop starts again.

According to NEC, the cooling fan doesn’t have to work as much as under other cooling systems and needs less energy. The company also claims its system is around 70% cheaper to produce.
