IBM licenses water cooler to Panduit

IBM has licensed its server water cooling technology to global networking and electrical manufacturer Panduit, to help widen distribution of the technology to server rooms and data centres.

The deal covers IBM’s Rear Door Heat eXchanger water-cooling technology, and will increase the profile of IBM’s CoolBlue portfolio of technologies, said IBM.

Originally designed specifically for IBM server cabinets in 2005, the Rear Door Heat eXchanger is a five-inch deep cooling door that uses chilled water to dissipate heat generated from the back of computer systems.

The design of the Rear Door Heat eXchanger requires no additional fans or electricity, and has shown to reduce server heat output in data centres by up to 55%, said IBM.

This means firms can reduce their air conditioning costs in the face of spiralling heat levels generated by ever-faster processors.

According to analyst Gartner, water cooling is significantly more efficient than air cooling, because water can carry 3,500 times more heat than air at sea level.
