Hitachi provides liquid-cooling system for HP machine

Hitachi will supply a liquid-cooling system for HP's xw9400 Workstation.

Hitachi will supply a liquid-cooling system for one of Hewlett-Packard's (HP) high-end computer models, reducing the noise generated by the machine.

The new cooling system will be used in the HP xw9400 Workstation and should benefit power users in scientific research, manufacturing, oil and gas exploration and digital content creation, HP said. The workstation contains an Opteron processor from Advanced Micro Devices.

Hitachi's liquid-cooling system moves the fan found on the CPU heat sink in a typical computer, putting in on the computer's chassis where it can create more air flow while running slower and quieter. To transfer the heat from the CPU to the chassis fan, Hitachi relies on the high heat transfer capacity of the liquid cooling system.

The system includes safety measures to protect against corrosion or leakage of the coolant liquid.

Hitachi has already offered a liquid-cooled laptop and its technology has been used in other desktop and server products. HP claims to be the first manufacturer in the U.S. to offer Hitachi's liquid-cooling system in a workstation. Early last year, HP began selling a liquid-cooling system designed to cool rack units.

The move to liquid cooling comes as the increasing performance of CPU, graphic chips and other components in computers demand more power and in turn generate more heat. Hitachi expects the trend toward increasing power requirements will drive demand for liquid-cooling systems, particularly for applications where high-performance and quietness is important.
