Hitachi will provide its newly developed Liquid-Cooling System for the latest model of AMD Opteron-based workstations by HP. With the increasing performance of workstations and increasing capacity of memory chips and other components in the workstation, heat dissipation today is becoming more of an issue. Hitachi developed the Liquid-Cooling System to significantly reduce heat and noise typically generated in high-performance workstation applications. Hitachi liquid cooling provides an acoustic improvement for idle and CPU max load states, as well as a lower pitch tone that blends easily into background noise. This is made possible by the removal of the CPU heat sink fans and by implementing a higher air flow chassis fan for liquid-cooling, utilizing high heat transfer capacity of the liquid. The new system also provides reliable and safe countermeasures with high control of liquid permeation, degradation, and corrosion.
