Lenovo introduces new water-cooled server technology

Lenovo has introduced a new high-density server “tray” for high-performance computing (HPC) environments with the newest generation of water cooling technology it co-developed with a German HPC firm.

Unlike your typical water-cooled system, where the water is chilled almost to a drinkable state, the ThinkSystem SD650 high-density server tray — so called because of its design and shape — is designed to operate using warm water, up to 50°C, or 122°F.

There is a mindset that CPUs have to be chilled as though they were cold cuts, when Intel says they can handle much higher temperatures. Xeons can handle temps of up to 75°C without becoming unstable or crashing.

By using warmer water, Lenovo claims it will lower power consumption 30 to 40 percent compared to traditional air cooling methods.
