Cooling Computers with Tiny Jet Engines

`The computer servers that fill huge data centers are producing more heat with every new generation of processors. It’s a problem that’s sending engineers on a search for cooling fans that are both small enough to fit inside ever-smaller server chassis and powerful enough to dispel increasing amounts of heat. At Hewlett-Packard, they’ve found one answer in an unexpected place: model jet airplanes. [..]

The prototype HP fans are built from sturdier, more reliable parts than today’s computer fans, according to Vinson, and they deliver air with enough force to cool the smaller, denser, and hotter servers on HP’s drawing boards. “They literally blow you away,” he says; “it’s like picking up a leaf blower.”‘
