NISVARA
The
more powerful the microprocessor, the more heat it generates. And that is a
problem. Heat bakes components and corrupts them over time. Worse, the fans
that cool chips are not only loud, they fail often. Thus the search for a
quieter, more reliable cooling technology. Nisvara, a startup
backed by the Girvan Institute – a NASA fund set up to transfer technology into
and out of the space agency – is using materials developed at NASA to beat the
heat. Nisvara CTO and
founder John Sokol’s solution is a material made of carbon nanotubes. It can
withstand great heat and is one-sixth the weight and 100 times stronger then
steel. Nisvara makes both active and passive cooling systems. The active system
involves a liquid coolant; the passive system uses a heat sink (essentially a
piece of metal with many blades) to soak up heat and vent is away. One area of
particular appeal for Nisvara’s technology is the server market, where it could
substantially reduce the cost of operating a data center or server farm. Fan
failure is the number-one cause of server failure. What’s more, over half of
the electricity used by data centers and server farms is for air
conditioning. No fans also means less
vibration-caused tracking errors, which are a problem in the SAN/NAS hardware
arena. But Nisvara’s
immediate plans are in the PC market. The company hopes to make early revenue
by selling a high-end silent PC aimed at programmers and other who value noise
reduction. Another potential near-term market is in media production, where
silence is highly valued. Nisvara has filed
for a provisional patent on it’s technology, which is says is differentiated by
its approach to cool the entire machine rather then the chip alone. It is now
seeking the first $1 million of a $5 million series A round. Rob Chaplinsky, a
general partner at Mohr, Davidow Ventures who has been monitoring new cooling
technologies for the past two years, calls chip cooling ”an unexplored industry
that’s in need of disruptive technology.” Chaplinsky is an investor in Cooligy,
perhaps the best-known startup in the field. Other competitors include Active
Cool, Cool Chips and Isothermal Systems Research. While Chaplinsky thinks there
is still room for competition – he sizes the cooling market at $1 billion on
the PC side alone – he points out that startups like Nisvara that are still in
the research phase won’t have a working product for several years, while
Cooligy is already testing a prototype with customers.
