Workers! If your office space sounds like the inside of a wind tunnel from the incessant hum of all the PCs surrounding you, lend me your ears.
A small manufacturing company recently started shipping a new kind of PC case that emits almost no audible noise whatsoever. Its components stay cool without the need for fans of any kind.
To research this technology, I flew to Los Angeles to interview executives of Zalman USA, the American headquarters of the company that makes the new case. I also visited a computer store in a suburb of Portland, Ore., Cool Tech PC (endpcnoise.com), which Zalman officials confirmed is the largest U.S. reseller of their virtually silent cases.
If PCs are the noisiest things in your office, this new enclosure may save both your hearing and your sanity. First, we need to understand a little bit of history.
