|The setup is more or less a dryer exhaust working in reverse. The sub-zero outside air is sucked in through a filtered inlet attached to a window insert. On the other side of that insert it's then run through dryer duct into the PC where it keeps the machine running at suitable temperatures. The "spec" also calls for a damper to be installed somewhere, but the guys at Hack A Day aren't quite sure where the creator implemented it (they recommend a servo-controlled damper).|
Mods, I'm sorry if this in the wrong section. I didn't know whether to put it here or in Tech & Science.
