Hey, I live in minnesota and it routinely gets way below freezing in winter. I was wondering if I could harness this cold air by funneling it through a window and into my system. Would that be very safe? Does anyone know at what point cold air can be a problem to computers.

Overclockers routinely cool their CPU's, GPU's and chipset's with LN2(Liquid Nitrogen)or Dry Ice and sometimes mixed with solvents to lower the temp further to ~ -195C. Hard-drives could be a problem at extremely cold temps, though, so i would keep them sheilded from the cold air(as much as possible). The other problem with plumbing in the freezing outside air is condensation/dampness. It would be hard to control that from entering your case, and could wreck havok with your hardware. Good idea, but not as simple and straightforward as it would seem. GL :)

Exactly what Tanker said: Condensation would kill the system.

Its a neat idea, and could be worked, but not easily. When I lived up north, I used to leave the window in the computer room open a crack to keep the ambient temperature down. Ambient plays a critical role in system temp for air cooled systems.

If you really wanted to play with this, there are a couple of things you could do, based on a heat exchange system. With heat exchange, you are not actually exposing the system to the variable elements.
The easiest way would be to take a retail liquid cooling system and extend the lines to place the radiator outside. Basically a "central cooling" system for you computer.

Theres some other ways you could play with it, but they get more complex, consuming more time and money.
