canada winter cooling

post #1 of 13
Thread Starter 
so with our growing coldness i was thinking i could make a pc that was cooled off the -30 temps that will come and stay for the next 3 months. theres a few foreseeable probs though. first off you wouldn't want snow blowing in your pc when it snows. seccond you don't want your house getting cold because your pumping cold air inside.

Your question is? I would crack the window open, and have the intake fan on the window side, and exaust fan on the room side. That way, your computer heats up the air as it comes in. It's a rough idea, but money and time would be the other option. Some people build custom air ducts from the outside, straight to their computer. Myself, I would put your computer outside, build a wooden box around it, and drill some holes for air ventilation. Then run the cables trough a window or something into your room. That's cheap and dirty, but it would take advatage of the Canadian winter.

Wouldn't you be worried about Chinooks? I lived near jasper for about a year and experienced those things first hand, the whole place went from -30 to +20 in a matter of hours. Everything melted, weirdest thing i ever saw, would kill your computer if you've got it running on high clocks for -30'c temps then all of a sudden the temp rising by 50'c. Although if you don't live within 3 hours of the eastern side of the rockies you probably won't have to worry about it.

I'd also go with the ducting from the outside, into your computer. Do you have air vents in your place? You could straight from one of those to the side of your computer, put a 25cm fan on the side panel, it should create enough negative pressure to suck in the cold air down the duct and all over your mainbaord, be sure to put a dust filter on it though

-30... you'd want to take some kind of precautions against condensation would you not? i mean, my PC sits infront of my window with really high CFM house fan blowing the cold air through it the open panels of the case. but outside would be pushin it without proper measures

Condensation only forms if the PC is colder than the air around it. Since the air around it is what's cold, there would be nothing to worry about.

If you had a liquid cooled computer you could include a 2nd cooling circuit for your computer with a outdoor radiator for added temperature regulated cooling.

The only thing you would change in the original cooling system is the internal coolant reservoir to a larger external reservoir (couple of gallons or larger) and add two holes in the reservoir for the 2nd cooling circuit. To avoid thermal shock you want to keep the cooling intake port as far away as possible from the 2nd cooling circuit's output port.

A 1/4" pump would be used to pump coolant in the 2nd circuit from the reservoir to the outdoor radiator and back. The pump would turn on when the coolant in the reservoir got to 70 degrees fahrenheit (using a thermostaticaly controled switch) and off at 65.

Also you would have to use a 50/50 anti-freeze mix so when the pump wasn't running the coolant wouldn't freeze in the outdoor radiator.

I havn't actualy tried this but it seems like it would work.

i probobly wouldn't make it this complex but the idea of using liquide cooling is a good one. i have an old truck radiator in my basement and a heat sink i can take a drill press to. ya i know it's a little jury rigged but hey it may work

right now there is snow on the ground and its -12 but it feels like -25 with the wind chill

pah!- way too complicated. Parsimony is key. Go get a dryer vent kit for venting the dryer to the outdoors. Go to the auto parts store and get a foam filter to keep out snow and discourage small critters. connect the duct to an intake on the case with a good ( read Silverstone or Delta ) 120 mm fan, and yer good to go!
