How to keep your window open during the winter?

[Meatball]

So, in the next month or so, things should finally start cooling off here, which will be a nice break.  With the temperature drops I'm hoping I can shut down my extra window AC and just use the cool air from outside to cool down the room I'm doing most of my mining.

The question is, how can I keep those windows open to let the nice cool air in and hot air out and not worry about any concerns with precipitation or dampness on rainy/snowy days.  There is no real overhang over the window, nor shutters to keep that out, so if there's anyone out there using outside air for cooling, how are you handling that?

I have my computer next to the window, and I live in Michigan, so I'm looking forward to the free cooling.  What I plan on doing is opening the window ~2-3 inches, duct-taping/insulating half of that, and funnel the other half into the side of my computer.  Cut-to-fit screens are optional.

Edit: About precipitation, I'm thinking of curling the 'air duct'  into a bell-curve shape, that way if any water did find its way into the duct, it would just slide back down/out.

I'm using windows at night now because it drops below 60 degrees here. I haven't given what you said much thought yet but opening two windows in different locations tends to move air around quite a bit. Unless its pouring buckets I doubt rain would get in. As the temp drops though you can probably get away with the windows being open an inch or two which will prevent snow and other stuff from coming in.

That's actually not a bad idea.
Although I live in south Florida so I only get about 2 months outa the year where it gets below 70 at night.
Can't wait till December >.<

A dehumidifier is typically a household appliance that reduces the level of humidity in the air, usually for health reasons.

Most windows have two panes, the inside and the outside pane. If you close one but keep the other one open, your rigs will be protected from the elements, and there will still be some heat exchange going on between the inside and the outside of the window. You don't need air flow, just the transfer of heat.

Would not be cost effective though as they use many amps and if they had to run often only more of a loss.

just some plywood proped open by a 2x4 creating a shield of sorts from things blowing in directly, RH is lower in the winter than the summer in general if you don't allow the snow in the first place humidity isn't going to be an issue.
