    I've read that some people hook up small computer fans to help keep warm air in, and produce a nice flow of air.

    How would I power these fans? I have several around my house that just need a power source, I'm curious to see how you have done it.

    The fans are used for ventilation, not to keep warm air in. If they are blowing air in from outside they will also be letting warm air out.

    You need to step the power down to 12 volts. You can use a multi-power adapter and cut the end off then wire it directly.
    Something like this, from a desktop calculator.

    If you look, they make 120 MM fans with a 120 v plug on them.

    I ended up using a 120v to 9v plug, just wired it together. Works nicely
