Rock on man!!! I have a chassis fan for a computer and its connectors are cut off. I've been wanting to find a use for it, but you beat me to it. Thanks!! Also, is there a way to make the fan detachable so that you could just fill the bucket up a little and freeze it?

or you could just put the fan in the frezer too

Easy, just add a quick 2 conductor disconnect like this:

You could also easily add a SPST switch so you have the option of shutting the fan off whenever you want.

Also, a easy modification for better cooling would be to suspend the ice-pack locating it the middle of your container. Create a small intake opening to draw ambient air in ABOVE the ice pack then creating the exhaust opening BELOW the ice pack. Cold air sinks.

Yeah, but what if the air is really hot? You'll just be blowing hot air.
