Incubators?

Here's a little tutorial I put together for a DIY wine cooler incubator.

Old wine cooler + heat tape + thermostat of your choice.
In total mine cost around $150 and holds 3 6qt tubs.

I have a question... Or rather a few ha How exactly do you hook up fans in the incubators? I've heard you buy computer fans off line and wire them??? But how??? Do I just get a random phone charger snip, strip and connect them? Will the fan come with wires?? What fans do I get? If I want two fans do I need two chargers/ power cords? Sorry for all the questions.. :/ I just want to make sure I plan and do it right. I already gutted the mini fridge.

Thanks to all!
