Hi all,
Here is what we did for the same purpose :

I must confess that those muffin fans seemed like a good idea at first, but the truth is they don't blow that much.
Nevertheless, our defogging system works as expected although it is a bit on the asthmatic side...
We need it on the ground only since as soon as the airplane is airborne, the fog quickly disappears.
FWIW

I am not finding any computer fans in your website.
Can you please tell where they are in your online store?

Most of the computer fans (at least the ones we sell for less than $10) are simple to wire because they typically have colored wires….red is always power, black is always ground, and the others are various rpm/sense wires that you don’t need to use. No need to run them through a thermostat, a simple switch will suffice. We also stock the little “grates” that go over them to direct the air appropriately (living in snow country we learn a thing or two about defrosting).
Don’t make it more complicated than it needs to be – keep it simple.
Cheers,
Stein

Hello John
I bought one similar to those, but the problem is that it has a 4-pin computer connector, and I don’t know how to wire it.
After some research, I came to the conclusion that one of the wires is to control the fan, and that control is done through the motherboards of the computer, which is not the case for us.
That’s the reason why I am asking for specific fans that other builders have successfully used, and for how to wire them.
