It's really cheap. A $2 CPU fan, four number 8 bolts, some leftover aluminum strip, some wire and some black paint.
Just screw it in place and power up for inexpensive cooling. I have a battery powered fan that runs on D cells but this is way better, cost way less (my battery fan was $6) and the battery powering the fan is charged from the sun.

Push comes to shove, my o2cool fan can still be used when there's no juice in the solar batteries.

I've used these for various applications. They work fine in very low loading situations but they are very low amp units and will not push much air. For that matter in a negative pressure situation, they might even blow backwards. ::)
Weird. I responded to this but it's not showing up...
Anyway, I find them pretty good. They shift more air than my $6 2D powered desktop fan. The aim is partly to assist my extraction fans by circulating the air a bit.

Here's a CPU fan setup for laughs. MY hillbilly fan on top of my fancy door desk. LOL

Nothing wrong with that. I knew a guy who had a scaffolding plank pinched from a builders yard placed across two rusty filing cabinets he pulled out of a skip as his office desk.
