yes i did it. definitely makes a cool breeze. mine recirculates using a small fountain pump. not enough to cool a room considerably, but it makes the heat much more bearable than just a fan. plus it dehumidifies like crazy. pic of condensation incoming.

here is mine that i made, works pretty well. main advice would be, in fact, not just adding more ice, but basically having as large of an ice to water ratio as possible. you really only need enough water to fill the system and for the pump to be submerged. Dont fill the cooler with ice, then fill it to the brim with water. it will melt, trust me. also seal the cooler, dont leave the lid cracked like that guy. adding ports to the side or top and feeding the 3 lines (in out and power) through it would greatly slow the melting of the ice.

1. First clean and prep all parts.

2. Then remove the grate from the fan, and begin placing the copper. 4 zip ties per revolution, spiraling towards the middle. I put mine on the inside, so condensation wouldn't drip every where and so it would be hidden, so I had to drill two holes in the side of my fan. Big deal.

3. Put the grate back on the fan, slide on hose clamps, slide on vinyl tubing, tighten clamps.

4. Fill cooler with ice and enough water to cover the pump. Push inlet tubing into pump outlet. You may need to get an adapter. Place outlet tubing into cooler.

5. Turn on pump, turn on fan.

How to get parts:

If you don't care about money (I don't see how this is possible, because you're trying to make a/c out of a cooler and a box fan, but anyways) you can always just buy everything. But I got on old cooler from my dad, scoured freecycle for a fan, got a pump that was $25 at Home Depot for $8 on craigslist, and just bought the little cheap parts since it wouldn't have even been worth driving further than the store to get them for free. The copper tubing is the one expensive thing I had to buy, since people don't usually just have copper pipe sitting around, its usually in a wall or something. Plus it came in a coil, which made it super easy to slowly unwind as I put it on the fan. The moron who made a fan (just good diy a/c and you'll see it) and snaked it back and forth over the front of the fan really messed his up, I don't know how.
