Small notice: I will be as discriptive as i can, but this 'ible is a free-for-all type design. What I mean is, the container you use will determine the fan size, type, and amount of extra stuff/cutting you'll need. Also, this is now done This is the edit. This second fan IS be the main photo source for this project. I didn't think about writing an 'ible until AFTER i finished up. Sorry :)
Now, onwards to the meaty bits after the jump
Step 1: Materials are needed...obtain!
Obtain in one form or another the following:
1. Ice chest. You determine the size. I used a small (approx)10-inch one. Let's put it this way, i can fit 4 standard water bottles in it.
2. Cutting utensil (my cheap self used a handy pocket knife, until I have my dremel tool back, I'm resorting to caveman style)
3. Fan. Again, this is based on your needs, as well as the size of your container. I chose a set of 80mm ThermalTake fans. They are amazingly quiet, and 27CFM for the low noise is decent.
4. Freezable/refreezable products. I picked up a few refreezable icey blocks. They were a dollar apiece, how could I say no?
5. A power supply/wall wart. My fans needed 12v. Again, do I have to repeat myself as far as your personal setup will vary? Pick a wall wart that will make your fan run properly. I dug one up from an old set I had. You can probably do the same.
6. Patience, and safety! I am not responsible for you exploding, mutilating, biting, scratching, punching, or otherwise assaulting, defacing or marring yourself, or anyone or anything else. You assume your own risks.
Enjoy, and now, please continue safely :)
