I'm currently using a Radio Shack computer fan (cat#273-240) in my A'Sharad Hett Tusken Raider Mask's mouth to draw in air. It runs off of a 9 volt battery and has a switch to kill the circuit. I've always wanted to make it more powerful, especially now that I'm going to CIV. Any suggestions on how to give a little more oomph to this puppy? I understand that it may mean I sacrifice battery life, but that's not an issue.

I use 1-2 squirrel cage fans in my TK helmet. They seem to move a lot more air that a typical computer fans. You can find them on that e-auction site. Sometimes they are also called biscuit fans. They are 12v fans, but can be run off a single 9v battery. Hope that helps.

I was looking more for a way to boost the strength of what I have now, as the open fan design lets me talk a little more clearly and kinda distorts my voice.

Fan's @ 12v...

You're really not going to gain any extra benefit from another 3 volts worth of power. You could use a power source stronger than 12v, but that only serves to burn-out the fan, and batteries stronger than 12v can be dangerous when worn on your person.

I will offer 2 suggestions:

1. Turn the fan around. It serves 2 purposes:
a. Explusing air out the muzzle still generates a cooling effect
b. Shooting air out your muzzle also means that your exhaled carbon dioxide does not blow back at you.

2. Focus your attention toward finding a 9.6v RC car battery w/ 1600 or more miliamps (I've seen some w/ 2200). The more miliamps you have, the longer the fan runs. I've done a full day @ C5 on a single battery.
