@Mega: Laptop fan? Nah...


...try some of these guys from the stormtrooper batalions. I'm sure they know about better helmet fans.

at the second Heroesnight in Dunedin there was a guy with HALO armor that had dualing fans in the helmet. Cosplayers know them about some helmet fans.

I think I saw a web site that guy used to use to sell custom HALO armor -- or the web site of the guy he bought it from. I thought they were laptop fans...
which guys from the stormtrooper battalions? My helmet needs are very similar to Stormtrooper cosplay now that you mention it.

Stuff like this shootout documentary on YT makes me wonder if a "superhero academy" isn't in actually a good idea... usually I consider it kind of unrealistic. Crazy.
