fans
I have 1 ,1.5'' sq. 12volt fan(from radio shack-cpu cooler) mounted in my invder.I leaned it between the visor post and the forehead piece,over the jt logo.screws in the bottom holes as spacers ti keep it tight to the post & screws thru the top holes(thru the mask)to keep it in place.Tape on the sides to seal.This is the reason I posted.Its powered off 1 9vt mounted on strap.Sucks air like hell and the battery seems to last 4ever.Oh and I enlarged the vent holes a bit directly under it.
