cool mask fan mods people. I've been working on a couple different ways to setup your fan system. Currently I've put fans in pmi masks (forgot which ones), nVader, and just did my Proteus. I got a 40mm x 40mm 12v fan, toggle switch, and run it with a 9v and 2 AA (equals 12v). I keep my batts in my harness pocket and run a short wire connected to a 9V batt clip, on my mask I have 9v clip to connect to. I'll post pics later so you'll see what i mean. any Q's let me know
P.S. dont forget to heatshrink your connections!!!
