Shows How I put a CPU fan in my mask.
Why?? I have thermal lens, so no issue there, but I wear glasses. The fan makes a huge difference.
Why not just buy the JT fan? they were 60.00+ when I did this mod, and I was poor. But I eventually bought the JT fan and went back to this for several reasons
1. cpu fan is quieter
2. cpu fan moves more air
3. cheapier on batteries, once a 9v is not strong enough for my electro marker, I use it in my mask ;)
4. easy battery replacement. thos damn JT fans require removal or tools, depending on which version. The cpu mod almost doesn't require mask removal to switch battery lol

Materials used:
-1"x1" cpu fan (radioshack)
-small toggle switch with threaded nut to secure to visor
-piece of speaker wire to run from front of mask to back of mask for battery.

Tools:
-heat shrink
-soldier
-soldier gun
-heat source (lighter, heat gun, etc)

I think pics show how it was done ;)
