I thought so...
but how could i put an led in there,
I think i would need an 100 ohm resister (correct me if i wrong) but then i don't know how to step the voltage back up, or better to 12 volts? |

| Add a 333 ohm resistor after the fan, then put the LED, and run it back to the power supply. This way, you dont need to use an amp, and the light is only on when the fan is. I can really see the point of haveing a light that is on all the time, unless it is to check the power supply, or just for looks. |

| how do they work cause when you shot it wont all pressure from the explsion break the fan or is there something that iam not catching on to your concept. |

| Pressure on the fan is pretty equil on all parts, so in most places, the net force is 0. Imagaine a mall peich of sheet metal in the chamer. When the gun shot off, nothind would happen to the metall, because both sides of it had equil pressures acting on them. same thing with the fan, only it isnt flat. |

| Once again I am wondering if this is an ignitionless fan like a bilge blower. Otherwise it can cause a misfire. |

| a computer fan has a brushless motor and will not create sparks |

| btw make sure you put the fan in facing the right direction (blowing toward the barrel) because i definately put mine in backwards and the fan blade blew off and broke etc. yet another 20 dollars wasted |
