Hey, shut up lol, i was temped to take my mossberg 12 guage to that poodles head the other day, f$#king crapped on the carpet when i was dogsitting it.
But ya, i got another fan out of another power supply and got a power cord with a box on it INpute-110v, output 12v 300mah! finaly i got a fan, moves alot air too, i started to get cold, had to unplug it

Those Radio Shack fans look like DC fans as well, there is most likely an AC->DC transformer (one of those "wall bricks") that does the conversion.

I have one just like that - it's 120VAC and it works fine.

Shit happens!
Thats why i went and bought another fire extinguisher, everyone should have one around no matter how experienced you are, hell your cat could knock something over and start a fire, and at the track they should always have them, i see a lot of people that run nitro filling there cars with a smoke in one hand and a bottle of nitro in the other???

What you just did here was, pardon me, pretty stupid.
First off, the fans in a computer case are 12V DC, which means that the electrons move in one direction only. Positive is always positive, negative is always negative. Your household current is 110V AC, which means the electrons constantly change which direction they move in the circuit (cheaper to mass-produce than DC).
So, not only are you using electricity that's 10 TIMES the voltage and 6 TIMES the current, which is about 60 times the power you need for this fan, you are using two different types of power. A lightbulb wouldn't know the difference between DC and AC as long as it got the correct voltage, but an electric motor sure does. I'm not surprised you had a fire.

sheesh, give the guy a break, he learned his lesson and got a working home made setup all at the same time.

give him a break? give him a fire extinguisher. well we'll hope he wont be screwing around with stuff he doesnt understand anymore.

just like any of us when we took apart our first lawn mower engine when we were 8 or 9 years old just to see how it worked.....
