Computer/axial Fans & Laptop Power Supply

For this you're right.. Getting tech, wire is frequency rated..

You guys are great. I'm glad I posted my "dummie" problem. Be sure to check out your local Freecycle group!

So, I'm after 3 adapters, right?
> 1x 12V/2A+ for the two (.30A) fans pulling from one end of the cool tube
> 1x 12V/1A+ for the other (.30A) fan pushing from the other end of the cool tube and
> 1x 12V/1A+ for the (.30A) circulation fan (so it can run 24/7).

try to stay under 3/4 of what the supply is rated for.your 2 fans drew about .6 amps together so a 1 amp would be fine, for a single .3 amp fan,a supply that puts out 5-700 milliamps would be fine also. going bigger wont hurt if the price is right tho.

I never did plan on soldering the wires together but instead, I read last night on another forum about how one could use a soldering iron to melt/strip the insulation from those tiny little fan wires.

a lighter works just as good -dont overheat it,just pass it over the flame & U should be able to pull the jacket off w/ your fingernails.

Thanks, mrmadcow. We'll see what goodies come in the freebie box and go from there.

I dropped by 2 help, but looks like it has already been explained.. So have you got your cool tube fans spinning yet?
