canopy fans

and the converter plugs into the outlit? how do u find out Amps

It should say right on the AC/DC adapter its rating.

Safe to say with a few hundred ma I don't think you can burn the house down. There's more stray voltage in your tank than that. (Disclaimer: I am not an electrician. This is only a theory...)

I have 2 of the ultra quiet PC fans from NCIX installed in my hood (the big 5" ones). They are soldered to a standard 12V dc adapter that plugs into my Apex controller. Fans turn on with the Halides and when the water is above a certain temperature. And they turn off when below a certain temperature.

fans say 0.21A theres no adapter the last owner cut it off only wired together

Go to a dollar store (that sells things that are more than a dollar) and they often carry variable voltage wall worts. Cut off the end that is on the wall wort where it plugs into things and wire it to the two wires coming off of the fans.

Here is a link to a "how to" for you.http://www.ehow.com/how_6127007_wire-computer-fan.html

I would assume they are wired in parallel? Normally fans have a red and black wire. red goes to + and black goes to -. If you hook it up wrong it will just go on reverse direction if i am not mistaken. Any ac adapter higher than 0.42 amps should work just as long as it is 12 volts

Based on how this thread is going so far, I think it might be a good idea if you do this with someone on hand that has some experience with electricity. It's a little dicey trying to provide safe advice regarding the hookup of this nature without some photos & more details on how this rig looks at the moment, even if it is a low voltage DC job. Electrical tape is not the best way to connect wiring.

For sure. It really needs to be soldered. If you're not handy with that type of stuff, you may want to ask around.
