way too many amps. They will be loud for a few minutes, then they will start smoking and burn up.ok so 10 times 12v equalls 120v...But im not sure about how the amps equate....

Ehhh... alright just checking cause getting 6 12v adapters for my set up isnt the easiest task, i have 6 its just half are 9v, and i wanted full power... Well i tried...
Even though these fans take .3 amps? that would be 3 amps drawn..?
how many amps does the outlet put out??

an outlet puts out as much as the breaker and wired are rated at. 15 amp. 20 amp, 30 amp, etc... as far as hooking fans directly to outlet, that will def not work. you can hook two fans to one charger, as long as the charger amps doesnt exceed the two combined fan amps. you see? some chargers have that wrote as miliamps also, which is only a thousandth of an amp,

thats right huh? well fuck that up the butt. Yeah good idea on the amp ratting or a charger. The highest Ma rating of all my fans is 850ma. So how the hell do you do the math on that one??
Thanks for the input.

I'm sorry i gave you somebad info, as long as the two fans dont exceed the charger amps. My bad there. 1000 miliamps=1 amp
does your fans have an amp rating on them?

So you've got one fan that draws 850ma? What about the others? Add them all together and that's how many amps the adapter must handle. You can run all your fans (wire them all together in parallel) off one adapter you just need to find an adapter that can generate enough amps. I know RadioShack sells a 1.5amp off the shelf. Probably whatever size you need is available one way or another.
I've been told it's not wise to wire fans together if they are not identical fans. I'm not sure why that might be though. Something to do with the hertz the motors run at or something [shrug?]. I'm also told to only use 80% of an adapter's rated amperage. Makes sense for the longevity of the adapter. I suppose an adapter run 24/7 at it's maximum amperage might burn out.

Theres the wealth of knowlege i seek. Fuck yeah, good info and plus rep+.
Ok sometimes im seriously somewhere else when im typing. I meant my fans draw .3 amps, and there all thermaltake silent cats. same fans. My highest rated adapter is 850ma. So say i get one of those 1.5 amp adapters from radio shack. I could safly run what... .3 X 5 being 1.5 amps? But you think its a bad idea to run then at max amps, so would 4 be a safe bet?

I think 4, 0.3amp fans would be just fine on a 1.5amp adapter. The adapter can have more amps than you need, no problems. It just can't have less amps and you don't really want it to be equal amps.
If you'd have to buy more than one of the 1.5 amp RadioShack adapters to run the fans you want, consider just getting a larger amperage adapter. These folks have them up to 6 amps. 12vAdapters.com: 12 Volt DC Power Supplies Adapters. 1, 2, 3, 4, 5 Amp 12V (1A, 2A, 2.5A, 3A, 3.5A, 4A, 5A, 6A) It's cheaper to buy one larger adapter than to buy two smaller ones. But whatever is easier for you.
