I have a 120mm fan. On it said DC 12V 0.24A. I also have this power cord that came with my cordless phone. On it said Output 12VDC 200mA. I would like to know if I use this plug my the 120 mm fan, is it going to burn out the motor on the fan? Thanks...

You won't burn out the fan, you'll burn out the power supply.
.24 amps is 240 milliamps so it will be to much of a load for the supply.

Yup, that little PS would be running 20% over rating.
It would be a hot little sucker 'til it burned out. :eek:

Hey, I know what you can try! I just did an article on monitor cooling with a 120mm fan and it's on the front page.

You can also find it here.

That 12vdc fan draws slightly more than that adapter is designed to handle but it'll probably hack it. Leave it running for an hour and then feel the power supply. If it feels too warm then you should probably choose another power source.

edit- I originally had a thread here about the project. It's here.

I hope this helps you out.

Hey, donny_paycheck, that is a great article. I am
kind of surprised it didn't have the disclaimer of
"Fry at your own risk." on there.

Concerning boonmar's little PS, yes, go ahead. Try it,
but I expect it to get really hot. Even it is gets really
warm I wouldn't do it. The only mods worth keeping
are the ones you can "set and forget."

Thanks. I know, I originally intended to add one at the beginning but I forgot.
