I'm learning about electronics and have been reading the nice books on this site. Thanks to whoever wrote them.

Anyway, now it's time to get some practice in and I need a little help.

The goal:

Build circuit of (2) DC computer case fans rated at 12v (0.60A) and maybe 2 to 4 LED's.

I've already figured out what I need in terms of resistors for the LED's and how to connect them but I'm stuck on how to approach the fans. I'd like to use my wall wart which is outputting exactly 14.40Volts as measured with my multimeter. Its a 12V, 300mA supply.

I know the fans are rated to run at 12V, but will 2 of them run off the same supply or do I need to be looking at the current (mA) rating of the supply instead? That's what I'm not clear on. Both Fans would need 1.2A of current.If that's the case, my power supply @300mA wont cut it right?

In terms of voltage, again the powersupply is outputting 14, I need 12v. Does that mean that I couldn't use the same wall wart to light up (2) 12v fans or am I on the right track with the amperage calculation above?

The answers to this will really help my understanding of electronics as so far I've been toying with fans and LEDs and once I understand this a bit more I can apply this to building simple circuits.

Thanks in advance. Now where did I put that 2A wallwart
