Looking for some advice with electric wiring - any electricians out there?

Hi all,

I just had a quick question regarding some terrarium wiring for computer fan cooling. I currently use a 4 channel fan controller that transforms to 12V DC and is rated for 3 amps. My question is, is it problematic if the sum of the fans that I hook up to this unit exceeds 3 amps? I have a myriad of 12V fans rated at 0.17-0.6amps plugged in, and I have more than 4 connected via splitters, soldered etc...and I'm quite certain the sum of the current exceeds 3 amps.

I ask because I want to buy a new controller so I don't have so many splitters, and the one I'm looking at with 8 channels is only rated at an output of 1 amp, which makes it effectively worse for my purposes.

Assuming that I am correct in my understandings of current, and it is bad that I am using this one fan controller, does anyone have suggestions on what a better power supply would be to power all my fans? I have 14-16 fans I need to power. I was contemplating an old computer supply unit, but I don't want to work with the molex plugs, and would prefer to keep everything to the 2pin/3pin connectors, which my current fans all utilize.

Thanks all!

 

EDIT - seems like I did a bit of research and got my answer!
