fans-what power supply to use?

[TheMcs]

Just got 12 cooling fans, I need to know what power supply to use. They are 80mm case fans, here are the specs;
Voltage: 12V

Power: 1.6W

Rated Current: 0.13A

I'd like to use no more than 2 plug ins for the fans. Not decided on a layout, I'll use anywhere from 8-12. The fans plug into a harness that has male/female 4-prong plugs, looks like I could gang them together and run 1 plug to an adapter/plug-in. Any advice would be appreciated.

old computer power supply.

For 12 fans, rsteagall has the right idea. You can even incorporate 3 of these fan controllers to allow you to adjust the speed properly for your fans. That particular unit also comes with 4 temperature sensors too. Unfortunately, you would need 3 to control all those fans though...

Didn't even think of using a computer power supply. Would one run all 12 fans? Could I simply clip the wires from the supply that I won't use?

As long as the computer power supply will put out more than 1.56 amps on the 12 volt line, (and most will), it will work fine for all 12 fans, and yes you can cut off the extra leads. Only catch is if it is an ATX powersupply you will have to modifiy it slightly to make sure it comes on when the power is applied and you can read this to see what you need to do.

Where did you get your fans from? What RPM, CFM, dB do they give? I am trying to put together a cooling fan setup for my tank as well and am having this same problem.

Here is what I use and the selectable voltage allows you to dial in the fans so they are whisper quiet.

I did this in a past tank; these things are tanks.

Fan Controller At 8 amps of usable power you can run a ton of fans, and they are temprature controlled. Your choice voltage, current, TC or RTD.

I got mine from here for 4.95 each. i bought 6 to share with other control fanitic reefers, 5 are now gone

Just look around, i'm sure they are still available.

I got mine on ebay, just search for 80mm blue case fan, guy's name is ezshop or something similar. He gave me a discount for the # I bought.

Definitely use an old (and usually FREE) computer power supply
