Noctua Fans for Carbon Filter?

So just wondering who is using Noctua Fans for their DIY filter. I ordered a few of them to try it out. Not sure if they will push enough air but will see. Would it be okay to stack two fans on top of the other?

Also I bough three of them. 2 for exaust if I need it and 1 for intake. What is the best way to power them? I've read 12v adapter but I am not good with electonics. Can I power all 3 with one adapter?

I would check out brands like EPM Papst or Delta.....Papst are the best for high millibar pressure fans, which is what you need. Noctua's and most other PC fan's have low back pressure but high air movement. Good combo for a pc case, not for a pushing air through a filter.Don't get me wrong, my next DIY LED fixture builds, will consist of Noctua's almost certainly. They are that good, but only for their DEFINED application. Air mover and not air pusher :peace:

Stacking fan's will cause them to interfere and decrease efficiency.....

You can wire in parallel, to use one 12v adaptor, but you must have at least the rated amperage of the all the fans added together in your power supply. So if 3 fans, each call for .15 amps, you would need a 12v adaptor with at least 450mA of current. More is fine, they will only draw what they need.

You can use 5v, 7v, 9v, 12v. Those are the most common. I would not recommend a 15v, because it will most likely blow the fan, although a 24v can be wired in series, if you must.

Thanks. I'm having a real problem finding a solution for a quiet carbon filter/fan so was hoping the Noctuas would cut it.
