Objective: Louder computer; Idea: Stacking fans!

I would like to get my computer a little more louder, so I was wondering after reading this if I could stack my fans:
In order for two fans connected together to actually help each other one needs to spin one way, and the other needs to spin in the opposite way. Now you could do this, but theres a catch. The one fan (bottom) needs to have the "fins", or fan blades, tilted in the other direction then they are.

I was thinking about mounting one fan backwards against another fan and then swapping the positive and negative cables.

Would this work?

Thanks guys,

get a box fan and install it directly to your side panel. Or, better yet, MAKE it your side panel!

Seriously, even a single 92mm Sunon fan will make your machine sound like a server room. There's no need to get exotic. Having two fans working in opposite directions would either create a vaccuum between them (read: no airflow whatsoever) or a high pressure area between them (read: no airflow whatsoever.)

Another possibility is recording a leafblower and playing that sound file on autorepeat.

this. make sure to plug directly to power supply, as fan will overdraw from motherboard fan header.

Actually one of my friends burned out his motherboard from plugging in one of the huge ones (120mm x 38mm) Delta fans into his mobo haha.

Okay so the best idea is to put one fast ass fan on it? any recommendations in a 120mm size?

I remember somebody reporting that they had a fan (I think it was that one, but I'm not 100%) that was capable of hovering slightly off of their desk when powered in a horizontal position.

Ive got an 80mm fan that can literally take off doing that...some crazy turbine fan that puts out over 300cfm. Super RPMs, blades directly attached to the sides (you get more airflow the closer the blade gets to the duct), and the fact that theres no motor in the middle so quite a bit more fin area. I dont know what it is or where I got it, I cant even find pics on google. I use it to cool a CPU.

You have GOT to post pictures, that sounds AWESOME! :D

Considering that there are contrarotating fans, the idea is not completely far-fetched. But you have to test it.

One of the Arctic Cooling fans rotates clockwise. When I put it up against a normal counter-clockwise fan, the output cut way down.

Then I got one of these. It's an ugly-sounding fan which I do not recommend, but slapping it up against another fan - especially with a shroud between them - increased the output.

YMMV.

Thanks, but at $25 I could get a prepackaged Delta fan that is proven to work and has > 200 CFM
