What lord said. Computers usually run on more than 12v. Even if you have and old nintendo system or playstation a power cord from there might work. I know gamecube transformers run 12V and have enough amperage to run copious amounts of fans.
Yeah, after going deeper into the topic this popped up and makes sense 100%. I never knew that the outside layer was a prefilter until then either so now it all makes perfect sense to me.
I dunno lol. It kinda makes sense tho..if you're pulling air through, its going to pull air through the filter closer to the fan...it wont be as evenly distributed. If you push it through there is always positive pressure throughout the whole filter.
Take an old cell phone adapter or any kind of AC to DC converter and match up the positive and negative. White or red is usually positive and black is negative. Most computer fans operate at 12 volts. Make sure on your AC/DC converter the output is no more than 12V or it can burn the motor...
