yea i was thinking something similar to that but... i went to measure my router and it's about 10" long and i was thinking about buying these :
Fans
Filter
then set those on little rubber feet (i can take them off my X-540 speaker bottoms cause their no use since their screwed on the ceiling now) then I'd glue them to the base of the fan (the direction the air blows to* then set them on top of my router where there is air slits to let the air through then get 2 air filters and put them on top of the fans to filter out any air that blows into the router but my problem i have right now is a way to power the fans cause their gonna be about a good 2-3 feet away from my computer tower. so is there a way to strip the wires on the fans and some how convert it to an outlet socket? or even a double A battery?
