HAVE YOU CHECKED YOUR ROUTER? IS IT ON FIRE? ARE YOU SURE? CHECK IT AGAIN. ARE YOU SURE IT'S STILL NOT ON FIRE? CHECK AGAIN. Actually, just buy Dr Cool, a dedicated router cooler that solves a problem nobody has.
Evercool's completely superfluous router accessory will keep your scalding hot flameball of IP death from burning down your house and killing everyone you know and love in a terrible fire, through a single 8cm fan, and... well, it looks like just the fan. A small fan that will probably make a whiny noise.
