3dXtreme has reviewed a 80mm Aluminum Fan Filter :
The product I'm talking about are 80mm Aluminum Fan Filters. They are perfect for an intake fan or a intake blowhole, anywhere there is air coming into the case that can be filtered to avoid dust buildup inside your pc. My previous case was a Lian Li pc75 and with that case filters were already built into the front intake fans. However as luck would have it, I've built a second pc and the need for a filter prompted an Aluminum Fan Filter review. The Aluminum Fan Filters come in black or silver and are available in different sizes, check out Jab-Tech for more size options. The Aluminum Fan Filters reviewed today are for a standard 80mm case fan.
