Reversing top exhaust for radiator intake, dust filters?

[ZeroOne]

What's best to use for low restriction, dust prevention on a radiator? A sheet of material would be fine, cut to fit, and sandwich between case and radiator.

Reversing the top fans to pull-intake, for top mounted radiator in a Vengeance C70. The bottom has a nice intake filter stock, but nothing up top, as it was designed for exhaust.

Right now, cool air comes in the bottom radiator, enters the case, blends with other intaking air, and half exhausts through the top mounted radiator (putting heat back in the loop). Added a video card to the loop and wanted more cooling for low volted fans...

Just blow it out with a compressor and a blower attachment every other month or so.

Unless the filters are easily removable they wont offer you any convenience and probably be more of a PITA

Here is a link to a good electric blower to use instead of canned air. Newegg has them too. This is what I use. It's noisy - like a vacuum cleaner - but works great with no empty canned air to dispose of.

Thanks for the ideas and links! Have a 20lb co2 tank but always seem to run out. Didn't realize they made electric blowers for dusting! Will have to check those out.
