Hey guys thought I would ask here if anyone has an innovate solution to this problem.

My PC is in the hallway in the house (we have an odd house) the are 3 smokers in the house and 4 dogs of which all of them have free reign while working at a farm so get nicely muddy etc.

I am trying to think of what would be the best cooling solution to use as the is an inordinate amount of dust and particles in the air (currently clogging up filters like mad). I have cm690ii case with its pre fitted filters over the front, bottom and top of the case with home-made filters over the vents on the side of the case (both). The issue is that particles still get through and if I use denser filter material (currently using stretched tights) the air flow drops too much. Also the filters clog up pretty rapidly.

Thought liquid cooling would have the same issue at the heat exchange point ?

Any novel ideas or suggestions?

Before someone says put PC in different room, I can't.
