Few years back when i lived alone, cleaning and especially vacuuming weren't my favourites. As result of this, lots of dust got inside my computercase.
As it was damn-old pc, it didn't have any casefans, it was cool enough as it was. With my new setup, I put some rangehood-filter (that thing in kitchen that get mighty hot, where someone cooks food
) in front of my fans to keep the dust out.
I have started to think that those filters might interfere with the fans too much, but still I would like to use somekind of filters to keep the dust outside my case. There is dust, even if I got
and cleaned the house thoroughly.
Any ideas, because I can't come up with any material that could act as filter with minimal airflow blocking
