So my friend gave me some extra 120mm fan filters to use. They were too big so I took the filters out of the plastic grill and just put them around my two fans, and used some rubber bands to hold them in place. Probably the most 'ghetto' part about my computer.
i should probably do something like that for my middle areocool fan on my case, since my dust filter wolnt fit over the hubcap and i dont want to take the cap off lol
