Dust filter for bottom mounted PSU

[fantazio]

Hi everyone,

I recently built a computer (it's been a while) and am worried about incoming dust. The case is Tempest 210, and the PSU is OCZ ModXStream -- I mounted the PSU on the bottom with the intake facing the ground. There is very little room between the PSU intake fan and the case, so I can't get one of those Silverstone filter things due to their thickness. I need something really thin to fit in there, but also not to impede incoming airflow by too much. Does anyone have any suggestions on what I might do?

Thanks

Any kind of filter material will do. Old HEPA filters work. Mosquito nets are another popular choice. I think you can spray a little bit of light oil on it to help trap dust, like the stuff they use on car filters.

The other option is to use one of those Silverstone filters, but drill holes on the case and mount it from the underside. This way you don't have to worry about fitting it inbetween the PSU and case.

Thanks for the reply. I don't think HEPA filter would fit. The PSU snaps into the bottom of the case, and there's very little space left to slide in a dust filter. I like the mosquito net approach! I searched Hardforum and couldn't find any posts about it. Is there a specific kind? Would this work? Link to Amazon

That kind of netting might be too light and might get sucked into the fan but it should work. It would depend on the shape of your psu fan grill. I'd look around the house to find any kind of heavier mesh first. Im thinking more of screen door material.

I use Silverstone magnetic mounting filters on bottom of my case. Tie a piece of ribbon or braid some string onto one of the screw mount holes so you can pull it off for cleaning without turning case on it's side. DEMCiflex also make magnetic mounting filters.

For something even "better" than mosquito netting and much more easily obtained and/or less expensive, nylon pantyhose works great .

Using common twist ties and attaching it to the outside of a fan grill (if you have one), it will last for years. Provides great dust filtering and is easily vacuumed as well.

The potential disadvantages: you do need a metal or plastic grill of some type between it and your fan or the hose will get sucked into it. Due to its elasticity, need to be a bit careful vacuuming. And removing and putting back on to twist-tie holders is a hassle (best just to leave it attached and vacuum directly).
