Is there a good way to replace top dust filter on Corsair Obsidian 450d?


Jul 25, 2005
Merry Christmas all! The dust filter on top of my 450d case has a hole about 1 inch in diameter. I checked ebay and but could not find replacement filters there. Is there some smart way to replace the dust filter? Maybe find a different case dust filter with dimensions that are close? I think the dimensions are 386 mm x 159 mm.

Or maybe buy some mesh and cut on your own to those dimensions?

Demcifilters are great in that you can get custom sizes however the last pair I bought the magnets were week fine for vertical placement but not hanging horizontally. I use them on a 1080 extreme external loop setup though so, smaller sizes should be better in terms of hanging their own weight.
BUT most folks that have top case mounted fans use them in exhaust to take heat out of the case where NO dust filter is better. In other words only fans set as intake need a filter. Using a filter on outtake is counter productive and only diminishes cfm.
Get rid of the filter all together if top fans are set to exhaust.
