Hi
Not sure this is correct part of the forum, if not, please move it.
As showed in picture, I want a fan to suck through a filter, but I am unsure where to place the fan in regards to the filter. In the picture I've drawn 3 options.
1.Perpendicular on filter
2.Paralell
3.Diagonal
What I am worried about is mostly adequate airflow.
Fan location in regards to filter

I think the air filter media that Bluefront posts about is the same spun-glass filter media I use.
It's quite good for noise-isolation directly in front of the fan. I think the 'pleated surface' helps a bit, by providing most of the media surface at a 45-degree plane relative to the front face of the fan. The actual media thickness is about 1/8" thickness fiberglass backed by soft wire reinforcing mesh. The actual surface area, due to the pleating, is larger than for non-pleated media.
If I'm seriously listening for it, I can still my front fan start up and also very faint seek-noise from my suspended drive, but it's really minimal.
If I knew a better solution, I'd post about it.
Hipe this helps!
