Yes you can pull air through a carbon filter too fast and reduce the ability of the carbon to absorb the odor causing molocules. Learned that by experimentation. There may be a source that can give you exact stats on this or even someone here that knows that information, not me.
I figured what fan speed to use by gradually slowing the fan down until I no longer had and odor problem. In the case of the carbon filter I use it is a bit over half on the rheostat dial. See the link in my signature about carbon filter.
Good luck.
