I want vortex, but can't afford them...also keep in mind that I have a room, not just cabinet, and AC so, I don't have quite the problem...
If BGH sells fantech as their premium fan, then i am sure it is every bit as good as vortex...there are a couple german fans out there too, I think.
I know you want in the area of 450-600cfm on the input and the output...
