Axial fans have really poor static pressure. You'd need a centrifugal blower to overcome that type of resistance with any real CFM.

Now what would happen if you had surround attached to a vacuum?

You would be pulling fresh air around the filament in all directions.

Plus you'd be sucking fumes in.

Been working with Polypropylene, extruding at different temps, heights, fan on/off, etc. 

I've been using a 64mm fan, which cools well, but it actually distorts the extruded plastic so that instead of being round, it's oval in shape.

I've been thinking about modifying this and having the extrusion pass through it on the way down.

Any thoughts?

My wife came up with something along these lines - she put a large index card bowed in front of the fan (down on the left and right, up in the middle), and punched holes down the middle, so it forced the air directly at the filament. It also serves to hold the filament straight, a nice "plus".
