Just update I stopped using this for cooling during prints. I find its useful for cooling the bed when the print finishes though. I print abs on glass with hairspray. The fan cools it quick and everything just pops off.
The mount for the big fan was made in preparation for a switch from printing abs to printing pla. I read somewhere that having a fan directed over the bed to help cool the overall part would be helpful with pla. It was never meant to cool the cold end of the extruder, just to create airflow over the entire bed and maybe assist the fan I was already using to cool the filament at the nozzle.
But since then I only tried pla for a day or so and I prefer working with abs so I never spent much time using it. Right now if I feel like my layer times are short and it could use a bit of extra cooling I leave it on. I don't have enough experience to show how much you can gain by adding this.
