No doubt using the fan to exhaust out is the way to go ,That is similar to what I do.
After several different methods from paper bags to a dehydrator with no heat, I settled on using a small grow tent with a 4 inch inline fan exhausting out. This work great in my humid environment.
I found that blowing in dried too fast and lost some small amount of smell and flavr. Exhausting out instead seems just right!!!!
6 days in still smelling strong getting ready to put the popcorn buds in a jar, stems are snapping as we speak.
