it would be interesting to have someone who understands fluid dynamics (paging @Jonathan 's brother) to critique these types of asymmetric setups.
I think what you would find if you could map this is that you’re actually reducing the effectiveness of both fans by having them compete with each other.
You might actually find you are better off relocating the left hand LASKO to the floor and positioning it similiar to the right, and have both smaller Honeywell fans (love those little guys) pointed at your face.
