DIY 3d printer enclosure and fume exhausting system

3D printing fumes are NOT good for you. Malcolm Langille made an enclosure for his Type A 3d printer with exhaust system to extract the fumes outside of his house.
I wonder how the temperature change and build surface cooling due to strong air movement affects the 3d print quality.
