sorry but that's just nonsense. Abs prints are just as strong but much cleaner and sharper with fan.

One thing you can do is make a 5mm cylinder the same height as your print. uses way less plastic than a purge wall - but has same effect.
For longer cooling times use two at opposite corners of your build plate.
