You are not alone in not getting on with the airflow on a gen 3. I found it very noisy. 6 foot 4 .
I went with a Madstad bracket and then went through my pile of old screens till I found one that worked.That is the advantage of the Madstad, 5 mins with a 6mm drill bit and pretty much anything will fit, then the angle and height can be tailored to suit.
Even then I had to fit some Nylon bushes ,as per Micks post, to get that last bit right.
