Everything fits great, i just wanted to get this out there for everybody. ill update with more details later.
almost forgot you will have to remove a small foam peg that's on the circuit board otherwise it will interfere with the fan blade's
I used a 40mm 5v fan. (Noctua brand is super quiet)
It works reasonably well I can feel a slight draft coming in around the nose area and pushed out through the front of the headset, I think a dual fan set up might be too much and dry out your eyes.
