FormD T1 1.1 - Ống dẫn quạt Noctua NF-F12 PWM 120mm

Remixed the O11 fan duct to fit in the FormD T1 together with my beloved Noctua NF-F12 PWM fans. It's a snug fit so that all of the air pressure is working to get the hot air out of the case instead of just circulating between the case and the fans. Had the im pression that the fans just reintake a bit of the hot air trapped in the upper case becasue the air is not really directed to the top part of the case and pushed out.

With the ducts the full air pressure is working every bit of the hot air out of the case.

I also enlarged the holes for the screws so that the normal self tapping fan screws fit through.
