This is part 2 of my airflow concept for the Anycubic I3M case.
Part 1: Anycubic I3M - PSU Cover NOCTUA 60x25
Part 3: Anycubic I3M - Double MOSFET 3D-Freunde with NOCTUA 40x10
Aims + Solution
Please have a look at part 1 - there the context of the airflow concept is explained
The mainboard fan holder has been designed so that the connectors remain accessible. The fan is located centrally above the mainboard - I used a Noctua NF-A9x14PWM with the Low Noise Adapt NA-RC7. I recommend the holder version with the three feet.
Important: so that the fan can suck in better air I had turned the grundplate (the air was rustling at the bars!) - but it is better to leave the groundplate in place: 2-3 dbA quiter, no rustling ...
The 'Anycubic I3M - Vibration Damper Feet' allow additional air intake:
