Node 202 - Customizable cpu fan duct for Noctua NH-L9i cooler

thingiverse

This is a remix of https://www.thingiverse.com/thing:4057643 ( [original reddit post](https://www.reddit.com/r/sffpc/comments/ecl6fu/node_202_build_with_cpu_fan_duct_mod_resulting_in/) ) I remade it with OpenSCAD to allow customization, by modifying only a couple variables. It will generate a STL with dust filter side laying down for easier printing. The provided STL is made to fit my setup: Noctua NH-L9i cooler Intel i5-7500 (any socket1151 CPU, really) MSI B250I GAMING PRO AC The better airflow can reduce your CPU temperatures by 10-15°C. Right now it is printed in PLA and CPU reaches 60°C, but I don't see any warping. If your case reaches higher temps i suggest printing in PETG or ABS. ( *Small update Aug 2020: No warping at all, PLA is good enough for my temperatures* ) ***UPDATE (02/02/2020):*** According to a couple DMs I got this can fit AM4 boards with Noctua L9a-AM4 by increasing duct_height base value from 38 to 40.5. Also according to another user this will fit a Cryorig C7 cooler with the same motherboard as original maker ( ASRock B450 Fat4lity Gaming ITX/ac ), but he didn't tell me his values. Last thing I have updated the scad comments with a better description of how and where you should measure both offset values, as it wasn't really straightforward initially, I hope is clearer now. If that is not the case, original maker made a better explanation with pictures on his Reddit post.
