Tilted Adapter for Noctua UPGRADE Fan (remix for existing screws)

thingiverse

Remix of JKSnipers' great tilted adapter. Change to original design: added spacers sized like the old fan. To reuse screws holding old fan in place. Some info collected so far: The Noctua is much quieter than expected: https://youtu.be/1zGFZx2_k2c However, cooling is less effective and adds weight. See attached graphs (ambient 30 degrees Celsius; bed not heated). Will update this project if issues printing occur (so far none have been noticed). Assembly: Taping new fan to extruder motor made mounting and cable management easier. Cabling: Connect red wires to each other and black wires to each other. Tuck away yellow/pcm cable. Ensure Y-Axis end stop is still accessible after setup. --- Update 26.6 --- Fan: Any 40mm fan should work fine. Not sure if it needs to be PWM type. Lighter fans are preferred. The Noctua NF-A4x10 FLX used in the test video is a good example. For reference, Noctua's package states that for 12V usage: rotation 4500 rpm - airflow 8.2 m3/h - acoustical noise 17.9 dB(A) - static pressure 1.78 mm H2O Experience after some printing: Still enjoying the quieter operation a lot. However, the fan used is actually overkill since it's also much quieter than the print cooling fan. A fan with more noise and throughput would be optimal for this setup.
