*** WARNING *** For Meanwell Powersuplly ( Ender 3 Pro ) ONLY!! Will not work on base Ender 3 In my quest to silence my Ender 3 Pro, I developed a modification to allow for the installation of a 92mm Noctua fan. This greatly reduced the noise and reduced my printer's decibel levels by about 10db! <h1>Bill of Materials:</h1> - Noctua NF-B9 redux-1600 https://www.amazon.com/gp/product/B00KF7OMTI/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1 - 8x Coarse fan screws - https://www.amazon.com/Computer-Cooling-Mount-Screws-Pack/dp/B01LLKY3GO/ref=sr_1_1?dchild=1&keywords=fan+screws&qid=1609631713&s=electronics&sr=1-1 - 92mm Fan Grill Guard - https://www.amazon.com/Frozen-Cpu-4328449813-Black-Grill/dp/B006X1RJZY/ref=sr_1_5?dchild=1&keywords=92mm+fan+guard&qid=1609631750&s=electronics&sr=1-5 - JST Crimp Kit - https://www.amazon.com/gp/product/B07ZK5F8HP/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 - 1x XH-2Y JST - 2x XH 2.54mm pitch female pin connectors <h1>NOTES:</h1> - WARNING - Taking apart a power supply is EXTREMELY Dangerous and can cause serious injury or even DEATH. I am in no way responsible for any injury or damage caused by using this design or modifying your powersupply. Use at your own risk!!! - If you choose to proceed, drain ALL of the power from the capictors Prior to disassembly. Unplug the unit from the wall, and attempt to power on the printer. Leave the swith in the on position for at least 30s. Take care NOT to move any motors during this time as they will act as a generator and backfeed power into the supply. - Be careful to avoid touching anything inside the unit or using metal tools inside the unit. - Avoid making contact with the large capacitors in the top right at all costs. - Re-uses all stock parts / screws - Orientation - should be correct in files - Clip Yellow wire on Noctua fan. Use remaining black and red wires to create a a 2 prong JST crimp that fits the stock PSU plug. </p> <p> Made in Tinkercad, Sliced with Cura 4.8.0 </p> <p> If you enjoy my work, please consider supporting me with a tip! </p> * BTC- 18SsPKD3CzhmuRVMnEhBSs2tRLXxYwyZWH * ETH- 0x9d06F3e0A89b19c276f05778aC476AeF4790D905 * DOGE- D8e9s3L9fdjsa9k9zG2URB2EUnAAjWqnSm * Paypal- paypal.me/onienzeru Thanks!
