Hi everyone!
It's been a while since I uploaded something, and in that time I gathered a few more 3D printers for my projects. The only problem was that they were all annoyingly loud. So to keep my sanity I made this video in which I silence two of them - Creality Ender 3 and Anycubic Chiron.

After the modifications from the video they're noise level went from around 40dB to 15dB which is a major improvement. They can still be heard but it's just a very delicate fan humm. The motors are dead silent and as I said in the video I sometimes forget they are even on. If you want to make your printer even quieter I would recommend getting higher quality fans like noctua, adding some foam under the printer or making an enclosure to absorb the rest of the noise. It's also a good idea to limit max speed and acceleration with Gcode to avoid any sudden axis noises.

Important disclaimer
I am not responsible for any damage that you may do to your printers. In this video I work on open power supplies which can be dangerous to both you and the hardware so make sure you unplug everything before proceeding. Also power supplies have fans for a reason and you gotta keep in mind that changing it for a quieter (usually less powerful) fan may cause the PSU to get hotter and potentially create a fire hazard. My power supplies work perfectly fine after modifications but if you use a lot of power/your printer works in an enclosure/your power supply already runs hot you should think twice about changing the fan. Keep in mind that buck converters or as in my case voltage regulators(especially they) create heat as well. Also as said in the video each printer and motherboard have different connections and capabilities so just make sure you know what you are doing.

Now with that out of the way here are the parts I used:

-TMC2209 drivers
-SilentiumPC Zephyr Fans 40/50/60
