Buck converters offer great bang for your buck. They allow you to regulate down the 12V/24V power from your 3D printer power supply to use for your Raspberry pi, cooling fans or anything else. This guide will show you how to power your Octoprint Pi in two ways, how to install a Noctua fan for the hot end and configure a larger blower part cooling fan to reduce whine.

Everything is step by step, and all of the components are cheap and versatile. The wiring job I did on my pi connector was ugly I know, the thickness of the wire was too large and the pins needed significant persuasion to enter the connector housing.

The main components of this video were requested by two of my Patrons.
