Noctua Part Cooling Fan

  • Everything I read about adding a more quiet parts cooling fan comes back to using the Noctua fan 40x10. But there are two problems with that fan:

    1. It has three wires vs two wires, so how does one make the connection?

    2. Noctua fans are 12vdc so one needs to add a Buck converter but nowhere have I found which one?

    So my question is: is there anyone who sells a Noctua fan with a Buck converter and ready to connect to the two fan wires of the Ender 3/Pro ?
