Questions tagged [fans]

For questions related to the usage of fans on 3D Printers for the cooling of electronics *not* the print

Fans used on 3D printers generally fall into three areas:

  • Hotend fan
  • Electronics (Controller, PSU) cooling fan
  • Print cooling fan

The tag should be used for the latter category, where the extruded material is cooled.

All else being equal, is there a reason to go with 5, 12 or 24 V fan?

I'm looking for fans for my upcoming printer. In each common voltage, 5, 12 and 24 V, I see fans with the same advertised rpm, cfm, static pressure and noise. So, if all else is really equal, are there any important reasons to go with one of these…
