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.

4pin fan on RAMPS board - direct?

The question is simple - I have a RAMPS 1.4 running Marlin 1.1.9 with the three MOSFETs being used (end, fan, bed), but I'd like to have a couple other Marlin-controlled fans. One of them would be a 4-pin, 6000RPM cooler I got from a dead graphics…
