Mounted at a 45 degree angle in front of the extruder's 40 mm fan, this 50 mm fan provides users with greater control over the cooling rate of extruded filament material.

* Depending on when you purchased your M2, you may have a 12 volt or 24 volt 50 mm fan. If you are unsure which fan you need, you can examine the label on your current fan to verify its voltage.
