The 5015 part cooling ducts use one or two model 5015 fans. These fans are radial and have a dimension of 50mm X 50mm X 15mm. The fan used to cool the heat sync of the hot-end is a 40mm X 40MM axial fan. 12v or 24v depends on the printer you have. If you have a CR-10/S then you want the 12v fans. If you have an Ender 3 then you want the 24v fans. I do not know what voltages are used by other printer models.
