Two 30x30x10mm 24V fans with 2-pin 2.54mm connectors and 305mm cables for 3D printer extruder cooling

  • Cools 3D printer extruders with 24 V DC operation
  • Compact 30 x 30 x 10 mm size fits tight hotend mounts
  • Standard 2-pin 2.54 mm pitch plug simplifies wiring
  • Two fans included for dual-extruder or spare-part readiness
  • 305 mm cable length allows flexible routing inside printer frames

Compact 24 V cooling fans for 3D printers

Two 30 x 30 x 10 mm fans run on 24 V DC and connect with a 2-pin 2.54 mm pitch plug. Each unit includes a 305 mm cable and mounting holes spaced at 24 x 24 mm with a 3.5 mm diameter. They are designed to exhaust heat from hotend heatsinks on RepRap, Rostock, Prusa Mendel and Huxley machines.

Suited for direct hotend cooling upgrades

Builders replacing a worn extruder fan or assembling a new 24 V hotend will find the form factor and voltage match common open-source designs. Users running 12 V electronics or needing a 4-pin PWM connector for motherboard control should look elsewhere.

24 V DC rated voltage decides compatibility

The fan only operates correctly from a 24 V supply; connecting it to a lower voltage will not spin the rotor and connecting it to a higher voltage risks damage. Verify your printer’s hotend voltage before purchasing.

Questions about this item

How many millimetres of clearance does the 10mm frame need above the heatsink?

The fan body is 10mm thick, so allow at least that much space above the heatsink surface.

Does the 24V 2-pin connector draw enough current to need a dedicated fan header on the printer board?

The unit uses a standard 2-pin 2.54mm pitch plug that connects directly to a 24V fan header.

Which mounting-hole pattern must the heatsink or bracket already have for these fans?

Two holes of 3.5mm diameter spaced 24mm apart in a square pattern.
