What the Part Cooling Fan 4020 12V Does

The Part Cooling Fan 4020 12V is a compact cooling fan used to improve 3D print quality by directing airflow at freshly extruded filament. Faster layer solidification helps reduce stringing and supports more accurate printed results.

This 12V fan is also suitable for electronics cooling where efficient heat dissipation is needed in a small form factor.

Key Features of the 4020 12V Cooling Fan

• Efficient cooling performance: Delivers targeted airflow to rapidly cool extruded filament, helping reduce stringing and improve print accuracy.
• Compact 4020 format: The 40 x 40 x 20 mm size makes the fan easier to integrate into a range of 3D printer models without occupying excessive space.
• Low noise operation: Designed to run quietly to minimise additional noise during printing.
• Multiple bearing options: Available with sleeve bearings rated for approximately 30,000 hours, hydraulic bearings rated for around 35,000 hours, and dual ball bearings rated for up to 50,000 hours.

Where the Part Cooling Fan 4020 12V Is Used

3D printer part cooling

This fan is commonly used in 3D printers to cool printed parts during extrusion. The airflow helps stabilise layers as they are deposited, which is useful for improving detail and overall print consistency.

Electronics cooling

The compact fan can also be used in electronics applications that require efficient component cooling. Its small size makes it suitable for installations where space is limited but active airflow is still needed.

Why the 4020 Size Matters

A 40 x 40 x 20 mm cooling fan fits many compact mounting positions found in desktop 3D printers and enclosed electronic assemblies. The combination of small dimensions and targeted airflow makes the fan practical for builds where cooling performance must be balanced with limited space.
