4010 DC 5V Brushless Cooling Fan - 40mm x 40mm x 10mm Mini Fan with 30cm Cable

Product Description

The DC 5V 4010 Cooling Fan is a compact, high-efficiency brushless fan designed for localized heat dissipation in tight electronic assemblies. Measuring 40x40x10mm, this mini fan is an industry standard for cooling 3D printer hotends, Raspberry Pi cases, and small power supply modules. It operates on a standard 5V rail, making it directly compatible with microcontroller GPIO pins or USB power sources. The unit features a lightweight thermoplastic frame and seven aerodynamic blades, providing a balance of high-speed rotation and low acoustic noise. With its pre-installed 30cm cable and XH2.54-2P connector, it offers a plug-and-play solution for maintaining optimal operating temperatures in various DIY and industrial projects.

Key Features

• Compact Form Factor: The 10mm thin profile allows for installation in slim enclosures and crowded PCB environments.

• Low Noise Operation: Engineered with precision bearings to maintain a noise profile below 25 dBA, ideal for office or home environments.

• Brushless Motor Design: Ensures a longer operational lifespan and higher reliability compared to traditional brushed motors.

• Plug-and-Play Connector: Comes with a pre-crimped XH2.54 2-pin connector, compatible with most 3D printer controller boards and Pi headers.

• High Air-to-Size Ratio: Delivers up to 6 CFM of airflow despite its miniature size, preventing thermal throttling in sensitive components.

Technical Details

• Voltage Range: Operates reliably between 4.5V and 5.5V DC, suitable for most logic-level power rails.

• Power Efficiency: Low current draw (typically 100mA-140mA) minimizes the load on the host power supply.

• Static Pressure: Designed to push air through dense heatsinks or small ventilation grilles effectively.

• Direct Pi Compatibility: Can be powered directly from Pins 4 (5V) and 6 (GND) of a Raspberry Pi header.

• Blade Geometry: Features 7 high-angle blades optimized for high-velocity axial airflow.

• Environmental Resistance: Built to withstand standard indoor operating temperatures up to 50°C.

• Insulation Resistance: Housing material provides high electrical insulation to prevent shorting against metal chassis.

• Mounting Versatility: 35mm hole spacing fits standard M3 or M4 mounting bolts found in 3D printer kits.

• Cable Flexibility: 30cm lead length provides ample reach for routing through cable chains or internal conduits.

• Thermal Protection: Internal IC protects the windings from damage if the blades are physically obstructed.

• Start-up Voltage: Reliable starting torque even at slightly lower voltages (approx. 3.5V).

• Speed Stability: Maintains consistent RPM even during minor voltage fluctuations in the power rail.

• Lead Wire Durability: 26AWG or 28AWG stranded copper wires for repeated flexing without breakage.

• Universal Applications: Widely used in DVRs, network switches, and custom LED heatsink assemblies.

• Maintenance-Free: Sealed bearing design requires no periodic lubrication throughout its service life.
