WVS FANDC005040-20-PWM 5V 40mm 4-Wire Jetson Nano Cooling Fan

The WVS FANDC005040-20-PWM is a compact 5V DC cooling fan designed to provide active airflow for electronic equipment, embedded systems and development boards. With its 40 × 40 × 20mm form factor, the fan is suitable for space-constrained installations where efficient cooling is required without adding significant bulk.

The fan features a four-wire connection with PWM speed control, allowing compatible host systems to adjust the fan speed according to temperature or workload requirements. Its pulse-width modulation capability makes it particularly suitable for applications such as the NVIDIA Jetson Nano, where controlled cooling can help maintain stable operating temperatures during intensive processing.

Operating at up to 7500 RPM and drawing approximately 0.27A, this fan provides high-speed airflow in a small package. The reverse-proof four-pin connector simplifies installation and helps reduce the risk of incorrect connection.

PWM Speed Control

The four-wire design provides PWM-based speed adjustment when connected to a compatible controller or host board. This allows the fan to operate at a suitable speed for the system's cooling requirements rather than running continuously at full speed.

PWM control may help reduce unnecessary noise and power consumption during lighter workloads, while allowing increased airflow when the processor or equipment requires additional cooling. Actual control functionality depends on the connected host system and its software configuration.

Jetson Nano Cooling Application

This fan can be used as a dedicated cooling solution for the NVIDIA Jetson Nano. Active airflow can assist with removing heat from the development board and its processor during demanding workloads such as artificial intelligence processing, robotics, computer vision and machine learning tasks.

Before installation, confirm that the fan's voltage, connector orientation, mounting arrangement and PWM control requirements are compatible with the intended Jetson Nano setup.

Applications

The WVS FANDC005040-20-PWM is suitable for:

• NVIDIA Jetson Nano cooling.
• Raspberry Pi and embedded development projects where compatible.
• Processor and chipset cooling.
• Industrial control electronics.
• Networking and communication equipment.
• Small enclosures and compact electronic systems.
• Robotics and AI development platforms.
• Computer vision and machine learning projects.
• DIY electronics and prototype cooling systems.
• Replacement or supplementary equipment cooling.

Installation and Use

• Confirm that the host system provides a compatible 5V DC fan connection.
• Connect the four-pin connector in the correct orientation.
• Ensure that the fan blades can rotate freely without obstruction.
• Keep cables clear of the rotating fan blades.
• Use PWM control only with a compatible host controller or motherboard.
• Provide adequate ventilation around the fan inlet and outlet for effective airflow.

Important Information

• The fan is rated for 5V DC operation; do not connect it directly to a higher voltage supply.
• PWM speed adjustment requires compatible hardware and software support from the host system.
• The stated 7500 RPM speed and 0.27A current are specified operating values and may vary with operating conditions.
• Confirm connector pinout and mounting compatibility before installation.
• The product is supplied as a cooling fan; any additional mounting hardware or adapters should be confirmed separately.
