Small square 5 V PWM cooling fan with four-pin reverse-proof connector

LORDWORLD

LORDWORLD 40mm PWM Cooling Fan for Jetson Nano 4PIN 5V

SKU CH-HDC7-EN0GT

A 40 mm PWM fan with a reverse-proof 4-pin connector provides 5 V cooling for the Jetson Nano developer kit

  • PWM speed control matches cooling to workload
  • Reverse-proof 4-pin connector prevents wrong insertion
  • Compact 40×40×20 mm profile fits Jetson Nano board
  • 5 V power draws directly from developer kit header
  • Dedicated airflow keeps edge-compute tasks stable

Dedicated 40 mm Jetson Nano Fan

This LORDWORLD cooler is built specifically for the NVIDIA Jetson Nano Developer Kit. It draws 5 V power through a keyed 4-pin connector that prevents reverse insertion. PWM control lets the board adjust fan speed automatically based on thermal load. The 40 mm square frame fits the stock mounting points without modification.

Makers targeting the stock Jetson Nano

Developers running sustained AI workloads on the standard developer kit will appreciate the drop-in fit and PWM regulation. Builders using other single-board computers, custom carrier boards or different voltage headers should look elsewhere because the voltage, connector pin-out and mounting pattern are tailored to this kit alone. The 20 mm thickness also demands enough clearance above the module.

5 V PWM 4-pin reverse-proof connector

The keyed 4-pin header supplies 5 V and carries the PWM signal for closed-loop speed control. Its reverse-proof design eliminates the risk of bent pins or backwards insertion during rapid prototyping. Verify that your carrier board exposes the matching 5 V PWM header before purchase.

Questions about this item

Does the 4-pin reverse-proof connector carry a PWM signal for speed control?

Yes, the fan uses a 4-pin reverse-proof connector that accepts a 5 V PWM signal for speed adjustment.

Will the 40 mm by 40 mm by 20 mm housing align with the Jetson Nano developer kit mounting holes?

The fan measures 40 mm × 40 mm × 20 mm and is designed specifically for the NVIDIA Jetson Nano Developer Kit mounting pattern.

How is the fan installed, and what common mistake should be avoided?

Plug the 4-pin reverse-proof connector onto the Jetson Nano fan header; the keyed design prevents reverse insertion, so do not force it.
