Black rectangular dual-fan module with RGB lighting and expansion board for Raspberry Pi

CAFELE

CAFELE Dual Cooler 15 Modes Expansion Board Case Fan

SKU CH-AB2K-DRDKG

Dual-fan cooler with 15 RGB modes, five speed levels and 29 dBA noise for Raspberry Pi 3 and 4 boards

  • TypeCase Fan
  • 15 RGB lighting modes adjustable via K1 button
  • Dual fan design with 5 speed settings up to 10500 RPM
  • Adjustable RGB brightness across three levels
  • Compatible with Raspberry Pi 3A+, 3B, 3B+, 4B boards
  • Low 29 dBA noise at 4.3 CFM airflow

Raspberry Pi Dual Cooler

The CAFELE expansion board fits Raspberry Pi 3A+, 3B, 3B+ and 4B models. It adds a dual-fan module with 15 RGB lighting modes and five fan-speed settings. The unit draws 0.15 A at 5 V and is controlled by two onboard buttons.

Sustained Cooling Behaviour

At full speed the fans spin at 10500 RPM and move 4.3 CFM of air while producing 29 DBA of noise. The 0.75 W power draw stays constant, so the board can run continuously without overloading the Pi’s 5 V rail.

Setup Checks

Verify that your Raspberry Pi model is listed above and that the GPIO header is free for the expansion board. Ensure the case has enough clearance for the dual-fan height and that the 5 V supply can deliver the extra 0.15 A.

Questions about this item

How loud is the dual fan running continuously at full speed?

The module produces 29 dBA at 10500 RPM while drawing 0.75 W from a 5 V supply.

What power source and connector does the board need to operate?

It requires a DC 5 V source capable of 0.15 A and connects directly to the Raspberry Pi GPIO header.

Will the cooler fit a Raspberry Pi 4B without blocking the GPIO pins I still use?

The unit is designed for full-series Pi 3A+, 3B, 3B+ and 4B boards and mounts over the GPIO header.
