    Description

    This is a customized cooling fan for Raspberry Pi Compute Module 4 (CM4). Compatible with both wireless and non-wireless versions.

    Due to the higher performance of Compute Module 4, its power consumption gets higher than Compute Module 3+. The temperature of the CPU is close to the temperature limit - 85°C when the environment temperature is 25°C and the CPU is fully loaded. Besides that, PMU and Wireless Module (CM4 with wireless function) are also very hot.

    Four thermal-conductive pads are included in this cooling fan and should be attached to:

    • CPU IC
    • RAM IC
    • Ethernet Controller IC
    • PMU (Power Management Unit) IC

    on the CM4 as shown:

     

     

    Before mounting the cooling fan to the CM4 module. The heat of these four components is dissipated by the metal plate at bottom of the cooling fan. Super effective.

    The cooling fan fit perfectly onto the CM4 and it allows access to the onboard antenna or the U.FL connector for external antenna:

     

    The fan is super low noise when it is running and the cooling fan is terminated with a 4-pin connector for plug and use on Raspberry Pi CM4 IO board. Compatible with the:

     

    Note: This fan requires a 12V Power Supply. Make sure your development board has a 12V power supply terminal.

     

    As it comes with a cooling fan, this is an active cooling and you can be sure it will keep your CM4 cool even overclocked :) It keeps the CPU temperature well under 35ºC at factory clock speed.

    Installing The Cooling Fan to CM4, and the IO Board:

    1. Connect the U.FL connector for an external antenna if you are using Wireless CM4 and needed the external antenna.
    2. Peel the protective sheet (One side at a time) of the thermal pads and place it properly on the dedicated IC according to the size.

    1. Mount the Screws: Two options:
      1. Option 1: Combine the Cooling fan and CM4 module into a standalone unit. This enables the CM4 to be swapped/removed from the IO board easily.

    1. Option 2: Mount the Cooling fan, CM4, and IO Board properly and firmly for robust condition.

     

    Warranty Period: 12 months
