Specifications

• Fan Type: PWM fan active cooling
• Fan cable: 4Pin JST
• Weight (gross/net): 0.055/0.045kg;
• Dimension: 105 * 80 * 18 mm

NOTE

If the board is not hot, the fan will not spin. It's an actively managed cooler. If the board is cool enough, the fan doesn't spin because the board doesn't need cooling. As the temperature of the Raspberry Pi increases, the fan reacts in the following way:

• Below 50°C, the fan does not spin at all (0% speed)

• At 50°C, the fan turns on at a low speed (30% speed)

• At 60°C, the fan speed increases to a medium speed (50% speed)

• At 67.5°C, the fan speed increases to a high speed (70% speed)

• At 75°C the fan increases to full speed (100% speed)

The same mapping of temperature ranges to fan speeds applies to temperature decreases as well, with a 5°C hysteresis; fan speed decreases when the temperature drops to 5°C below each of the above thresholds.

How to config it on HAOS

To control the armor lite V5 on a Raspberry Pi 5 running Home Assistant Operating System (HAOS), you need to modify the config.txt file and potentially use a custom integration. The fan is controlled by temperature thresholds set in config.txt, which can be adjusted to customize fan behavior.

• Steps to Control the Armor lite V5 Cooler:

Access the config.txt file: Connect a monitor and keyboard to your Raspberry Pi 5. press "ctrl + F2 "

Log in to the command line as the root user with no password, Navigate to the /mnt/boot/firmware/ directory. Edit the config.txt file using a text editor vi.

vi /mnt/boot/firmware/config.txt 

adding following parameters

 
dtparam=fan_temp0=35000
dtparam=fan_temp0_hyst=5000
dtparam=fan_temp0_speed=175

• Add or modify fan settings:

Add or modify the following lines to control the fan's behavior based on temperature: dtparam=fan_temp0=35000: Sets the first temperature threshold to 35°C. dtparam=fan_temp0_hyst=5000: Sets the hysteresis to 5°C. The fan will turn off when the temperature drops 5°C below the threshold (30°C). dtparam=fan_temp0_speed=175: Sets the fan speed to 175 when the temperature reaches 35°C. You can adjust the temperature thresholds, hysteresis, and fan speeds to your desired levels. Refer to the README file in /boot/firmware/overlays/ for more available options.

• Save the changes and reboot:

Save the config.txt file and exit the text editor. Reboot your Raspberry Pi for the changes to take effect.

How to monitor fan speed on HAOS

Add this command line sensor, you must be running HassOS:

- sensor:
    name: Armor Lite V5 Fan
    unique_id: Armor_lite_v5_fan_rpm
    scan_interval: 15
    command: "cat /sys/devices/platform/cooling_fan/hwmon/hwmon1/fan1_input"
    unit_of_measurement: "RPM"
    value_template: "{{value}}"
