Using Radxa Heatsink 2513 on ROCK 5A
Install on ROCK 5A
Stick the cooling silicone on the cooling fan, and then stick it on the chip.
Connect the power cable of the cooling fan to the fan power supply port of ROCK 5A, as shown in the figure:
Stick the heat dissipation silicone on the heat dissipation fan, and then stick it on the chip. Connect the power cable of the cooling fan to the fan power supply port of ROCK 5A, as shown in the figure:
Configuration
The operating system has three modes by default：
- power_allocator: The system defaults to fanless mode or DC fan mode. Make sure that the machine can still work stably without a cooling fan;
- user_space: Manually control cooling fan mode. Users can control the speed of the cooling fan through the command terminal according to your needs;
- step_wise: automatic temperature adjustment mode. When the temperature of the CPU is below 60°C, the cooling fan is in a dormant state; And when the temperature of the CPU reaches above 60°C, the cooling fan starts to work. Note: When ROCK 5A is in shutdown or sleep state, the cooling fan does not work.
You can use the command terminal by "retsup->Hardware->Thermal governor", then use the space bar to select the mode, the specific operation is as follows:
Press "Ctrl + Alt + T" simultaneously to open a terminal, run rsetup command as below:
radxa@rock-5a:~$ rsetup
Typing the password and select Hardware to rsetup tool interface.

If you choose user_space mode, you need to manually control the cooling fan.
Find the node of the fan device pwm-fan:
cat /sys/class/thermal/cooling_device*/type
For example, the node of the pwm fan is cooling_device1:
radxa@rock-5a: cat /sys/class/thermal/cooling_device1/type
pwm-fan
Note: The following operations take cooling_device1 as an example.
Directly open the highest speed:
radxa@rock-5a:~$ sudo cp /sys/class/thermal/cooling_device1/max_state /sys/class/thermal/cooling_device1/cur_state
You can check how many speeds the cooling fan supports through the following:
radxa@rock-5a:~$ cat /sys/class/thermal/cooling_device1/max_state
4
If you want to select the third speed, follow the instructions below:
echo 3 | sudo tee /sys/class/thermal/cooling_device1/cur_state
If you want to use another speed gear, you just need to change the number. If you want to turn off the cooling fan, just select 0 for the speed gear.
echo 0 | sudo tee /sys/class/thermal/cooling_device1/cur_state
