Jetson Nano Developer Board has a fairly large heatsink but when running a CPU/GPU intensive load, it can reach the thermal limit easily. Therefore, an active cooling solution is necessary. There is an on-board fan header (J15) which can be used for this purpose.
This is an active cooling fan which can be used specifically for Jetson Nano. This fan comes with a 4-pin lead which allows you to control the activation and speed of the fan via software. This is great because the fan can be set to spin only when necessary and not running all the time.
This product comes with 4 pieces of self-tapping screws that can be used to fasten the fan to the mounting points on the heatsink.
Software control:
To turn the fan on manually at full speed, run this command:
$ sudo sh -c 'echo 255 > /sys/devices/pwm-fan/target_pwm'
Change the value 255 to other value from 0 (off) to 255 (full speed) to adjust the fan speed
