PiCoolFAN4
To set a new threshold (whatever you decide), we use an I
desired temperature threshold:
sudo i2cset -y 1 0x60 0x0f 0xaa && sudo i2cset -y 1 0x60 0x01
We have broken down the command below so that you can understand what each part does:
sudo i2cset -y 1 0x60 0x0f 0xaa && sudo i2cset -y 1 0x60 0x01
the new configuration
This example is setting the threshold to
for their requirements.
Remember, in this scenario based on the factory default setup, we're setting the PiCoolFAN4's
temperature sensor reading for the threshold. Should you wish to use the Raspberry Pi's internal
temperature sensor as the threshold sensor, see page 18.
