The fan speed can be configured trough GPIOs. The GPIO settings allow to change the fan input voltage (via some resistors). After a quick look at the hwmon sysfs interface, I have failed to find the appropriate way to expose a non-pwm fan. If any, what is the dedicated sysfs entry to set speed for a non-pwm fan ? Maybe that a fake pwm interface is needed ? Thanks in advance.
