I already used the correct pwm fan, since it came off a laptop that could change the speed of the fan. It also worked with the raspi config in the performance options. For the config .txt, how should I put

Code:

Name:   pwm-gpio-fanInfo:   Configure a GPIO connected PWM cooling fan controlled by the        software-based GPIO PWM kernel moduleLoad:   dtoverlay=pwm-gpio-fan,<param>=<val>Params: fan_gpio                BCM number of the pin driving the fan,                                default 18 (GPIO 18)        fan_temp0               CPU temperature at which fan is started with                                low speed in millicelsius,                                default 55000 (55 °C)        fan_temp1               CPU temperature at which fan is switched                                to medium speed in millicelsius,                                default 60000 (60 °C)        fan_temp2               CPU temperature at which fan is switched                                to high speed in millicelsius,                                default 67500 (67.5 °C)        fan_temp3               CPU temperature at which fan is switched                                to max speed in millicelsius,                                default 75000 (75 °C)        fan_temp0_hyst          Temperature hysteris at which fan is stopped                                in millicelsius,default 5000 (resulting                                in 50 °C)        fan_temp1_hyst          Temperature hysteris at which fan is switched                                back to low speed in millicelsius,                                default 5000 (resulting in 55 °C)        fan_temp2_hyst          Temperature hysteris at which fan is switched                                back to medium speed in millicelsius,                                default 5000 (resulting in 62.5 °C)        fan_temp3_hyst          Temperature hysteris at which fan is switched                                back to high speed in millicelsius,                                default 5000 (resulting in 70 °C)        fan_temp0_speed         Fan speed for low cooling state in range                                0 to 255, default 114 (45% PWM duty cycle)        fan_temp1_speed         Fan speed for medium cooling state in range                                0 to 255, default 152 (60% PWM duty cycle)        fan_temp2_speed         Fan speed for high cooling state in range                                0 to 255, default 204 (80% PWM duty cycle)        fan_temp3_speed         Fan speed for max cooling state in range                                0 to 255, default 255 (100% PWM duty cycle)
into the config?

The fan model is also KSB05105HC
