散热风扇的速度设置

散热风扇使用PWM来实现自动调速,会根据当前的CPU温度来决定风扇的开关,以及风扇的转速,如果当前的CPU温度不高,风扇会被关闭或者以较低转速旋转 (减少不必要的环境噪声),如果你想改变风扇的调速行为,请修改以下文件:

/usr/bin/start-rk3399-pwm-fan.sh

需要禁止开机自动启动风扇(比如你需要连接其他的PWM设备),请输入以下命令:

systemctl stop pwm-fan
systemctl disable pwm-fan

或者删除下面这两个文件:

/etc/systemd/system/pwm-fan.service
/etc/systemd/system/multi-user.target.wants/pwm-fan.service
