如何在苹果Mini上控制风扇？

Question

我运行12.04 LTS的苹果迷你硬件(约4岁)。

扇子似乎不停地运转着。"ThinkFan“是安装的，但我不知道如何使用它来调节风扇的速度。该软件表示，它可以通过sysfs hwmon接口与ThinkPads以外的系统一起使用。我不知道那是什么。

Answer 1

尝试使用fancontrol。也许能帮上忙。

然后可以编辑配置文件/etc/fancontrol或运行pwmconfig (sudo su - -c /usr/sbin/pwmconfig)。您也可以像这样编辑配置文件，但请记住，您有不同的硬件：

取自https://wiki.archlinux.org/index.php/Fan_speed_control

INTERVAL=10
DEVPATH=hwmon0=devices/platform/coretemp.0 hwmon2=devices/platform/w83627ehf.656
DEVNAME=hwmon0=coretemp hwmon2=w83627dhg
FCTEMPS=hwmon0/device/pwm1=hwmon0/device/temp1_input
FCFANS= hwmon0/device/pwm1=hwmon0/device/fan1_input
MINTEMP=hwmon0/device/pwm1=20
MAXTEMP=hwmon0/device/pwm1=55
MINSTART=hwmon0/device/pwm1=150
MINSTOP=hwmon0/device/pwm1=105


INTERVAL: how often the daemon should poll CPU temps and adjust fan speeds. INTERVAL is in seconds.

配置文件的其余部分被拆分为(至少)每个配置选项的两个值。每个配置选项首先指向一个PWM设备，该设备被写入以设置风扇速度。第二个“字段”是要设置的实际值。这允许监视和控制多个风扇和温度。

FCTEMPS: The temperature input device to read for CPU temperature. The above example corresponds to /sys/class/hwmon/hwmon0/device/temp1_input.
FCFANS: The current fan speed, which can be read (like the temperature) in /sys/class/hwmon/hwmon0/device/fan1_input
MINTEMP: The temperature (°C) at which to SHUT OFF the CPU fan. Efficient CPUs often will not need a fan while idling. Be sure to set this to a temperature that you know is safe. Setting this to 0 is not recommended and may ruin your hardware!
MAXTEMP: The temperature (°C) at which to spin the fan at its MAXIMUM speed. This should be probably be set to perhaps 10 or 20 degrees (°C) below your CPU's critical/shutdown temperature. Setting it closer to MINTEMP will result in higher fan speeds overall.
MINSTOP: The PWM value at which your fan stops spinning. Each fan is a little different. Power tweakers can echo different values (between 0 and 255) to /sys/class/hwmon/hwmon0/device/pwm1 and then watch the CPU fan. When the CPU fan stops, use this value.
MINSTART: The PWM value at which your fan starts to spin again. This is often a higher value than MINSTOP as more voltage is required to overcome inertia.

还有两个设置扇控制需要验证配置文件仍然是最新的。行以设置名称和相等号开始，后面是hwmon-class-device= start组，由空格分隔。您需要为配置中的任何地方使用的每个hwmon类设备指定每个设置，否则扇控制将无法工作。

DEVPATH: Sets the physical device. You can determine this by executing the command

这些值应该相应地设置为命令sensors的值。
