我在 MacBook Pro（2013）上运行 ubuntu，即使启用了 mbpfan，与 MACOS 相比，它还是过热了。还有其他方法可以进一步降低运行温度吗？我看到 2010 年有一种方法可以手动设置风扇规则https://bbs.archlinux.org/viewtopic.php?id=71187
我有一台配备 Intel/Nvidia 显卡的 Mac book pro，并且我启用了 Nvidia 显卡 Nvidia GPU 使用情况
我已经安装了mbpfan采用以下温度配置：
[general]
# see https://ineed.coffee/3838/a-beginners-tutorial-for-mbpfan-under-ubuntu for the values
#
# mbpfan will load the max / min speed of from the files produced by the applesmc driver. If these files are not found it will set all fans to the default of min_speed = 2000 and max_speed = 6200
# by setting the values for the speeds in this config it will override whatever it finds in:
# /sys/devices/platform/applesmc.768/fan*_min
# /sys/devices/platform/applesmc.768/fan*_max
# or the defaults.
#
# multiple fans can be configured by using the config key of min_fan*_speed and max_fan*_speed
# the number used will correlate to the file number of the fan in the applesmc driver that are used to control the fan speed.
#
#min_fan1_speed = 2000 # put the *lowest* value of "cat /sys/devices/platform/applesmc.768/fan*_min"
#max_fan1_speed = 6200 # put the *highest* value of "cat /sys/devices/platform/applesmc.768/fan*_max"
#low_temp = 63 # try ranges 55-63, default is 63
low_temp = 55 # try ranges 55-63, default is 63
#high_temp = 66 # try ranges 58-66, default is 66
high_temp = 58 # try ranges 58-66, default is 66
max_temp = 86 # take highest number returned by "cat /sys/devices/platform/coretemp.*/hwmon/hwmon*/temp*_max", divide by 1000
polling_interval = 1 # default is 1 seconds
虽然我的 Macbook 温度仍然很高，但有人知道如何进一步控制 macbook-ubuntu 上的过热问题吗？

我使用节流/不节流脚本修复了过热问题:-)
- 安装mbpfan：https://github.com/linux-on-mac/mbpfan
- 安装CPU 功率：https://manpages.debian.org/buster/linux-cpupower/cpupower.1.en.html
- 使用 Sepero 定制的节流/取消节流脚本：http://seperohacker.blogspot.com/2012/10/linux-keep-your-cpu-cool-with-frequency.html https://github.com/Sepero/temp-throttle 我利用以下方法定制了 Sepero 的脚本CPU 功率：

[ $TEMP_FILE == "null" ] && err_exit "The location for temperature reading was not found."
### END Initialize Global variables.

throttle

sleep 3 # The amount of time between checking temperatures.
done
然后最终使用设置温度 50 的脚本后，我能够将 CPU 温度降低 10C！
