coolgpus介绍

coolgpus为github上一个项目，python编写，可以配置NVIDIA显卡风扇转速。

项目地址https://github.com/andyljones/coolgpus

还可以pip方式安装

pip install coolgpus

该代码可以直接指定风扇转速区间

sudo $(which coolgpus) --speed 99 99

默认值运行

sudo $(which coolgpus)

也可以指定风扇转速与温度关联的曲线，例如使风扇速度从17C=15% 转速线性增长到 84C=99%转速

sudo $(which coolgpus) --temp 17 84 --speed 15 99

更可以列出任何温度和速度（增加）序列，它们将被线性插值，例如20% 30% 99%转速分别对应20C55C80C。

sudo $(which coolgpus) --temp 20 55 80 --speed 5 30 99

也可以直接创建service文件，以服务模式运行，参考以下模板

[Unit]
Description=Headless GPU Fan Control
After=syslog.target

[Service]
ExecStart=/home/ajones/conda/bin/coolgpus --kill
Restart=on-failure
RestartSec=5s
ExecStop=/bin/kill -2 $MAINPID
KillMode=none

[Install]
WantedBy=multi-user.target

其中ExecStart为启动时默认参数，可以根据实际情况修改，且要配置实际的可执行文件所在的路径，例如配置为20度50度70度分别对应20%50%99%转速。可用如下参数配置，且可以加上--kill选项，杀死任何现有的Xserver进程，以避免进程冲突，启动失败。

ExecStart=/usr/local/bin/coolgpus --kill --temp 20 50 70 --speed 20 50 99

而后可以启动服务（启动服务前应关闭图形化服务）

ubuntu16版本关闭图形化

systemctl stop lightdm.service

ubuntu18版本关闭图形化

init 3

而后启动coolgpus服务

systemctl start coolgpus.service

若要实现开机启动

systemctl enable coolgpus.service

详细使用可参考coolgpus --help 如下

usage: coolgpus [-h] [--temp TEMP [TEMP ...]] [--speed SPEED [SPEED ...]]
[--hyst [HYST]] [--kill] [--verbose] [--debug]

GPU fan control for Linux. By default, this uses a clamped linear fan curve,
going from 30% below 55C to 99% above 80C. There s also a small hysteresis
gap, because _changes_ in fan noise are a lot more distracting than steady fan
noise. I can't claim it's optimal, but it Works For My Machine (TM). Full load
is about 75C and 80%.

optional arguments:
-h, --help show this help message and exit
--temp TEMP [TEMP ...]
The temperature ranges where the fan speed will
increase linearly
--speed SPEED [SPEED ...]
The fan speed ranges
--hyst [HYST] The hysteresis gap. Large gaps will reduce how often
the fan speed is changed, but might mean the fan runs
faster than necessary
--kill Whether to kill existing Xorg sessions
--verbose Whether to print extra debugging information
--debug Whether to only start the Xorg subprocesses, and not
actually alter the fan speed. This can be useful for
debugging.
