本本儿的cpu最近老是过热然后风扇狂转网上找咯一个软件Cpufrequtils可控制频率最终达到降温的目的。

配置说明参照https://wiki.archlinux.org/index.php/CPU\_Frequency\_Scaling_(简体中文)

1/ install

yaourt -S cpufrequtils

2/

2.1/ add to MODULES when booting

vim /etc/rc.conf

MODULES=(vboxdrv vboxnetflt fuse acpi-cpufreq)

2.2/ Temporarily add MODULES

sudo modprobe acpi-cpufreq

3/ #configuration for cpufreq control

just change

#governor=”ondemand

to

governor=”ondemand”

在未手动设置最低与最高频率时自动设置,我这里是1.2-2.1下面我会有输出。

4/ add DAEMONS

sudo vim /etc/rc.conf

DAEMONS=(hwclock syslog-ng dbus crond fam hal cpufreq als vbox-service)

5/ reboot

这样做完之后效果还是挺明显的从默认2.1降成1.20 GHz 咱们也为节能减排做出贡献了

analyzing CPU 0:

driver: acpi-cpufreq

CPUs which run at the same hardware frequency: 0 1

CPUs which need to have their frequency coordinated by software: 0

maximum transition latency: 10.0 us.

hardware limits: 1.20 GHz - 2.10 GHz

available frequency steps: 2.10 GHz, 1.60 GHz, 1.20 GHz

available cpufreq governors: ondemand, performance

current policy: frequency should be within 1.20 GHz and 2.10 GHz.

The governor "ondemand" may decide which speed to use

within this range.

current CPU frequency is 1.20 GHz.
