節能 降溫 把灌LINUX OS的 CPU降頻

一樣是熱死人不償命的天氣
如何把CPU降溫 只能手動降速 讓他減少功率的消耗

[root]# cpupower -c 0,1 frequency-info
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: 1000 MHz - 1.67 GHz
available frequency steps: 1.67 GHz, 1.33 GHz, 1000 MHz
available cpufreq governors: ondemand, userspace, performance
current policy: frequency should be within 1.30 GHz and 1.67 GHz.
The governor "userspace" may decide which speed to use
within this range.
current CPU frequency is 1.33 GHz (asserted by call to hardware).
boost state support:
Supported: yes
Active: yes
analyzing CPU 1:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0 1
CPUs which need to have their frequency coordinated by software: 1
maximum transition latency: 10.0 us.
hardware limits: 1000 MHz - 1.67 GHz
available frequency steps: 1.67 GHz, 1.33 GHz, 1000 MHz
available cpufreq governors: ondemand, userspace, performance
current policy: frequency should be within 1.30 GHz and 1.67 GHz.

within this range.
current CPU frequency is 1.33 GHz (asserted by call to hardware).
boost state support:
Supported: yes
Active: yes

由上可以得知 我的1.6G的CPU設定跑1.33G的狀態
最少最少還可以降到1.0G穩定運做看看

[root]# cpupower -c 0,1 frequency-set -d 1.0G -u 1.67G
Setting cpu: 0
Setting cpu: 1

設定以後 就會看到CPU被降頻到1.0G的速度了

至於溫度有沒有降下來 看起來不明顯@@
先觀察看看
