我正在尝试找到解决笔记本电脑持续过热问题的方法。
我发现当 CPU 空闲时，它几乎不工作（利用率约为 1%），
但温度却高达 70*C。
我的 CPU 是 AMD Ryzen 5 3500U。
cpupower 显示以下信息：
# cpupower frequency-info
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: Cannot determine or is not supported.
hardware limits: 1.40 GHz - 2.10 GHz
available frequency steps: 2.10 GHz, 1.70 GHz, 1.40 GHz
available cpufreq governors: conservative ondemand userspace powersave performance schedutil
current policy: frequency should be within 1.40 GHz and 2.10 GHz.
The governor "schedutil" may decide which speed to use
within this range.
current CPU frequency: 1.40 GHz (asserted by call to hardware)
boost state support:
Supported: no
Active: no
Boost States: 0
Total States: 3
Pstate-P0: 2100MHz
Pstate-P1: 1700MHz
Pstate-P2: 1400MHz
所以我知道我可以切换到恒定的 1400 MHz，但这不是我的目标。
我想降低我的 CPU 频率，将其最低频率从 1.4GHz 降至 700MHz
我该怎么做？应该使用什么工具？
此外，cpupower 显示允许的最大频率为 2.1GHz，
但 CPU 规格显示其提升值为 3.7GHz。
我该如何将其设置为最大频率？
