在 Ubuntu 14.04 上，我的风扇总是转，即使在空闲时也是如此。在 Win7 上则不是这种情况，它只在我播放电影时才转。
这让我非常困扰，我关注了与我的问题相关的其他帖子，并遵循了给出的建议。
因此，我现在将输出相关线程中建议的一些工具的结果，以便高级用户可以提供更多见解。
运行后sensors detect -u我得到了以下安装的模块：
k10temp AMD Family 10h+ CPU core temperature monitor
跑步modinfo k10temp可得：

我不明白为什么“使用者”列是零......
我曾经ftws fan -得到以下输出：
Test: Simple fan tests.

SSED: Test 1, Fan cooling_device2 of type Processor has max cooling state 3
and current cooling state 0.
PASSED: Test 1, Fan cooling_device3 of type LCD has max cooling state 7 and
current cooling state 0.
Test 2 of 2: Load system, check CPU fan status.
Test how many fans there are in the system. Check for the current status of the
fan(s).
Loading CPUs for 20 seconds to try and get fan speeds to change.
Fan cooling_device1 current state did not change from value 0 while CPUs were
busy.
Fan cooling_device2 current state did not change from value 0 while CPUs were
busy.
ADVICE: Did not detect any change in the CPU related thermal cooling device
states. It could be that the devices are returning static information back to
the driver and/or the fan speed is automatically being controlled by firmware
using System Management Mode in which case the kernel interfaces being examined
may not work anyway.

跑步sensors -u可得：

然后我跑了，pwmconfig结果告诉我：
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
所以我现在不知道该去哪里。我可以控制我的风扇吗？ 如果是，如何？
答案1
在启动高级选项中按 f2 发现有一个选项可以关闭 CPU 速度控制，禁用后问题就消失了。风扇速度保持稳定，但你最好把手放在笔记本电脑上来检查温度，因为互联网现在运行良好。
