我试图降低 CPU 风扇的噪音，起初 pwmconfig 没有显示任何内容，按照一个小指南操作后，它起作用了，但我仍然不知道如何降低 RPM。现在我注意到传感器显示以下内容：
it8728-isa-0a30
Adapter: ISA adapter
in0: +2.22 V (min = +0.84 V, max = +2.32 V)
in1: +2.22 V (min = +2.71 V, max = +0.48 V) ALARM
in2: +2.02 V (min = +0.65 V, max = +2.52 V)
+3.3V: +3.36 V (min = +6.00 V, max = +4.13 V) ALARM
in4: +3.06 V (min = +2.74 V, max = +0.95 V) ALARM
in5: +3.06 V (min = +2.29 V, max = +2.24 V) ALARM
in6: +2.22 V (min = +2.50 V, max = +1.45 V) ALARM
3VSB: +3.29 V (min = +0.17 V, max = +2.16 V) ALARM
Vbat: +3.22 V
fan1: 2647 RPM (min = 631 RPM)
fan2: 0 RPM (min = 85 RPM) ALARM
fan3: 0 RPM (min = 28 RPM) ALARM
temp1: -68.0°C (low = +22.0°C, high = +5.0°C) sensor = thermal diode
temp2: +23.0°C (low = -87.0°C, high = -73.0°C) ALARM sensor = thermal diode
temp3: -77.0°C (low = -11.0°C, high = +37.0°C) sensor = Intel PECI
intrusion0: ALARM
我担心的是-68°C和-77°C
我是不是弄乱了某些配置？我该如何修复？在 Windows 中，风扇一直都安静得多。我在网上搜索，但只找到了如何通过运行传感器检测来修复传感器的方法，我已经这样做了。
抱歉我的英语不好，希望你能帮助我:)
答案1
所以我在实时 USB 上传感器的结果
acpitz-virtual-0
Adapter: Virtual device
temp1: +27.8°C (crit = +106.0°C)
temp2: +29.8°C (crit = +106.0°C)
nouveau-pci-0100
Adapter: PCI adapter
temp1: +36.0°C (high = +95.0°C, hyst = +3.0°C)
(crit = +105.0°C, hyst = +5.0°C)
(emerg = +135.0°C, hyst = +5.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +35.0°C (high = +85.0°C, crit = +105.0°C)
Core 0: +26.0°C (high = +85.0°C, crit = +105.0°C)
Core 1: +31.0°C (high = +85.0°C, crit = +105.0°C)
Core 2: +35.0°C (high = +85.0°C, crit = +105.0°C)
Core 3: +34.0°C (high = +85.0°C, crit = +105.0°C)
它只是消失了..我会尝试传感器检测..
我没有让传感器显示更多内容，我安装了 fancontrol 并多次运行传感器检测。pwmconfig 显示“没有安装支持风扇的传感器模块”
我猜那是因为我的系统没有更新/升级，因为它是一个生命系统（抱歉没有撇号等。每个特殊字母都很痛苦，因为我的生命系统上没有正确的输入语言）
不知道如何继续..
