这很烦人,我想这是自上次更新以来发生的,CPU 风扇运转声音更大,这意味着可能比平时更快。这确实是 CPU 的问题,而不是 NVIDIA 风扇的问题。我已经尝试了一些方法。
我修改了 grub 配置:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force acpi_osi=linux"
GRUB_CMDLINE_LINUX="acpi_enforce_resources=lax"
我读到第一个是针对有缺陷的 BIOS,第二个是 it87 内核模块的问题。sensors-detect 希望我加载这个模块,但它无法加载(modprobe it87 最终严重:插入时出错87,所以第二行解决了它)
我也清洁了风扇和 CPU,虽然它们没有那么多灰尘,但也没有帮助。
虽然我想让自动检测再次运行,但我也尝试通过 fancontrol 来控制它。但不幸的是,这行不通。我明白了...
PWM 255 FAN 0
Fan Stopped at PWM = 255
This fan appears to stop when the PWM is enabled;
perhaps the fan input shares a pin with the PWM output
on the sensor chip.
You cannot control this fan with this PWM output.
我已经尝试加载以前的内核,但没有结果。顺便说一句,我的 CPU 使用率只有 4%,所以没有运行任何繁重的进程。
传感器输出(我不确定为什么那些 ISA 适配器有这些奇怪的值。也许这是问题的一部分?)

答案1
用户 Psusi 说得对,风扇的轴承坏了(我用手指转风扇时感觉到了)。我换了风扇,就没声音了。
