如何查看 Dell OptiPlex 3070 上的 CPU 风扇速度?

如何查看 Dell OptiPlex 3070 上的 CPU 风扇速度?

我有一台运行 Ubuntu Server 的 Dell OptiPlex 3070。它是这台计算机的较小尺寸版本。我想知道如何读取系统中单个风扇的当前风扇速度(我假设这是 CPU 风扇)。这是输出,sensors没有列出风扇速度。

$ sensors

Sensor 2:     +30.9°C  (low  = -273.1°C, high = +65261.8°C)

这是我正在运行的 Ubuntu 版本:

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): YES

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): YES
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'...               No

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): YES
Probing for `IPMI BMC KCS' at 0xca0...                      No
Probing for `IPMI BMC SMIC' at 0xca8...                     No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): YES
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' at 0x290...                   No
Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): YES
Using driver `i2c-i801' for device 0000:00:1f.4: Cannon Lake-H (PCH)

Next adapter: SMBus I801 adapter at efa0 (i2c-0)
Do you want to scan it? (YES/no/selectively): YES
Client found at address 0x50
Handled by driver `ee1004' (already loaded), chip type `ee1004'
    (note: this is probably NOT a sensor chip!)
Client found at address 0x52
Probing for `Analog Devices ADM1033'...                     No
Probing for `Analog Devices ADM1034'...                     No
Probing for `SPD EEPROM'...                                 Yes
    (confidence 8, not a hardware monitoring chip)

Next adapter: i915 gmbus dpb (i2c-1)
Do you want to scan it? (yes/NO/selectively): yes

Next adapter: i915 gmbus dpc (i2c-2)
Do you want to scan it? (yes/NO/selectively): yes

Next adapter: i915 gmbus misc (i2c-3)
Do you want to scan it? (yes/NO/selectively): yes

Next adapter: i915 gmbus dpd (i2c-4)
Do you want to scan it? (yes/NO/selectively): yes

Next adapter: AUX C/DDI C/PHY C (i2c-5)
Do you want to scan it? (yes/NO/selectively): yes

Next adapter: AUX D/DDI D/PHY D (i2c-6)
Do you want to scan it? (yes/NO/selectively): yes


Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

Do you want to add these lines automatically to /etc/modules? (yes/NO)

Unloading cpuid... OK

我找到了这个并尝试了一下sudo modprobe i8k force=1。运行该命令后,输出如下sensors
