Fans not detected on my HP Z420 (running even if idle)

I have a HP Z420 workstation and the fan is running not super loud but annoying.
My cpu temperature is < 40 deg.

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +37.0°C  (high = +81.0°C, crit = +91.0°C)
Core 0:        +34.0°C  (high = +81.0°C, crit = +91.0°C)
Core 1:        +33.0°C  (high = +81.0°C, crit = +91.0°C)
Core 2:        +33.0°C  (high = +81.0°C, crit = +91.0°C)
Core 3:        +36.0°C  (high = +81.0°C, crit = +91.0°C)

Core 5:        +36.0°C  (high = +81.0°C, crit = +91.0°C)

This is my sensors detect

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):

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

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

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.

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

Do you want to overwrite /etc/conf.d/lm_sensors? (YES/no):
Unloading i2c-dev... OK
Unloading cpuid... OK

Is it possible to see the fan speeds? I wasn't able to find anything regarding the motherboard.
What does this mean:

Trying family `National Semiconductor/ITE'...               Yes                                                                                                                                   
Found unknown chip with ID 0x1c11      

Does it mean that I should run some `modprobe` command to install a driver that supports it? If yes, how.

Thanks in advance. Sorry I'm a newbie

Re: Fans not detected on my HP Z420 (running even if idle)

Your temp seem normal. As long as you dont see a strange minus temp in sensors you are good.

1 There is a setting in bios for the fans when idle, maybe they are on highest setting,
2 Also possible issue is common sensor failure located in frontpanel.
3 I swapped my standard factory fans for quiter but the standard fans have 4 black wires, from the pinout is difficult to see which is pwm, tmp etc.
That triggers bios also to keep fans at highest speed. But the you should see a minus or very high temp in sensors as in my Z800

So I think(hope) you can solve with 1
