Super I/O chip model or how to find out myself

[Sponge5]

Hello, I need to find out the Super I/O chip model and manufacturer in HP EliteBook 830 g5 in order to control my fan when running Linux. In case you have the Linux driver for it as well I'd like that too :D. Right now my fan is going on max speed even though the CPU is on 15% load, 55C, so I'm a bit desperate.

Relevant sensors-detect output:

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): Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'...               Yes
Found unknown chip with ID 0x2011
Probing for Super-I/O at 0x4e/0x4f

I know it's probably by National Semiconductor, which is under Texas Instruments, and the ID is 0x2011. The probe does nothing though.

HP Elitebook 830 G5 is a series of many machines with many configurations/options. But for CPU, each machine can have an Intel Gen 7th or Gen 8th processor/CPU and its chipset Integrated with processor.

You can ask Intel about your requirement.

Regards.

I've scanned the Intel documents and apparently they do not integrate Super IO with the processor (at least in my case, i5 8250U). The Intel PECI, that gives info to the kernel module Coretemp doesn't give the fan speed, only information from the DTS, that is core temperatures. Which probably means there's a Super IO chip on the mobo which has all the other juicy information. The mobo is HP 83B3. There's a big chance I'm wrong and I'm making a fool of myself here, but I'm desperate and each time I google some equivalent of getting fan speed from PECI/coretemp I get results that reinforce my suspicion.

I still need this to be resolved. The super IO is not integrated with the processor and I need the model. Where can I find it?
