Super IO chip model

[Sponge5]

I would like to use this thread to bump this old one, which got locked since I didn't use it for a month. I only now realised that I need to tag people for them to see my reply. My problem is still not resolved even though I'm fairly sure that I'm asking in the right place. My fan is blasting at the time of typing this (15% CPU load).

This is not really my forte but I reached out to a collegue and this was his response. 

This particular laptop is a Windows only box and therefore may contain some proprietary chips on the MB.  It is possible that the probe is actually misreporting one of these proprietary chips as Super I/O.  Since HP has no Linux support for the EliteBook 830 G5 there would be not direct drivers available.

"That said, again we come to the BIOS. The customer should be sure to get on the latest release of the BIOS firmware for the unit. Once that is in place, the customer should look for any options for APCI control or power management. If present, there may be an option to have it be BIOS controlled or OS controlled. He can try that on either setting to see which works better."

I have updated the BIOS and before even changing any settings I noticed that the fan gets activated for shorter periods of time and at a lower speed. Progress! The intervals are still quite short to my liking though, so after scanning through the BIOS settings I found:

In Power Management Options:

- Runtime Power Management

- Extended Idle Power States

...

- Power Control

...

In System Options

...

- Dynamic Platform and Thermal Framework (DPTF)

I have all of those checked, will report when I try some some checked off. I suspect I still won't see the fan speeds in 

sensors

output (lm-sensors), which would make fan control from the OS impossible.

The SuperIO has to be on the Mobo somewhere, the information about fan speed doesn't go into the processor. That wouldn't make sense. Processor has to communicate with it just like I want to.

The Mobo is from HP, no? HP has to know what they put on their Mobo...

It doesn't matter the chip's proprietary or not, communication with SuperIO is straightforward afaik, I believe I could write my own simple fan control driver or at least help out the guys from lm-sensors to add support for this machine (and others with the same chip).

Hi, could you help me find the reference for my motherboard (HP 83B3) I seriously need to know the chip model...
