m16 R1, Ubuntu 24.04, sensors technical explanation

Hello guys! Im an embedded developer and always love to understand my entire hardware. Recentlly I bought one AW m16 r1 (i9 13900HX + 4060) and using with dual boot (<Not supported by Dell. DELL-Admin> Ubuntu 24.04 + Windows 11).

I trying to understand 'lm-sensors' output from Ubuntu 24.04 and have two questions:

1. Where are temperature sensors and what which means?

2. How can I control fan speed? Pwmconfig not working :(

What is "dell_smm-virtual-0"? What does each "tempX" mean? Where is it physically located?

What is "dell_dvv-virtual-0"? What does each "ambient temperature" mean? Where is it physically located?

What is the difference between the CPU temperature in "dell_dvv-virtua-0" and "coretemp-isa-0000"? Why are they different? Which should I trust more?


I cant find any information about where sensors are located in alienware datasheet available on dell website. But I really want to know this information to create some awsome monitoring tools and so on. Please help me with specific informations!
