Which Linux kernel modules are related to fan speed, temperature monitoring and power management. The goal of my question is to provide a starting point for understanding which Linux kernel modules will help a laptop better perform in regards to power management when on battery, as well as heat management to prevent overheating.

lm-sensors is the standard module for monitoring hardware components.

There are kernel modules that use ACPI for power management but I think the pm-utils package has become the more common way to control it.
