Wait what? How is this the OS's sole role?
What is the mcu the rpi5 has onboard even for?

Embedded Design.
A PWM driver (or a hardware timer) will handle the nanosecond-to-nanosecond wait states and counts, but the OS has to still setup the hardware timer to send the right PWM wave down to the system.
Besides, the OS should have some degree of custom fan controls for any modern computer, embedded or not. My PC can control all of my fans for example.
