Fan spinning at maximum speed immediately upon plugging in the charger.
Acting as a dedicated microcontroller, this chip handles tasks that the main CPU does not manage directly, such as:
Whether you are a BIOS engineer, a hardware hacker, or a repair technician, understanding the unlocks the full potential of this chip—from controlling external peripherals to monitoring system health.
It reads temperatures from thermal sensors and dynamically adjusts Pulse Width Modulation (PWM) fan speeds to prevent overheating.
