The invention discloses a PID fan regulation and control strategy implement method and
system based on the environment temperature and belongs to the technical field of CPU heat dissipation. According to the PID fan regulation and control strategy implement method and
system, a Kp value is changed along with the change of the environment temperature, and the environment temperature is dynamically regulated through a fan regulation and control strategy. The technical scheme comprises (1) the PID fan regulation and control strategy implement method based on the environment temperature and (2) the PID fan regulation and control strategy
system based on the environment temperature, specifically, according to the method, in the CPU operation process, the current environment temperature is
read through an air
inlet temperature sensor, the Kp value in the fan regulation and control strategy is determined according to the environment temperature, and the PID fan regulation and control strategy is dynamically regulated; and the system comprises the air
inlet temperature sensor, a main board management controller and a fan management module, wherein the air
inlet temperature sensor sends data to the main board management controller through an I2C
bus, and the main board management controller sends the data to the fan management module through an I2C
bus.
