Why is the cold enough to meet the basic heat dissipation needs of the CPU

    The air -cooled heat dissipation method is a CPU cooling method based on metal thermal conduction and air heat convection method.This method is installed on the CPU, and a small fan is installed on the heat sink, allowing the air to force the air to take away the heat of the CPU to work.Most of the current motherboards have intelligent fan control functions. When the CPU temperature is not high (such as 37 ° C), the CPU fan speed is controlled between 1000-2000 rpm per minute. When the CPU is at high temperature, the fan can run at full speed at full speed.3000-5000 rpm per minute.
    The air -cooled method is generally adopted because of its simple, practical and low price.However, the cooling efficiency of the cooling method is low, and it can only discharge 60%of the calories of the CPU at most. It also faces many restrictions in the application process, mainly including:
    1) The maximum temperature of the CPU does not exceed 90 ° C;
    2) The ambient temperature should not exceed 40 ° C;
    3) The power of the CPU should not exceed 200W;
    4) The fan air flow unit should not be greater than 40CFRO (Cubic Feet Per MIN-UTE).
