A secondary development and revision method for the motherboard based on heat management, wherein the secondary development and revision is carried out according to the public PCB issued by the motherboard chip supplier, euthermic chips are classified according to the size of heat and operating temperature range of the euthermic chips to match the power of the heat dissipation device used; at the same time, taking into account the size specifications and position of connector, in the condition of forming a smooth air flow channel as far as possible, the euthermic chips are arranged on both sides of the motherboard. The disclosure realizes the scattered arrangement of the heating components on the motherboard, improves the heat accumulation condition inside the product in essence, makes the cooling channel more direct, and improves the heat dissipation cost, power consumption, conduction medium and reliability of the product.
