[0034] At present, the commonly used method in the design of heat dissipation system is to increase the speed and air volume of the fan to improve the heat dissipation efficiency. This strategy can effectively take away more heat and keep the system temperature within a safe range, thereby ensuring the continuous and efficient operation of the hardware. However, the traditional fan board card design often ignores the maintenance convenience, and once the fan fails, the replacement process is tedious and time-consuming, which is a obvious shortcoming in the data center environment with high requirements for stability and availability.
