What is the main point of view of the CPU performance of the notebook cooling fan? The performance of the CPU cooling fan directly determines the cooling capacity of the notebook. The following is a good analysis by the professional technical personnel of Jingneng [Dongguan Notebook Cooler-Jingneng Electronics]:

　　 The performance of the CPU is mainly seen from these aspects: First, the speed. Second, the shape of the fan blade, and third, the angle of the fan blade and the bearing system. In fact, everyone knows that 40% of the cooling effect of a cooling fan is determined by the speed of the fan. But it does not mean that the faster the speed of the cooling fan, the better. The speed of the fan should be determined by the amount of heat generated by the CPU. The speed of cooling fans of different specifications should be different. The basic principle is: under the premise of the same air volume, the faster the speed of the cooling fan The lower it should be, the lower the noise will be. Generally, the speed between 3500 rpm and 5200 rpm is more conventional.

　　 Therefore, before we buy a fan, it is necessary to understand some of the performance parameters of the CPU fan. Once we know these identification criteria, I believe you will definitely choose a practical and suitable fan.

　　 Warm reminder; better radiators, there will be no burrs on the edges, no deformation of the radiating fins, smooth bottom without cracks, neat appearance, generous shape, quality assurance, anti-counterfeiting marks or other trademarks, etc. In addition, when choosing a radiator, everyone should pay attention to that the bottom of the radiator should not be too thick, because the thermal conductivity of aluminum is not very good, and too thick will affect the heat transfer; in addition, the diversion groove on the surface of the radiator should be denser , This can ensure that the radiator can have a larger contact area with the air, thereby enhancing the heat dissipation effect.

　　 The above are some requirements for the CPU performance of the laptop cooler. Choosing a good CPU cooling fan with suitable performance is an important factor in determining the computer's ability.
