CPU Fan Performance Introduction

The main performance of the fan is reflected in the following aspects: speed, blade shape, blade angle and bearing system. In general, the fan speed is indicated on the radiator manual. Generally speaking, 30% of the heat dissipation effect of the radiator depends on the fan speed. But the fan speed is not the higher the better. The correct fan speed should be determined according to the heat generated by the CPU. The speed selection of fans of different specifications should be differentiated. The basic principle is: under the premise of generating the same air volume, the larger the fan, the lower the speed should be, and the noise will also be smaller. Generally, the speed between 3500 and 5200 rpm is more conventional.
The greater the power, the stronger the fan wind force and the better the heat dissipation effect. The power of the fan is directly related to the fan speed, that is, the higher the fan speed, the stronger the fan. Most of the fans sold in the computer market are DC 12V, and the power ranges from 0.X W to 5.04W, so the power needs to be selected according to the heat generated by your CPU. I would like to remind you that you cannot emphasize high power one-sidedly. You only need to match the power of the CPU itself. If the power is too large, not only will the cooling effect not be greatly enhanced, but it may increase the workload of the computer and eventually shorten the life of the CPU and fan. Therefore, when choosing the power of the CPU, you should measure the "heat".
A better radiator will not have burrs on the edges, the cooling fins will not be deformed, the bottom will be smooth and without cracks, the appearance will be neat, the shape will be generous, there will be a quality guarantee, and there will be anti-counterfeiting marks or other characteristic trademarks. In addition, when choosing a radiator, you should also pay attention to the fact 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 guide grooves on the surface of the radiator should be denser, so as to ensure that the radiator can have a larger contact area with the air, thereby enhancing the heat dissipation effect.
