Editor to share with you the performance analysis of the CPU fan in the computer, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

CPU fan, also known as cooling fan, is a fan used to radiate CPU, provided to radiators and chassis, is to use them to quickly transmit the heat of CPU and blow into the nearby air, play a cooling effect. The cooling effect is directly related to the quality of CPU cooling fan and heat sink.

The cpu fan blows in, because the CPU is affixed to the radiator, the CPU fan blows air into the radiator to cool the air, and the heat transferred from the CPU to the radiator also radiates with the convection of the air.

Performance of CPU fans

The main performance of the fan is reflected from the following aspects: speed, blade shape, blade angle and bearing system. In general, the speed of the fan is indicated on the specification of the radiator. Generally speaking, 30% of the cooling effect of the radiator depends on the speed of the fan. But the fan is not the higher the speed the better. The correct fan speed should be determined according to the calorific value of CPU, and the selection of fan speed of different specifications should be distinguished. The basic principle is: under the premise of generating the same air volume, the larger the fan speed is, the lower the speed should be, and the noise will also be lower. Generally, the speed between 3500 and 5200 revolutions is more conventional.

The greater the power, the stronger the wind power of the fan, the better the cooling effect. The power of the fan is directly related to the speed of the fan, that is to say, the higher the speed of the fan, the more powerful the fan. Most of the fans sold on the computer market are DC 12V, and the power ranges from 0.X W to 5.04W, so the power needs to be chosen according to your CPU calorific value. In particular, to remind you that one-sided emphasis on high power, just need to match the power of the CPU itself, if the power is too large, not only the cooling effect is not greatly enhanced, but may increase the workload of the computer, and ultimately shorten the life of CPU and fans. Therefore, in the choice of CPU power size, should be measured "hot".

The better radiator, the edge will not appear burr phenomenon, the heat dissipation fin has no deformation, the bottom is smooth without crack, the appearance is neat, the shape is generous, has the warranty, has the anti-counterfeiting mark or other characteristic trademark and so on. In addition, when choosing the radiator, we should also pay attention to that the bottom of the radiator can not be too thick, because the thermal conductivity of aluminum is not very good, 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, so as to enhance the heat dissipation effect.

The above is all the contents of the article "performance Analysis of CPU fans in computers". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
