CPU fan, also known as cooling fan, is a kind of fan used to cool the CPU. It is provided to the radiator and the chassis and used to quickly transmit the heat of the CPU to the nearby air, so as to play a cooling effect on it. The cooling effect is directly related to the quality of CPU cooling fan and radiating blade. There are many kinds of CPU fans according to the size of installation, type of bearing, number of blades, etc.
As the computer is used for a long time, the noise of CPU fan, graphics card fan, chassis fan, power supply fan and other fans will become larger and larger. Moreover, when the temperature is higher in Summer, the cooling effect of computer hardware will be not very good. Besides, this will also make the fan speeds up and make more noise. Since there are many cpu fan types and cooling fan accessories, how to choose CPU fan? Whether CPU fans are different or mainboard CPU fans are different. How to check the specifications? Today, let's talk about the purchase of CPU fans.
First of all, let's define the interface CPU fan types. In fact, there are three indicators involved here:
Firstly, the power interface of CPU fan comes from the mainboard, so it must be related to the mainboard;
Secondly, the CPU fan radiator should fit the CPU, so it must be related to the specification of CPU;
Thirdly: the CPU fan has a certain volume, so it is also related to the specifications of chassis;
As it is easier that the power supply can be standardized, the first indicator can be ignored, and the second indicator and the third indicator are key indicators. In addition, there is also a very important index for the CPU fan, which is the bearing. The common bearings include oil bearing, double ball bearing, single ball bearing, hydraulic bearing and raffle bearing. In addition, there are nano ceramic bearings, magnetic bearings and fluid protection system bearings, but they are relatively expensive and rare in the market.
For different types of fan bearings, there are great differences in noise control. When buying the cooling fan, we can generally get the relevant bearing information from the English letters of its tag. Reading this information is helpful for us to choose the products suitable for our own needs.
