Spring is always short, especially in the south of the companions, must have a deep experience, have not seen the footsteps of spring, has entered the summer. There is also a serious problem that comes with summer, that is, the heat dissipation of love machine. What kind of radiator should we choose? It will become the most important concern of the small partners. How much do you know about fan cooling? There are many doors inside the cooling fan.

Is the fan blade odd or even?

Fan blades are estimated many small partners have not paid attention to, carefully count your fan blades, see if it is odd or even? In the past, even number of blades often appeared in heat dissipation fans, and the two blades are opposite. This kind of fan has been used for a long time, for example, the blade is worn or accumulates too much dust, the center of gravity is easy to shift, so that the fan will have increased noise, poor rotation.

Now fans basically use odd number of blades, whose center of gravity is determined by all blades at the same time. Even if individual blades wear or accumulate ash, the center of gravity offset is relatively small, of course, the noise is much smaller. Therefore, it is suggested that when you buy heat dissipation fans, you might as well count the number of blades first, and try to choose fans with odd blades.

At the same time, the shape of the fan blade is also very exquisite. Generally speaking, high-speed fans should choose the fan blade with radian and swept back, because they are more suitable for high-speed rotation and low noise. Flat fan blade is more suitable for low-speed fan, its blown area is large, especially suitable for use at the top of the chassis, notebook bracket and other places.

Should we choose balls or oily ones?

The cooling fan has two-week bearings, one is ball bearing, the other is oil bearing. The ball bearing has single ball and double ball. Its advantage is longer service life and stability. Oil bearing is more quiet, but affected by the use of environmental impact, oil bearing is not suitable for all products. Everyone can follow up the selection of their own machine when choosing and purchasing.

Front or side wind?

Heat dissipation fans have front air outlet box, side air outlet blower, and full air outlet disc. Follow up your machine needs and select the appropriate outlet.

More fans = more money

The use of multiple fans in processors and graphics card radiators is a development trend, but many small partners probably did not think that if used improperly, multiple fans may not be able to significantly improve the heat dissipation capacity, but may cause particularly obvious vibration, noise and other issues. On some multi-fan graphics cards, we can see the reverse rotation or different size of the fan configuration, they can avoid resonance problems, reduce vibration and noise.

Three or four?

At present, PC fans only need two kinds of power supply interfaces, which are designed with three pins and four pins respectively. The extra pins of the four pins are mainly used to transmit some control signals, such as judging whether the fan is installed on this interface or not, transmitting the fan speed information is very control signal, etc. The independent detection and control ability of 4-pin interface fan is more accurate and safe than that of 3-pin interface. Therefore, it is recommended that you choose 4-pin interface fan products when there is little difference in price.
