Too hot? Come to the fan's cold knowledge!

Spring is always short. Xiao Bian believes that the upcoming summer season will cause many small partners to face a serious problem, that is, love the machine's heat, buy radiators, enhance heat dissipation, reduce heat noise, etc. It will become the topic of most concern for the little friends. How much do you know about the cold knowledge of the fan? One hundred yuan less than the fan, inside the door can be a lot of Oh!

Is the fan blade odd or even?

The fan's blade estimates that many buddies do not pay special attention to them. Count the number of fan blades in your home and see whether they are odd or even. In the past, radiator fans often saw an even-numbered blade design with two blades facing each other. This type of fan has been used for a long time. For example, when the blades are worn or dust accumulates too much, the center of gravity can easily be displaced. As a result, the fan may suffer from increased fan noise and poor rotation.

The recent fans basically use odd-numbered blades, whose center of gravity is determined by all blades at the same time. Even if individual blades are worn out or accumulate, the center-of-gravity displacement is small, and the noise is much less. Therefore, when Xiao Bian recommends that you buy a radiator, you may wish to count the number of blades first and try to select products with odd number of blades.

At the same time, the fan's blade shape is also very particular, and small partners can look at it. In general, high-speed fans should choose to have radian and swept back blades because they are more suitable for high-speed rotation and are less noisy. The straight fan blade is more suitable for low-speed fans, and its blower covers a large area, and is particularly suitable for use at the top of a case, a laptop stand, and the like.

Straight blades are generally used for low-speed, large-diameter fans. Note that this fan also uses even-numbered blades that are easier to design and manufacture.

More fans = more money!

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

Vertical radiator is good?

There are still some vertical heat sinks that need to install the fan's CPU heat sink. Xiaobian recommends that you also use different directions of rotation when installing, and you can also avoid resonance problems and reduce vibration and noise. In addition, fans facing the memory should choose the suction method, which can suck the dust near the memory as much as possible to reduce the poor contact caused by dust accumulation here.

3 pin or 4 pin, this is not a problem!

Currently, there are two types of power supply ports for PC fans, which are 3-pin and 4-pin designs. Pins with 4-pin connectors are mainly used to transmit some control signals. For example, if there is a fan installed on the interface, the fan speed information is transmitted. Control signals, etc. The 4-pin interface fan's independent detection and control capability is more accurate and safe than the 3-pin interface. Therefore, if the price difference is not large, it is recommended that you choose a 4-pin fan product.

Finally, we must share with you a bit, buckle problem, fans are now fully compatible with the multi-platform, but some product design of the buckle must pay special attention, especially many people online have shared experience, similar to the old money Human 400" products should be carefully selected (the new version has no problem), otherwise it would be a big effort to make a miracle.

The old Xuan ice 400 fan is called "Anti-Human 400" due to problems such as difficult installation and occupation of memory slots.
