Aluminum cpu heat sink cooling method
As far as the heat dissipation method is concerned, there are various heat dissipation methods for the CPU heat sink. The most common ones are currently divided into active heat sinks and passive heat sinks.
1. Active radiator
To put it simply, an active heat sink is a heat sink with external force to assist heat dissipation, such as a fan and water cooling liquid. These are all classified as active heat dissipation, which is also the most common heat dissipation method for computer CPU heat sinks.
2. Passive radiator
The passive radiator refers to a heat dissipation method that does not rely on external force, only conducts through a metal sheet, and then dissipates heat energy into the air. This heat dissipation method is relatively not particularly good, mainly for some CPUs with low heat generation. Will be used in.
Active radiators and passive radiators have their own advantages. The former has a good heat dissipation effect, which can quickly remove the heat generated by the CPU, but the disadvantage is that there is noise. Although the water-cooled radiator has no noise, it has a higher cost and belongs to a high-end radiator. The price is relatively expensive; while the advantage of passive cooling is low cost and no noise, but the disadvantage is that the cooling effect is worse than the active type, which is easy to cause heat accumulation At present, it is mainly used in components with less heat, such as mobile phone CPU is basically this passive cooling method.
That kind of CPU cooler is good
If the price factor is not taken into account, among the air-cooled radiators, heat pipe radiators and water pipe radiators, the heat dissipation performance of the water pipe radiator is the best.
The water pipe radiator uses the cooling liquid to forcefully circulate the heat of the radiator under the driving of the pump. Compared with air cooling, it has the advantages of quietness, stable temperature reduction, and little dependence on the environment. The disadvantage is that the price is much more expensive than ordinary air-cooled radiators.
In addition to water-cooled radiators, heat pipe radiators have relatively better heat dissipation performance than air-cooled radiators. This is mainly because water-cooled radiators not only achieve the effect of air cooling, but also add heat pipes to assist in heat dissipation. It is better than air cooling, and the price is between air cooling and water cooling.
Although the cooling performance of the air-cooled radiator is the worst among the three, but for most CPUs that are not very heat-generating, the heat dissipation capacity is basically sufficient, and the price is cheap, so it is currently the ordinary CPU radiator. most common.

How to choose aluminum cpu heat sink for sale
Different brands and different workmanship radiators often have different prices, and their cooling performance will naturally vary. The following uses the most common air-cooled radiator as an example to teach you how to choose a radiator.
speed of the fan
Generally, the higher the fan speed, the greater the air volume it provides to the CPU, and the better the air convection effect. However, the extremely high speed will bring heat and increase the wear of the fan, so it is necessary to strike a balance between the two.
Heat sink material
At present, the air-cooled radiator is widely used as a heat sink with low price and good heat dissipation effect. At the same time, in order to improve the overall heat dissipation effect of the heat sink, the middle and high-end heat sinks use a copper medium with better heat dissipation in the place in contact with the CPU heat dissipation core.
Fan noise
Generally, the fan rotates at a high speed during the working process, and this sound is generated. It is mainly affected by the fan bearings and blades. The louder the sound, the greater the noise generated. Therefore, when choosing the CPU, you must choose the noise Smaller.
Fan exhaust
Fan exhaust volume is an important indicator to measure the performance of a fan. The angle of the fan blades, fan speed, etc. are all determinants of the cooling fan's exhaust air volume.
