CPU heatsink What kind of good

In the DIY computer field, many players in the installation, attention is often focused on the computer performance of the CPU, graphics, motherboards, memory, hard disk and other core hardware, on the chassis power, radiator and other hardware often do not care too much. Because of this, some friends assembled computers are often equipped with some of the inferior radiator, cottage chassis power supply and so on, in the future when used, it is very easy to have a variety of poor heat dissipation, computer without cause restart, or even blue screen and so on.

In fact, in DIY computers, the bucket effect is particularly important to pay attention to, ignoring the radiator, power and other hardware, may lead to the entire host platform performance, stability and even life, have an impact. Today, the computer Pepsi Network is mainly to share the computer CPU heatsink selection, in the purchase, should pay attention to which and so on.

One, what is the CPU heatsink?

Radiator is a kind of electrical appliances in the heat-sensitive electronic components of the device, mostly made of aluminum alloy, brass or bronze plate-like, block, flake, many pieces of different shapes such as heat sink, supplemented by the fan for cooling.

What is CPU heatsink

The heatsink is an extremely important presence in the DIY hardware field, such as the CPU in the computer using a fairly large heatsink. Understand the computer's friends are only, CPU (processor) is the computer's most core chip hardware, due to its surface heat is large, and therefore need to be equipped with radiators for cooling, the CPU radiator was born.

Most desktop computers and laptops are equipped with radiators on the CPU at the moment. This is mainly because the computer CPU in the work will produce a lot of heat, if not the heat emitted out in time, light will cause the computer crashes, heavy may be the CPU burned, so the radiator is always a lot of hardware DIY are more concerned about the topic.

Second, the CPU heatsink installation

General heatsink in use in the electronic components and heatsink contact surface coated with a layer of thermal grease, so that the heat emitted by the components more effective conduction to the heat sink, in the fan will heat dissipation on the fins scattered to the surrounding air.

And the computer CPU radiator installation is also so, before installing the radiator, need to apply evenly on the CPU surface on a layer of thermal silica gel, and then install the radiator on the processor surface.

Third, the CPU heat sink classification

Computer CPU Radiator According to its different heat dissipation, can be divided into air-cooled, heat pipe and water-cooled three kinds, of which air-cooled radiator is the most common, and water-cooled is the beginning of the popular high-end radiator.

1. Air Cooled Radiator

Air-Cooled radiator is the current computer CPU radiator, the most common type of radiator, its advantages are cheap and easy to use. The air-cooled radiator includes a cooling fan and a heatsink. The principle is to transfer the heat from the CPU to the heatsink and then take the heat away through the fan.

It should be noted that different types and specifications of the CPU used by different radiators, such as the AMD processor with the Intel processor because of different pins, often use a different radiator, so the CPU to buy the heat sink, you need to choose according to the CPU's pins, Of course, there are also many AMD and Intel common CPU radiators in the market, when buying, need to pay attention to.

2. Heat Pipe Radiator

The heat pipe radiator is a heat transfer element with extremely high thermal conductivity, which transmits heat through evaporation and condensation of the liquid in the fully enclosed vacuum tube. Most of the fans are "air-cooled + heat pipe" sex, both air-cooled and heat pipe advantages, has a strong thermal performance, is currently in the high-end mainstream radiator is more common.

Heat pipe CPU heat, the key is on this tube. Many players believe that the thermal effect of purchasing multiple heat pipes will be good, in fact, may not be true. The number of heat pipe and heat dissipation effect can not be proportional, and more is related to its workmanship materials.

3, water-cooled Radiator

water-cooled Radiator is the use of liquid in the pump driven by forced circulation to take away the heat of the radiator, compared with the wind cooling with quiet, cooling stability, small environmental dependence and so on. Water-cooled Radiator belongs to the high-end of a radiator, cooling effect outstanding, by DIY game enthusiasts hot selection.

As the price of water-cooled radiators continues to fall, water-cooled radiators are becoming increasingly popular.

Four, the CPU radiator cooling mode

In terms of heat dissipation, the CPU heatsink has a variety of cooling methods, the most common is mainly divided into active radiator and passive radiator.

1, the active type radiator

In simple terms, the active radiator is an external heat sink, such as fans, water cooled liquid, which are classified as active heat dissipation, which is the most common computer CPU heat dissipation method.

2. Passive Radiator

And the passive radiator refers to not rely on external forces, only through the metal plate conduction, and then the heat emitted into the air heat dissipation way, this heat dissipation, heat dissipation ability is relatively not particularly good, mainly for some of the lower calorific value of the CPU will be used.

Passive radiator

The active radiator and the passive radiator actually each has the merit, the former heat dissipation effect is good, may quickly the CPU produces the heat quickly to take away, but the shortcoming is has the noise. Although the water-cooled radiator does not have the noise, but the cost is high, belongs to the high-end radiator one kind, the price is more expensive; the advantage of the passive heat dissipation is the low cost and no noise, but the disadvantage is that the heat dissipation effect is worse than the active one, it is easy to cause the heat accumulation, such as mobile phone CPU is basically the passive heat dissipation mode.

Five, CPU radiator which kind of good?

If the price factor is not considered, in the air-cooled radiator, heat pipe radiator and water pipe radiator, the cooling performance of the water pipe radiator is the best.

The water pipe radiator uses the cooling liquid to force the circulation to take away the radiator the heat under the pump drive, compares with the wind cooling to have the quiet, the cooling stability, to the environment dependence small and so on the advantage. The disadvantage is that the price is much more expensive than the common air-cooled radiator.

In addition to water-cooled radiator, heat pipe radiator performance relative to the cooling, cooler than the air-cooled radiator, which mainly lies in the water cooling radiator not only to achieve the effect of air-cooled, but also added heat pipe auxiliary heat, so the cooling effect is better than the wind cold, the price is between the wind and water cooling.

Although the cooling performance in the three in the average is the worst, but for most of the heat is not very large CPU, the cooling capacity of the basic enough, combined with cheap prices, so the current common CPU radiator most common.

Vi. How to select the CPU heatsink

Different brands, different work of the radiator, the price is often different, its thermal performance will naturally vary. The following is the most common air-cooled radiator, for example, to teach you how to choose the radiator.

Fan speed

The higher the fan speed, the greater the amount of airflow it provides to the CPU, and the better the air convection effect will be. But a very high speed will bring heat and increase the wear and tear of the fan, so it is necessary to strike a balance between the two.

Heatsink Material

At present, air-cooled radiator is widely used in the low price, good cooling effect of aluminum alloy as a heat sink. At the same time, in order to improve the radiator's overall cooling effect, the middle and high-end radiator in contact with the core of the CPU heat dissipation with better copper media.

Fan noise

General fan working process are high-speed rotation, which will be issued by the sound, it is mainly affected by fan bearings and blades, the larger the sound, the greater the noise generated, so in the selection of the CPU, must choose a smaller noise.

Fan Exhaust Air Volume

Fan exhaust air is an important indicator to measure the performance of a fan. The angle of the fan blade, the fan speed and so on are the determining factors that affect the exhaust air volume of the cooling fan.

Radiator Brand

The brand is also felt that the radiator is very important one factor, the big brand has the mature production line, the workmanship and the product quality aspect is relatively more guaranteed.

The current CPU radiator brand mainly includes: Kyushu winds, cool Extreme, overclocking Three, the Ultimate, Titanic, Game titans, Hyenas, Zaman, pirate ship, Yue Lin, first horse, Owls, patriots, Czech, etc., the top six are currently more well-known brands, products more reliable.

Price

Even the different brands, different grades of products will have different prices, after all, the cost of the product is placed there.

In the current market, 20 yuan-50 of the radiator between the majority of the entry-level air-cooled radiator, thermal performance in general, can meet the majority of power consumption is not high dual-core CPU or four-core CPU heatsink requirements.

And the general i5 or AMD eight core processors, it is recommended to buy about 100 yuan of air-cooled or heat pipe radiator, and high-end CPU is recommended to use more than hundred heat pipe radiator or consider to buy some 300 yuan cooling water, experience more excellent heat dissipation.

High-end water-cooled radiator Night effect

It is worth mentioning that if the purchase of the boxed CPU is a self-contained radiator, if the purchase is a bulk CPU, you will need to purchase a separate heatsink. Of course, if you are the hardware DIYer, in order to pursue better thermal performance, will generally buy some of the radiator alone, for ordinary users, the general purchase of the boxed CPU with the radiator can meet the demand.

Although many hardware DIYer focus only on CPU and video card performance, there is little attention to the heatsink that does not relate to performance. However, CPU heat sink on the stable operation of the CPU plays a decisive role in the Assembly of computers, it is best to buy a good number of radiators, which for some people like to play large games or large-scale applications of users, especially important.
