What is a CPU cooler?
The radiator is a device to dissipate heat-prone electronic components in electrical appliances. It is mostly made of aluminum alloy, brass, or bronze into plate-shaped, block-shaped, sheet-shaped, multi-sheet-shaped fins, etc., supplemented by The fan dissipates heat. As far as the heat sink material is concerned, the thermal conductivity of each material is different, and they are arranged from high to low thermal conductivity, which are silver, copper, aluminum, and steel. However, if silver is used as the heat sink, it will be too expensive, so the best solution is to use copper. Although aluminum is much cheaper, it is clear that thermal conductivity is not as good as copper (only about 50% of copper). The commonly used heat sink materials are copper and aluminum alloy.
The heat sink is an extremely important existence in the field of DIY hardware. For example, the CPU in a computer needs to use a relatively large heat sink. Friends who know computers know that the CPU (processor) is the core chip hardware of the computer. Due to its large surface heat, it needs to be equipped with a heat sink for heat dissipation, and the aluminum CPU heat sink came into being.
At present, most desktop and laptop CPUs are equipped with heat sinks. This is mainly because the computer CPU will generate a lot of heat when it is working. If this heat is not dissipated in time, it will cause the computer to freeze, or it may burn the CPU. Therefore, the radiator is always a concern for many hardware DIYs. topic of.
CPU cooler installation
In general, the heat sink should be coated with a layer of thermal grease on the contact surface of the electronic component and the heat sink, so that the heat emitted by the component is more effectively conducted to the heat sink, and the heat on the heat sink is blown to the surrounding air by the fan Go. The same is true for the installation of computer CPU radiators. Before installing the radiators, you need to apply a layer of thermally conductive silicone evenly on the surface of the CPU, and then install the radiators on the surface of the processor.
Types of CPU coolers
According to different heat dissipation methods, computer CPU radiators can be divided into three types: air-cooled, heat pipe, and water-cooled. Among them, air-cooled radiators are the most common, while water-cooled radiators have become popular in recent years.
1. Air-cooled radiator
Air-cooled radiators are currently the most common type of radiators in computer CPU radiators. Their advantages are cheap and easy to use. The air-cooled radiator includes a cooling fan and a heat sink. The principle is to transfer the heat generated by the CPU to the heat sink, and then remove the heat through the fan.
Aluminium Cpu Heat Sink
It should be noted that different types and specifications of CPUs use different heat sinks. For example, AMD processors and Intel processors often use different heat sinks because of different pins. Therefore, when buying a CPU cooler, you need to go according to the CPU pins. Choice, of course, there are many AMD and Intel common CPU coolers on the market, you need to pay attention when buying.
2. Heat pipe radiator
A heat pipe radiator is a heat transfer element with extremely high thermal conductivity. It transfers heat through the evaporation and condensation of liquid in a fully enclosed vacuum tube. Most of these fans are "air-cooled + heat pipe", which has the advantages of air-cooling and heat pipe, and has strong heat dissipation performance, which is relatively common among current high-end mainstream radiators.
Heat pipe CPU heat dissipation, the key lies in this pipe. Many players think that the heat dissipation effect of buying multiple heat pipes will be good, but in fact, it may not be true. The number of heat pipes and the effect of heat dissipation cannot be directly proportional, but more related to their work materials.
3. Water-cooled radiator
The water-cooled radiator uses liquid to forcefully circulate the heat of the radiator under the driving of the pump. Compared with the air cooling, it has the advantages of quietness, stable cooling, little dependence on the environment, and so on. The water-cooled radiator belongs to a relatively high-end radiator at present, with excellent heat dissipation effect, and is popular among DIY game enthusiasts.
As the price of water-cooled radiators continues to fall, water-cooled radiators are now gradually becoming popular.
