Although the CPU heat sink is not an expensive accessory, if there is no CPU heat sink, the CPU will generate a lot of heat and will reduce the frequency by itself at high temperatures, which not only threatens the safety of other parts of the motherboard, but also affects its performance. There are currently three types of CPU heat sinks on the market, air-cooled, integrated water-cooled, and split water-cooled. So how to choose?

Air-cooled heat sink

Air-cooled heat sink is the most commonly used heat sink, which is composed of copper pipes, cooling fins and fans. The CPU is in contact with the heat sink base and conducts heat through silicone grease. When heat is generated, the heat will be transferred to the heat sink fins along the copper pipe, and then the airflow of the fan is used to blow away the heat on the heat sink fins to achieve The effect of cooling the CPU.

Integrated water-cooled heat sink

Water-cooled heat sinks will become more popular in the past few years. The integrated water-cooled heat sink is relatively simple to install, just screw the screws. The integrated water-cooled heat sink is composed of a cold exhaust and a radiator head. The integrated water-cooled heat sink is basically all fixed when it leaves the factory, and it is relatively safe, so the installation is very simple, and the heat dissipation capacity is much better than that of the air-cooled heat sink.

Split type water-cooled heat sink

Split-type water-cooled heat sink is mainly for high-end players who like to do it. The cost is relatively high. It mainly consists of water block, coolant, water pump, pipes, water tank and cold exhaust.

In high-power products such as large servers, liquid cooling technology is widely used. Liquid cooling technology is to use a liquid with a high specific heat capacity as a heat transfer tool to transfer the heat generated when a high-power product is running, so that the product can operate normally.

According to the contact method between the liquid and the heating device, liquid cooling is mainly divided into cold plate liquid cooling and immersion liquid cooling.

Cold plate liquid cooling

The main heating element of cold plate liquid cooling is fixed on the liquid cold plate, and the liquid flowing through the liquid cold plate takes away the heat to achieve the purpose of heat dissipation. It is a typical indirect contact liquid cooling. Since other heating components such as hard disks and power supplies still require fans to drive air to dissipate heat, the current cold-plate liquid-cooled server is also called a gas-liquid dual-channel server. The development of cold plate liquid cooling technology is relatively mature. IBM and domestic Sugon respectively demonstrated their cold plate liquid cooling servers and applications. The cold-plate liquid-cooled server has little effect on the current data center architecture. It has the characteristics of low noise, high energy efficiency, and low total cost of ownership, and can solve the heat dissipation problem of higher heat density data centers.

What Is A Heat Pipe?

A heatsink is a device which aptly transfers heat from an electronic device to a fluid, which can either be air or even other liquid coolant. It is due to the amazing function of this component that you can check the external heat or surface heat of an electronic device. 

There are many kinds of heatsinks; however, in this piece of information I will be telling you about heatpipe heatsinks, extruded heatsinks and custom heatsinks.

1. Heatpipe heatsinks: This kind of heatsink works upon the general principle of thermal conductivity along phase transition while carrying or transferring heat from an electric component to fluid media. You will commonly find this type in laptops. Now let me tell you about the process of heat transfer, the major part of it takes place at the interface of liquid coolant plus the heated surface.

 With the help of a heat pipe system, it lets the liquid absorb or gather as much of heat as possible. This finally leads to a phase where the liquid is changed into vapors. The vapors then travel via heatpipe sink and then reach cold interface and after that due to dissipation of heat, it changes to liquid again.

2. Extruded heatsink: This one offers a larger surface area to remove or transfer heat from devices as compared to a heatpipe heatsinks. You will find this one in high-power consuming semiconductors, IGBTs, diodes,   RF power transistors, thyristor modules, power amplifiers, inverter power modules plus many other devices. 

For a component which offers such a vast application, it becomes important for a buyer to completely understand his/her needs and compliance of heatsink with it.

3. Custom heatsinks: This type generally includes  heatpipe assemblies, stacked and folded fin heatsinks, extrusion heatsinks, vapor chamber heatsinks, active heatsink, optics heatsinks, skived fin heatsink and PCI-E heatsinks.  Aside from this, you can also get advanced metal fabrication for enhancing function of your custom heatsink. They are perfect for all those people whose requirements are not met by the standard heatsinks available in the market.
