Which is better, air cooling or water cooling?

The air is cooler.

Air-cooled heat dissipation is the most common and very simple, that is, using a fan to take away the heat absorbed by the radiator. It has the advantages of relatively low price and simple installation, but it is highly dependent on the environment. For example, when the temperature rises and overclocking, its heat dissipation performance will be greatly affected.

Water cooling is a forced circulation of liquid driven by a pump, which takes away the heat of the radiator. The heat dissipation performance of water-cooled radiator is directly proportional to the flow rate of coolant (water or other liquid), which is related to the pump power of refrigeration system. Moreover, the large heat capacity of water makes the water-cooled refrigeration system have good heat load capacity. But the price of heat pipe and liquid cooling is relatively high, and the installation is more troublesome.

Selection of radiator:

After talking about the types of radiators, it is time to say how to choose. The main function of radiator is to dissipate heat. The price is on the rise, and the cheap water-cooled radiator is really easy for players to shake, but if the author tells you that the effect of cheap water-cooled radiator is similar to that of ordinary air cooling. Here comes the problem again. When radiators are used for home use, there are many additional requirements, the most important of which is noise.

As the most mature radiator, air cooling has reached a certain level in all aspects of technology and is also the most widely used. Let's compare water cooling. First of all, there will be a sound of pumping water when cooling water, which is inevitable. If there is no water pump to keep the water flowing, then water cooling will have no heat dissipation effect.

The second is the fan on the cold row. The fan on the cold row is also noisy, so there must be a fan on the cold row, because most water pipes with integrated water cooling are relatively short, and the distance in which water flows is not natural enough to dissipate heat. After flowing into the cold row, heat is retained on the cold row through heat transfer. At this time, the heat dissipation of the fan is extremely important. For such a short distance, it is completely impossible to ensure the stability of cold liquid without this fan.

Water cooling adds two noise sources: water pump and fan. As long as the quality is not too bad, it can be said that the noise at the same price is better than air cooling.
