New User how to choose a good water cooling radiator?

A complete kit of water cooling radiator, must have water pump, water tank, cold head, cold exhaust, fans, pipes, joints, water cooling liquid. These are indispensable, as for those flow indicators, exhaust valves, discharge valves, etc., have or not affect the whole system. 

A kit of water-cooled radiator, the heat dissipation capacity is determined by the heat sink. Below, we will be in the purchase of radiator, need to pay attention to the problem, and why it has such a big impact on the heat dissipation performance to answer.

1. choose the right size for the radiator. 

The size of the radiator is often decided according to the size of the fan, 120, 240, 360 and so on are more common radiator models. 

These specifications for the radiator size are based on the number of fans that can be installed. We can see that the radiator often can be installed with 120mm fans. Installing a 120mm fan on the radiator is called 120, and so on 240/360/480, etc., which is easier to understand. 

Of course, there are 80, 140 such fan specifications, but the application is less, not the mainstream model. From the number model, we can also see that the larger the size of the fan, the more air, the better the natural heat dissipation. There's nothing wrong with choosing a larger model if it's available.

2. consider the thickness of the radiator.

Generally, there are 22mm/30mm/40mm/60mm, etc., which refers to the cross-sectional thickness of the radiator. The larger the thickness, the larger the cold drainage channel, the more water storage, the larger the connected fin area, and the stronger the heat dissipation capacity. 

However, it should be noted that the thick radiator needs to be matched with a fan with a high speed, such as a fan with a thickness of 60mm. The air volume of a fan with a low speed is not enough, and the heat can not be quickly blown away. This also brings another problem, the fan noise will increase, the use experience will be worse.

In addition to differences in radiator thickness, radiator fin distance also has different designs. The density of fins refers to the spacing between fins, called "FPI". The dense fin, the contact surface with the waterway should be large, the heat dissipation is also good, otherwise weak. In addition, there are single wave and double wave, the heat dissipation capacity of double wave is stronger than single wave. Because the cold exhaust is through the fins to dissipate the heat, fins are conductive materials, heat transfer fast heat dissipation good, if the heat dissipation performance requirements are higher choose dense density of the double wave radiator.

3. the radiator difference of material, copper and aluminum. 

From the material, the heat dissipation capacity of copper is stronger than aluminum. But the channels and fins of the copper radiator need to be welded with tin, tin thermal conductivity is relatively low. The greater the fin density, the more solder joints, which reduces the heat dissipation capacity of the copper radiator, that is, tin welding determines the heat dissipation height of the copper row. 

Aluminum radiators have none of these concerns. 

Therefore, on the whole, the same type of radiator copper and aluminum heat dissipation capacity is very close. Aluminum radiators are widely used in the industrial market because of their low price and good heat dissipation. 

But one of the things that keeps computer water-cooling users from choosing it is the copper-aluminum reaction, which we'll talk about separately. In short, no matter what kind of material, heat dissipation is basically the same, do not have too many concerns.

4. Consider the size and space of the case.

Generally, when we buy the chassis, it will be marked whether it supports the water-cooled radiator and what size it supports. We can choose according to the mark. Of course, some non-standard chassis only show the number of fans supported, which may lead some users to believe that they support the same specifications of cold exhaust, which is actually inaccurate. Because some cases, just in accordance with the size of the fan design of the warehouse, and the actual size of the radiator is to be large. It is necessary to set aside the position of the connection head and the water chamber. In this case, it will mislead some users to choose wrong. If you choose a cold row, please first communicate with the merchant to clearly support the size of the radiator.

The above are some suggestions and precautions for radiator selection for new users of water cooling, I hope to help you.
