It turned out to be like this! Will you pick a CPU cooler?

          Would you choose the material distinction?  

          In addition to buying a boxed CPU, everyone will face a problem.Which radiator is better to buy? "Which is cheaper to buy which" or "which is better to buy which"? This depends on the most basic "materials" of the CPU.  

         Generally speaking, the most economical cooling fan for computers is definitely the radiator made of aluminum alloy. The reason why aluminum can be used as a heat sink is that aluminum is not rich in weight and has good thermal conductivity. Therefore, it is generally used as the best material for heat dissipation of electronic parts. But the heat sink is not 100% pure aluminum, because pure aluminum is too soft, so a small amount of other metals are added and cast into aluminum alloy to obtain the appropriate hardness. 

         The other material is copper. Copper has better thermal conductivity than aluminum, but the cost is much higher than aluminum heat sinks. Considering the cost, pure copper radiators are generally used for high-end radiators, and the cost is relatively high. Another point is that the pure copper radiator is heavier, and it is easy to bend and deform the motherboard. There are relatively few products using pure copper radiator. 

         Is heat pipe important?  

         I don’t know if you have noticed it. Except for high-end products, the general boxed CPU coolers are made of pure aluminum alloy (previously there was aluminum + copper design, but the thermal power consumption of CPUs has been low in recent years, almost all of them The standard is all aluminum alloy), but most of the radiators of various brands have heat pipes?  

         The heat dissipation effect of a radiator with a heat pipe is far better than that of ordinary products. This is because the copper heat pipe contains a fluid heat-conducting liquid, which quickly removes heat through the flow of the liquid (the principle of thermal expansion and contraction), and then cooperates with the heat sink to conduct heat. The cost of radiators with heat pipes is naturally much higher, starting from 80 yuan to several hundred yuan, and they are divided into 2 heat pipes, 3 heat pipes, 4 heat pipes, 5 heat pipes, etc. The more the quantity, the more expensive the price.  

         However, I would like to remind everyone that if you are not an overclocker or the thermal power design of the CPU is not particularly high, there is no need to buy a high-end radiator like 5 heat pipes. A maximum of 3 heat pipe radiators is enough.  

         The bigger the fan, the better?  

         The design of some CPU coolers is really exaggerated. In addition to the conventional models, many are equipped with 8CM or even 12CM super cooling fans, so that the air volume is larger and the heat dissipation effect is better. However, this kind of fan has high requirements for the installation environment, especially if the memory slot of some motherboards is too close (or the memory heat sink is too high), or a higher heat sink is installed on the power supply module, it may be impossible to install , Be sure to understand the installation height of your motherboard before buying. If you really don’t understand, you can post the motherboard model to the seller to help him judge.

         Press down or side blow?  

         There are many types of CPU cooling fans, but they are inseparable from the most basic technical features, and the cooling wind direction is one of them. In the early days, the CPU fan of the computer was very simple, it was a down-pressure type, in short, it was the kind of blowing downwards directly facing the CPU; now there is also a side blowing method, the fan is designed on the side of the CPU radiator. Blowing from the side; the last is the turbo type, this kind of radiator has almost disappeared, I won't say much.

          Comparing the heat dissipation methods of these two CPU radiators, the down-pressure type is more effective and intuitive; for players who want to meet the heat dissipation requirements and plan to build an overall heat dissipation channel, they should choose side-blowing heat dissipation. However, this is also closely related to the air duct in the case-if it is a compact case, when no heat dissipation equipment is planned to be installed on the front and rear sides of the case, the down-pressure radiator is the best choice. It's just one sentence, don't blindly think that side blowing is good, and don't think that the downward pressure is the most effective.
