Would you choose the material distinction?
In addition to buying a boxed CPU, you will face a problem. Which radiator is better? "Which is cheaper to buy" 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 a computer is definitely an aluminum cpu heat sink. The reason why aluminum can be used as a heat sink is that aluminum is not very light and has good thermal conductivity. Therefore, it is widely 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 will be added and cast into aluminum alloy to obtain the appropriate hardness.
Aluminum Heat Sink
Another 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 pure copper radiators are relatively heavy, which can easily bend and deform the motherboard. Products using pure copper radiators are relatively small now.
Is the heat pipe important?
I do n’t know if you noticed that, except for high-end products, boxed CPU coolers are all made of pure aluminum alloy. All standard aluminum alloy), but most brands of radiators with heat pipes?
The heat dissipation effect of the radiator with the heat pipe is far superior to 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 liquid (the principle of thermal expansion and contraction), and then cooperates with the heat sink to conduct heat. The cost of a radiator with a heat pipe is naturally much higher. It starts from 80 yuan to several hundred yuan, and is divided into 2 heat pipes, 3 heat pipes, 4 heat pipes, 5 heat pipes, etc. The more the quantity, the more expensive it is.
However, the custom heat sink extrusion supplier should 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 high-end heat sinks such as 5 heat pipes. A maximum of 3 heat pipe radiators is sufficient.
The bigger the fan, the better?
The design of some CPU radiators is really exaggerated. In addition to the conventional models, many are equipped with 8CM or even 12CM large cooling fans, so that the air volume is greater and the cooling effect is better. However, this fan has high requirements for the installation environment, especially the memory slots designed by some motherboards are too close (or the memory heat sink is too high), or a higher heat sink is installed on the power supply module, which may make it impossible to install. Before buying, be sure to check the installation height of your motherboard. If you really do n’t understand, you can post the motherboard model to the seller to help him judge.
If the super large cooling fan with 8CM ～ 12CM specifications is not a special requirement, don't do it well. Not to mention the difficult installation, the price is still very expensive, why bother yourself?
Down or side blow?
There are many types of CPU cooling fans, but after all, the most basic technical characteristics are inseparable, and the cooling wind direction is one of them. In the early years, the CPU fan of the computer was very simple, that is, the down-press type, which is simply the type that blows the air downwards facing the CPU. Now there is a side blowing method. From the side blowing; the last is the turbine type, this radiator is almost extinct, I will not say much.
In comparison, the two types of CPU heat sinks are more effective and intuitive. For players who want to meet the cooling requirements and plan to build an overall cooling channel, they need to choose side-blow cooling. However, this is also closely related to the air duct in the case. If it is a compact case, when the front and back sides of the case are not intended to install any cooling equipment, passive heatsink is the best choice. In a word, don't blindly think that side blowing is good, and don't think that the push-down type is the most effective.
Is there a difference in silicone grease?
Silicone grease has almost become a part of metaphysics, but the actual test results show that super expensive silicone grease is only a little better than the most common silicone grease. For ordinary players, it is complete, complete, not necessary. However, if you want to focus on DIY actions such as overclocking, a good silicone grease must be carefully considered-it is easy to pass 60 points, and it is difficult to go further after 90 points. The reason is the same.
Finally, if you are an ordinary player, a radiator of about 80 yuan to 100 yuan, a 2 heat pipe to 3 heat pipe radiator is very good, and it is no problem to deal with full load; if it is a small chassis, the CPU often needs to work at full load for a long time. State, the heat sink with about 4 heat pipes is a very good choice. The price is 100 yuan to 300 yuan. Note that the higher the size of the radiator, the higher the brand premium; if you want to overclock toss, DIY players You can consider more advanced radiators, and this part of the editor will not need to say much. In fact, as long as it is not the cheapest miscellaneous brand radiator, the heat dissipation effect will not be too big; for more than 80 yuan of radiators, 99% of the products are better than boxed radiators.
