This is the original! CPU radiator you will pick it?

On Tuesday, Xiao Bian saw that there was a small friend who left the message to configure and asked Xiao Bian. In general, there is no problem with looking at it, but if you look at it carefully, it is not right. The partner bought a bulk CPU but did not choose a heat sink. How can this be used? It was only after I asked that this little friend did not take into account the radiator. Well, today happens to take this issue, Xiao Bian to everyone to push the radiator to buy knowledge.

Material selection will you choose?

In addition to buying a boxed CPU, you will face a problem. Which one to buy a radiator? Which one is cheaper to buy or which one is better to buy? This should be based on the most basic "use of materials" of the CPU.

In general, the most economical cooling fan for computers is definitely aluminum alloy radiators. The reason why aluminum can be used as a heat sink is because aluminum has a light weight and a good thermal conductivity. Therefore, it is generally used as the best material for heat dissipation of electronic parts. However, the heat sink is not 100% pure aluminum, because pure aluminum is too soft, so it will add a small amount of other metals, cast into aluminum alloy to obtain the appropriate hardness.

Another material is copper. Copper has better thermal conductivity than aluminum, but its cost is much higher than that of aluminum heat sinks. Considering the cost, pure copper radiators are generally used for high-end heat sinks and the cost is relatively high. Another point is that pure copper heat sinks are relatively heavy and can easily bend and deform the motherboard. Nowadays, relatively few products use pure copper heat sinks.

Is heat pipe important?

Do not know if you noticed no, generally boxed CPU cooler in addition to high-end goods, are pure aluminum alloy texture (previously aluminum + copper design, but in recent years the CPU's thermal power is low, almost all Standard all-aluminum alloy), but the radiators of various brands are mostly equipped with heat pipes?

Radiator heat pipe with heat pipe effect is far more than ordinary products, this is because the copper heat pipe contains liquid heat transfer liquid, through the liquid flow (the principle of thermal expansion and contraction) quickly take away heat, and then with the heat sink heat transfer. The cost of radiators with heat pipes is naturally much higher. Starting from 80 yuan to several hundred yuan, it is divided into 2 heat pipes, 3 heat pipes, 4 heat pipes, 5 heat pipes and so on. The more the price, the more expensive.

However, Xiao Bian wants to remind everyone that if you are not an overclocked player, or the CPU's thermal power design is not particularly high, there is no need to buy a high-end heat sink like 5 heat pipes, and a maximum of 3 heat pipe heat sinks will suffice.

The bigger the fan, the better?

Some CPU heatsink designs are 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 larger and the cooling effect is better. However, this type of fan has a high requirement for the installation environment, especially if the memory slots of some motherboard designs are too close (or the memory heat sink is too high), or if a higher heat sink is installed on the power supply module, it may not be installed. Before buying, be sure to check the installation height of your motherboard. If you do not understand it, you can paste the motherboard model to the seller to help him judge.

On Xiao Bian's point of view, 8CM ~ 12CM size of the large cooling fan if not special needs or not as well, do not say that the installation difficulties, the price is still very expensive, why give yourself trouble?

Under pressure or side blowing?

There are many types of CPU cooling fan, but in the end it can not be separated from the most basic technical features, one of which is the cooling wind direction. In early years, the computer's CPU fan is very simple, that is, under the pressure type, simply that is facing the CPU down the kind of hair; now there is a more side blow mode, the fan is designed on the side of the CPU heat sink, From the side to the hair; the last is the turbine, this radiator has almost disappeared, Xiao Bian will not say more.

Comparing the heat dissipation methods of the two CPU heat sinks, the push-down type is more effective and intuitive; and for the players who want to meet the heat dissipation requirements and intend to build an overall heat dissipation channel, the side-blown heat dissipation is selected. However, this is also closely related to the air duct in the chassis. If it is a compact chassis, the front and rear sides of the chassis do not plan to install any cooling devices. The push-down heat sink is the best choice. In a word, don't blindly think that side blowing is good, and don't think that pressing down has the most effect.

Is there a difference in grease?

Silicone grease has become almost a part of the metaphysics, but the actual test results show that the ultra-expensive silicone grease is only a little better than the most common silicone grease, and for the average player, the end. Full. No. Must! However, if you want to focus on such DIY actions as overclocking, a good silicone grease must be carefully considered - it is easy to pass 60 points, and it is difficult to think about it after 90 minutes. The reason is the same.

To conclude, if it is an ordinary player, a radiator of 80 yuan to 100 yuan, 2 heat pipes to 3 heat pipes is very good, and it is no problem to handle full load; if it is a small chassis, CPUs often have to work full time for a long time. State, 4 heat pipe around the radiator is a very good choice, the price Well, 100 yuan to 300 yuan have, pay attention, the higher the size of the radiator, the brand premium is higher; if you want to overclock toss, DIY players Can consider more advanced radiators, this part of Xiao Bian need not say more. In fact, as long as it is not the cheapest kind of radiator, the cooling effect will not be too big; over 80 yuan radiator, 99% of the products are better than the boxed radiator cooling effect. Of course, if you are a fan of AMD's belief lamp radiator, Xiao Bian did not say anything...
