For many installed users, the graphics card heat sink comes with it, so users have no choice. For the CPU cooler, you can choose freely. Next, let's talk about the misunderstanding of the CPU radiator.
CPU cooler selection error 1: the bigger the fan, the better?
Different radiators have different sizes of fans, and the diversified products provide users with more choices. The large-sized fans are not only visually more impactful, but also the large-size fans can drive more people's impressions. Large airflow, which is why many friends favor big fans.
The size of the fan does directly affect the air volume, thus providing different heat dissipation effects, but the air volume is not determined solely by the size of the fan. The number of blades of the fan, the shape design of the blade and the thickness also cause different air volume. The influence of these parameters may be Will exceed the effect of fan size on air volume.
CPU cooler selection error 2: tower cooling is better than blowing?
For tower cooling and lower blowing cooling, it is believed that most users choose tower cooling, because in general, the larger the radiator has a larger surface area, the heat dissipation effect is also improved. Tower-shape heat sink usually have a larger volume, and the middle transparent design allows the air to circulate better. In addition, the tower radiator is often more expensive, so many people think that the tower radiator is lower than the bottom. The radiator is good.
However, for most users, the down-drain cooler is actually enough. In addition, the lower blower heat sink has an advantage in that the airflow direction of the fan does not flow directly from the front to the rear, but flows from the center to the surroundings, so that the components around the CPU can be provided with auxiliary heat dissipation. The platform used for time is also a good thing.

CPU cooler selection error 3: Is the heat sink installed as tight as possible?
Many users always think that the heat sink should be as tight as possible when installing the heat sink. The screws are screwed very tightly. This is actually wrong, because the heat sink and the CPU can be pressed tightly to reduce the thermal grease. The thermal resistance between the two provides better heat dissipation performance, but the tightness of the installation is also limited. If this limit is exceeded, the hardware will mainly be damaged.
Therefore, under normal circumstances, the snap-on heat sink can be fastened. The aluminium CPU heat sink fastened with screws can have a large resistance when the screw is tightened. After the installation, the heat sink will not shake or rotate, and the main board is not deformed. It is also a basis for judging the reasonable installation of the radiator.
CPU cooler selection error 4: mirror base must be good?
The heat sink must be in contact with the surface of the CPU to transfer heat, and the heat conduction effect of the contact surface directly affects the heat dissipation performance of the heat sink. So we just said that the choice of silicone grease and the amount of silicone grease is a science. In addition to silicone grease, the radiator base is also a consideration. The most important are material and process issues. Radiator products with superior materials and craftsmanship can have excellent heat dissipation.
CPU cooler selection error 5: Water cooling is respectful, air cooling is low?
In terms of heat dissipation, the cooling capacity of water cooling heatsink is much larger than that of conventional air-cooled radiators, because the water flow inside the water is much faster than the air-cooled radiator that uses heat pipes to conduct heat. However, in the past, water-cooling and heat-dissipating installations were difficult and costly, and it was difficult to enter the homes of the people. Peripheral manufacturers have developed an integrated water cooling in order to popularize water cooling.
