Advantages of tower heatsink
Many users prefer the tower radiator when choosing the processor radiator, but we know that there is another kind of radiator, the down pressure radiator. However, unless it is a small chassis, no one basically chooses this, so why not choose the down pressure radiator? Is the cooling effect of tower radiator better than that of down pressure radiator?
About CPU Heatsink :
The CPU heatsink transfers heat to the fins of the heatsink through silicone grease, copper pipe, base and other heat conducting media, and then uses a fan to blow away the heat. From the working principle, what can affect the heat dissipation effect is the heat conduction effect of the heat conduction medium and the size and speed of the fan.
Therefore, a good radiator must have a smooth base, heat pipe with strong thermal conductivity, a good fin design (contact process, quantity, area, etc.) and a fan with fast and large speed. But whether it is tower radiator or down pressure radiator, this kind of radiator can be made, but why do we prefer tower heatsink?
Comparing the thickness of the two heatsinks, we can see that the tower heatsink is basically about three times that of the down pressure radiator, that is, the area of the cooling fins of the tower radiator is about six times that of the down pressure radiator when the number is the same.
On the base, whether tower type or down pressure type, the heat pipe area is basically the same, which means there is no difference in heat conduction efficiency from the CPU to the base, and the biggest difference between tower radiator and down pressure radiator is the total area of cooling fins. The larger the area of the cooling fins, the better the cooling effect will be. Only from the contact between the CPU and the base, the heat conduction efficiency is almost the same. However, because the tower heatsink has a large area of cooling fins, it can dissipate the heat faster, thus indirectly improving the heat conduction efficiency between the CPU and the base.
The wind direction of the tower heatsink is different from that of the down pressure heatsink. The tower heatsink blows on the side, while the down pressure heatsink blows directly on the CPU. Although the heat generation of the CPU is very large, the CPU is not the only heat source of the main board. For example, the heat generation of the power supply module of the CPU is not small, and there are memory modules. Because the tower radiator blows on the side, it can only drive the air circulation, It can not solve the problem of heat dissipation except for the CPU, but the down pressure type also indirectly provides heat dissipation conditions for other components such as the motherboard because it directly blows the CPU.
Large chassis and high-end motherboards generally do not use down pressure heatsinks, because high-end motherboards will be equipped with cooling modules for components that need cooling, so tower radiators are the best choice, and only need to heat the CPU. The motherboard without good heat dissipation design, medium and low-end processors and small chassis can choose the down pressure heatsink .
