The fan inside the chassis can be divided into two areas: one is the air inlet; the other is the air outlet. The best way to install a chassis fan is to install 1 or 2 fans in the front or side of the chassis as air inlets, and then install 1-3 fans at the rear of the chassis as air outlets, one in and one out to drive the air inside the chassis. Convection is formed, which will transfer the heat out and achieve good heat dissipation effect. Let's first take a look at the heat source distribution diagram inside the chassis:
Distribution diagram of heat sources inside the chassis
As shown in the picture above, inside the computer case, there are areas such as the CPU area, graphics card area, and hard disk that generate relatively high heat. The red area is the high-temperature area, which is our CPU and power supply area. At the same time, you can see that there are three main air outlets in the chassis: the front chassis fan, the rear chassis fan, and the power supply fan. The chassis fans can only be installed in these positions.
If there is only one cooling fan, then we can only use a single chassis fan installation. If you want to rely on a single fan to draw cold air from outside the case for heat dissipation, it is not suitable to install it behind the case. As shown in the picture above, you can also see that the air flow drawn into the memory only enters the CPU and is sent out by the power fan, so other parts Effective heat dissipation is not achieved, and the overall chassis memory temperature cannot be reduced, so this method is unreasonable. If netizens want to buy a single fan, it is recommended to install it in the front of the chassis in the form of exhaust, or install it in the rear of the chassis in the form of air supply.

How to install it if there are two or more dual case fans? In fact, the dual fans can suck air from the front part of the chassis and then send out the heat of various internal components through the rear and power supply fans, as shown below:

Through the above simple introduction to the principles of air ducts inside fans, I believe everyone already has an understanding of air ducts. Now let’s take a look at the three most common chassis air ducts to see which one is more suitable for you.

Chassis three-dimensional air duct diagram
Chassis vertical air duct diagram
After reading the above three classic schematic diagrams of chassis air ducts, which chassis air duct do you think is better for heat dissipation? Below we attach for you the authoritative evaluation chart from the media:
Comparison of heat dissipation between horizontal air ducts, three-dimensional air ducts and vertical air ducts
Through the comparison of the temperature data above, we can see that the temperature of the vertical air duct is relatively low and is the most expensive among the three types of air ducts. Through the above set of comparative values, we can summarize the following points:
1. Vertical air ducts have good heat dissipation: From the actual effect, the natural heat dissipation effect of vertical air ducts does have an advantage. Since there is only one brand of this kind of chassis, I believe players who are familiar with DIY must understand that the hard drive of this chassis is located on the back panel, so it has a very good heat dissipation effect. Therefore, in addition to the high temperature of the hard disk, the cooling effect of the CPU and GPU is indeed Very good and better than other structural design cases.
2. Three-dimensional air ducts require multiple fans for heat dissipation: From the air duct diagram above, we can see that all five fan positions in the chassis use fans. In this way, a three-dimensional air duct with good heat dissipation can be built. Players need to spend some money. Buy a fan, and the use of multiple fans will make the noise louder. This requires players to choose fans according to their own needs.
3. Practical horizontal air duct: For players who choose horizontal air ducts, their platforms do not generate very high heat, and they do not need good heat dissipation performance. The choice of such an air duct is often determined by the original fans in the chassis. Novice players will use such an economical and practical air duct.
The above is an introduction to the three ways to move the air ducts in the host case. The space inside the case is like a room facing north and south, with ventilation in all seasons without any obstruction. If the air duct design is unreasonable, it may disrupt the air ducts in the case. Let the hardware "heat to death" while still alive.
