Is it possible to install a desktop computer without a case fan? What impact does it have on computer performance? PHP editor Youzi will give you a detailed answer: This article will delve into the importance of chassis fans to desktop computer performance and analyze the advantages and disadvantages of different cooling solutions. Read on to learn whether your system requires a case fan and the potential risks you may encounter without one.

#Can a desktop computer not be equipped with a case fan?

Yes, but this needs to consider several issues, one is the heating power of the internal hardware, the other is the heat dissipation efficiency of the chassis itself, and the other is the ambient temperature. First of all, we need to understand that heat will be transferred only if there is a temperature difference. That is to say, if the temperature of the graphics card and CPU is higher than the air temperature inside the chassis, and the temperature inside the chassis is higher than the external ambient temperature, the heat will be dissipated outward.

In winter, because the ambient temperature is low and the heat dissipation efficiency of the chassis is high, the internal temperature of the chassis will generally be stable within a reasonable range. To give a loose example, assuming that the ambient temperature is 15°C and the air temperature difference inside the chassis is maintained at 30°C to achieve heat dissipation balance, then the internal temperature is 45°C. The greater the heating power of the internal hardware, the higher the temperature difference required to achieve heat dissipation balance, and the higher the internal temperature of the chassis.

In summer, the ambient temperature is high. Assume that the temperature difference still needs to be maintained at 30°C to achieve heat dissipation balance. Assuming the ambient temperature is 35°C, then the air temperature inside the chassis becomes 65°C. If it is specifically implemented in the graphics card and CPU The temperature will far exceed 65℃, and it will be in a high temperature working state. In this case, if it is a high-power graphics card and CPU, the temperature will be higher.

So, the conclusion is: computers with high heating power need to install chassis fans in both winter and summer. Computers with medium heating power do not need to install a case fan in winter, but they do need it in summer. Computers with low heating power do not need to install a case fan in winter or summer.

Of course, the actual situation is more complicated. The heating power of the computer changes with the workload of the hardware. The volume, material, and structure of different chassis have an impact on the heat dissipation capacity, as well as the heat dissipation capacity of the CPU and graphics card. The heat dissipation efficiency of the radiator will also affect the final effect. If the heat dissipation efficiency of the radiator is high, then the ambient temperature inside the chassis can be slightly higher and it can work stably, and there may be no need to install a chassis fan.
