The fan power supply is plugged into the motherboard. There are usually one or more fan slots for connecting the fan's power cord. The location and number of slots vary depending on the motherboard model and design. Typically, the slots are located near the edge of the motherboard, near the CPU or case fans. The slot is usually marked with "CPU FAN" or "SYS FAN", which corresponds to the connection of the CPU fan and the chassis fan respectively. If you are not sure about the location of the slot, you can refer to the motherboard manual or check the Internet for specific motherboard model and fan slot location information.
Where does the fan power supply plug into the motherboard?
The power supply for the chassis fan just needs to be plugged into the motherboard. With the arrival of summer, the room temperature has increased significantly, and many friends' computers have begun to have blue screens of death due to poor heat dissipation. For computer users, the cooling capacity of the computer can generally be improved by cleaning the dust and installing a cooling fan on the chassis.
1. The chassis cooling fan connector generally has a 3PIN connector and a 4PIN connector, where the 3PIN connector is the fan power connector on the motherboard. If the motherboard has this interface location, just plug the fan power cord into the motherboard. If the case fan only has a 4-pin connector, it can only be powered by the power supply.
2. If your computer case fan also has a 3PIN interface, just connect it directly. Generally speaking, the computer case fan has a built-in 3PIN interface, but it can also be used to connect a large 4PIN jumper. Computer motherboards usually have a SYSFAN interface
Where should the small fan on the motherboard be plugged in?
The fan is installed inside the chassis, with the fan logo facing inside the chassis. Plug the fan cable into the "system fan" pin on the motherboard. The three-pin and four-pin connectors share the same interface. Just make sure to align it with the buckle. Generally, the chassis fans you buy have a built-in 3PIN interface, but they will come with an adapter cable to connect to a larger 4PIN. The computer motherboard has a SYSFAN interface. Generally, two interfaces are 3PIN interfaces. If your chassis fan also has a 3PIN interface, you can connect it directly.
