Where does my cpu fan connector connect to the motherboard?

Where is the CPU fan connector plugged in? This is a common question, especially for first-time computer users. This problem is closely related to the installation position of the CPU fan, which directly affects the cooling effect of the computer. PHP editor Yuzai will answer this question in detail and help you connect the CPU fan correctly to ensure the stable operation of the computer.

Where is my cpu fan connector connected to the motherboard?

The interfaces on the motherboard that can be connected to fans include CPU_FAN, SYS_FAN, CPU_OPT, aio_pump, chip_fan, PWR_FAN, etc. CPU FAN is the power interface for the processor radiator fan. It is generally located on the left and right sides of the CPU and needs to correspond to the 4PIN cable connected to the processor radiator. Generally, this interface is dedicated to radiator fans, and other radiator fans can be connected to other 3PIN or 4PIN interfaces on the motherboard.

Is the computer case fan plugged into the motherboard or is it directly connected to the power supply?

The chassis fan power cable can be connected to the motherboard or the power supply.

1. The chassis fan is connected to the motherboard. You need this small 4PIN fan. Connect it to the pin marked SYS_FAN on the motherboard:

2. The chassis fan is connected to the power supply. You need this A fan with a large 4PIN, connected to the large 4PIN output plug of the power supply:

Which interface on the motherboard is the chassis fan usually plugged into?

1. If you want to plug the chassis fan into the power supply, you only need to connect it to the large 4PIN output plug of the power supply. In addition, the chassis fan can also be connected to the motherboard. Just connect the power supply Just connect the wire to the pin marked SYS_FAN on the motherboard.

2. Since the motherboard has many cooling fan interfaces, there are 3PIN interfaces and large 4PIN interfaces (D-type interfaces) which are very common. Generally speaking, the chassis fans with 3PIN interfaces are connected to the motherboard, and the D-type interface All fans are connected to the parallel power supply interface of the power supply. In the case of multiple fans, they support series connection. Some chassis fans are very user-friendly and will be equipped with both 3PIN and D-type ports to meet interface compatibility.

3. If it is a large 4PIN, you can connect it to the power supply, because the 3PIN on the motherboard may not be connected, but if it is completely connected to the 4PIN interface of the power supply, the fan speed will not be adjustable. When it is fully operational, it is recommended to purchase a fan speed regulator for coordinated use, but now there are also fans with speed regulation available for purchase.

Where does the air outlet of the host fan face?

The installation direction of the chassis fan is with the air inlet facing inward and the air outlet facing outward. The main function of the box fan is to assist in heat dissipation. The fan is used to arrange the internal air duct of the computer host to quickly suck in external cold air and quickly discharge the heat inside the host, effectively reducing the temperature. In fact, the simplest and most practical way to know which side of the chassis fan is the air inlet and which side is the air outlet is to energize the fan and feel it with your hands.

For example, we are going to install a chassis fan at the fan position near the CPU at the back of the chassis. This fan position undoubtedly needs air to discharge the heat inside the chassis. First, we pick up the chassis fan. The back of the chassis fan is for the air outlet. Install it from inside the chassis and align it with the four holes on the chassis fan.

　

So I asked where exactly the fan should go to the motherboard?

You need to take a photo of the fan plug.

1. Generally, the power supply fan has a three-pin plug, and the three-pin plug can be directly plugged into the three-pin socket on the motherboard.

2. Some fans do not have plugs, so you can only modify a plug yourself. It can be changed to 4PIN or three-pin, depending on what parts you have.

How many ways are there to fix the CPU cooling fan on the motherboard?

Get ready for the CPU fan. Below I take the Intel LGA 1366/115X/775 structure CPU installation fan as an example.

Align the four ends of the fan into the four CPU fan fixing holes on the motherboard.

、

Then push down the CPU fan feet. Pull it out to see if it can be easily pulled out. If it means it is not stuck, check again.

Note: Do not press without aligning the fixing holes, otherwise the CPU fan legs will be crushed.

After the CPU fan pins are completely inserted into the motherboard fixing holes, press down the four pin clips on the fan.

Note: Press the clip diagonally.

After all the fan fixing clips are pressed down, check to see if the four legs of the fan are fully attached to the motherboard.

Finally, connect the CPU fan power supply.

Note: There are several fan power connectors on the motherboard, and they must be connected to the connector marked: CFNA or CPU_FAN.
