Where is the CPU fan connected to the chassis power cable, and where is the CPU fan power connector?

One is three grounding wires, one of the four is a speed regulating line, and one is grounded. There are also two positive and negative poles, red positive, black negative, you and the fan get it, then turn it on, plug it in, don't worry, it won't burn, if you can't turn it, just plug it in the other way around, and that's it.

The black is the ground wire, the red is 5V, the yellow wire is 12V, the four-heel you only need to connect the black and yellow, and the three-heel is black and red.

The CPU fan connector on the motherboard is generally near the CPU socket, and the word "CPU fan" printed on the circuit board of the motherboard is the power connector of the fan. Here is a screenshot of the motherboard, where it is marked.

Connect the motherboard well. The motherboard has a BIOS, which detects the speed of the fan and is more conducive to controlling the temperature in the case.

1. There are generally CPU cooler fan connectors, graphics card radiator fan connectors and case fan connectors on the motherboard, all of which can be detected by the BIOS in order to adjust the temperature in the case.

2. If it is connected to the power supply, it will keep rotating, and the computer motherboard is equal to the deaf and blind, and it is impossible to command the speed of the fan. On the one hand, it is not conducive to regulating the temperature of the chassis, and on the other hand, it is not conducive to energy saving.

3. The interface in the chassis and the output voltage are also filtered, which is more stable.

If the fan is 4-pin, connect the 4-pin connector on the motherboard to automatically adjust the speed.

More silent. If it's a 3-pin or 2-pin fan, it doesn't matter if it's connected.

The CPU fan connector on the motherboard is generally near the CPU socket, and the word "CPU fan" printed on the circuit board of the motherboard is the power connector of the fan. Here is a screenshot of the width of the motherboard shed, and the location has been marked in the picture.

Since the heat generated by the CPU when working is conducted to the heat sink, and then the heat of the heat sink is blown away by the cold air brought by the fan, and the amount of heat that the fan can conduct is related to the area of the heat sink, generally speaking, the larger the contact area between the heat sink and the air, the better the heat dissipation effect of the fan.

But there is a certain premise for this statement, and that is if there is enough remaining space in the chassis. If the case of the computer is not large in terms of heat dissipation space, if there is not enough remaining space, it is difficult to install a large heat sink into the case, even if it can barely be installed in the case, too large a contact area will block the hot air around the heat sink from dissipating quickly, resulting in the overall temperature inside the case is too high, so as to affect the operation performance of the entire computer, so it is recommended that the size of the heat sink area should be matched with the case, and the large area of the heat sink cannot be pursued by one.

The fan line insertion method of the machine banquet is as follows: HonorTool Material: Dell K550 main chassis, fan.

1. First, place the fan in the corresponding installation position of the main chassis.

2. Then use a screwdriver to fix the fan on the back of the main chassis.

3. After that, sort out the power cable of the fan. Hui Hui.

4. Then plug the power cable of the fan into the corresponding slot of the main chassis.

5. Finally, the fan rotates successfully.
