Changing the fan is simple – so to speak. First, disassemble the left panel of the case (facing the front of the case), purchase it according to the fan model, then unplug the power supply, remove the fixing bolts to remove the fan, and install a new one.

Hello: 1. The computer host has three fans: the case fan, the power supply fan, and the processor fan. The case fan is best replaced, and the screw can be replaced, and the computer power supply fan needs to be removed from the computer power supply and the shell is opened to replace it.

2. Special attention needs to be paid to replacing the processor fan, and the speed-regulating fan (four wires) of the same specification should be used, otherwise it will rotate at full speed and the noise will be too loud. Then unscrew the fixing screws at the corners of the fan, and you can remove it. Do not disassemble the radiator.

How it works:

Let's start by turning the fan side of the power supply side up and removing the small screws on the four corners (one of which is hidden under the sticker).

Then you can pick up the whole side with the fan and don't push too hard in the process, as it is connected to the power cable.

You can see that the power cord on the fan is plugged into the circuit board (where the screwdriver is pointing) and unplug it.

This is what the frame with the fan looks like when it comes down.

Remove the four big screws that hold the fan on that frame, and the fan is removed.

This is a new fan prepared, the plug of these two fans is not the same, the small head is the same as the original, it can be plugged directly into the circuit board, and the big head can not be plugged directly into the circuit board, but it should be taken out of the iron shell of the power supply, and connected to the D-type four-pin plug of the power supply.

After the fan is wired, put the convex side of the fan blade in the original frame, and then put the protective iron mesh on the frame, align the screw holes (pay attention to the reverse front when placing the iron mesh, and the convex side is outward), and put on the screws.

Finally, buckle the fan frame and the power base frame together, put on the screws, and complete the whole fan replacement process.
