How to replace the CPU in the computer? What should I pay attention to?

Different models of CPU have different pins, so to upgrade the CPU, we must first inquire about the CPU models supported by the motherboard and whether to upgrade the BIOS. Understand the interface of CPU, and check the CPU with software, mainly depending on the interface and power consumption. The replaced CPU must meet the power consumption and interface.

Tools for replacing cpu: liquid silicone, screwdriver, brush, rag or toilet paper.

The replacement steps are as follows:

1. As shown in the figure, disassemble the computer mainframe case and remove the cooling fan on the CPU.

2. Clean the dust of the CPU fan. You can brush the dust with a brush and then blow it with a hair dryer, as shown in the figure.

3. Remove the CPU from the CPU bracket with a screwdriver. Note that the CPU has four concave points, which should correspond to the CPU bracket and then mount the bayonet, as shown in the figure.

4, CPU needs to use liquid silicone to help heat dissipation, so when buying CPU, you can ask the seller to send a small bag.

5. Wipe the old silicone grease with clean toilet paper or rag. If the silicone grease is cured, just gently buckle it with your hand.

6. Then smear new silica gel on the CPU surface, smear the piece with silica gel, and gently smooth the silicone grease. Remember not to have too much silicone grease, just a thin layer.

7. Then install cooling modules such as fans, close the back cover of the chassis, and then start the self-inspection. Restart the computer and check again to make sure there is nothing unusual.
