Learn to remove the CPU fan from a socket 478 processor.
The socket 478 is a CPU (Central Processing Unit) socket used with Intel's Pentium 4 and Celeron processors. It is called the socket 478 because it has 478 pin holes that interface with the Pentium 4 and Celeron CPU's. Every processor comes with a dedicated cooling fan that helps control the CPU's overall temperature. The cooling fan is instrumental to the life of the CPU chip. If the cooling fan goes bad, the CPU will overheat and cause damage to the motherboard.
Instructions
1. Turn off your computer, disconnect all cables and peripherals from your computers sockets and ports. If you are using a laptop, remove the battery pack from the bottom side of your laptop.
2. Locate your computer's service and maintenance manual. If you don't have access to your computer's service manual, many computer manufacturers provide these manuals from their website's support pages (see Resources).
3. Follow the disassembly procedures outlined in your computer's service manual. Gaining access to your computer's CPU fan may require partial or major disassembly, depending on your computer's make and model. In the case of most laptops, this requires that you remove most of your computer's hardware and outer casing.
4. Locate the cooling fan on your computer's motherboard. Remove the Phillips-head screws securing the fan to the motherboard. Disconnect the cooling fan's power cable from the motherboard and then lift the cooling fan out of your computer.
