The best way to repair an HP computer's CPU cooling fan is by cleaning it.
CPU (Central Processing Unit) chips have a tendency to heat up when used for long periods of time. Keeping the CPU chip at a moderate temperature is essential to the life of your HP computer. If your CPU chip's fan goes bad, or is not cared for, your CPU can overheat and cause irreparable damage to your CPU, motherboard and the surrounding hardware. The most common reason for CPU fan failure is a dirty fan assembly. You can repair your CPU fan by simply cleaning out the fan assembly.
Instructions
1. Turn off the computer and disconnect all cables and devices from the computer. Attach an ESD (Electro-static Discharge) wrist wrap to your wrist. This will prevent damage to your computer's hardware from dormant static electricity. It's a good idea to wait 10 to 20 minutes before you attempt to disassemble your computer.
2. Place the computer on its side and remove the side access panel to reveal the internal components of your HP computer. This process varies for each HP computer model. Refer to your HP computer's disassembly instructions (see Reference 2) for specific instructions on side panel removal.
3. Locate the cooling fan assembly on your HP computer's motherboard. Remove any obstructing hardware devices as directed by your computer's disassembly guide. Disconnect its power cable from the motherboard and remove any Phillips-head screws securing the fan to the motherboard. Lift the fan out of the motherboard.
4. Grasp the fan assembly in one hand and use a compressed air spray can to blow out any large debris from inside the fan assembly.
5. Use a soft cloth or cotton swab to clean out all the dust from inside the fan assembly. Be as thorough as possible and do not apply water or any type of cleaning solution to the fan.
6. Replace the fan and its retaining screws and reconnect the fan power cable to the motherboard. Follow your disassembly guide's instructions to reassemble the computer.
