How to Install CPU Fans

Every CPU (central processing unit) must have its own dedicated cooling system. If not, the CPU will overheat and may cause severe damage to the motherboard and the hardware surrounding the CPU chip. Additionally, without a proper cooling system, the CPU may end up frying itself. All CPU cooling systems come with a dedicated cooling fan that runs when the CPU gets too hot. But just like any piece of computer hardware, the cpu cooling fan goes bad from time to time. Fortunately, many computer's have a built-in alert system that notifies the user when the cooling system is not working properly.

Instructions

1.Obtain your computer's service or maintenance manual. If you don't have ready access to your computer's service manual, many computer manufacturer's post service manuals for most of their computers from their website for free.

2.Follow the step-by-step disassembly instructions outlined in your computer's service manual. You need to strip your computer down to the motherboard to gain access to the CPU chip. If you are using a desktop computer, there should be minimal disassembly required. However, gaining access to your laptop's CPU chip is a little trickier. You will have to remove much of your computer's hardware including your hard drive, RAM, modem, wireless card, keyboard and possibly your DVD drive. Additionally, you may have to remove the LCD panel, and completely disassemble your laptop's outer casing.

3.Locate your CPU cooling fan on your motherboard. Disconnect the laptop cooling fan's power cable from the motherboard, and then remove the Phillips screws securing the cooling fan to the motherboard. Lift the cooling fan out of the motherboard assembly and set it aside. This will reveal the surface of your CPU chip.

4.Use a clean paper towel, or cloth to apply a thin coat of thermal grease to the surface of your CPU chip. This prevents your CPU from heating up to quickly and frying once you power on your computer.

5.Place the new cooling fan over the CPU chip. Align the screws on the laptop CPU fan with the screw holes on the CPU chip assembly. Replace the retaining screws, and then attach the cooling fan's power cable to the motherboard.

6.Follow the instructions detailed in your service manual to reassemble your computer.
