Basic instructions on how to properly remove and install a CPU cooling fan

The cooling fan is a very important component in your laptop. It helps keep the CPU temperature stable. However, for the cooling fan to work best, it is necessary to have good maintenance and cleaning methods for the cooling fan. Let's learn how to remove and install the CPU cooling fan most effectively.

How to remove CPU heatsink fan

Unplug the fan control wire from the socket on the Mainboard labeled CPU_FAN.

Turn the fan locking pins counterclockwise. Pull the two locking pins diagonally out of the holes on the motherboard at the same time to ensure they do not move out of place.

Perform the same pulling motion with the remaining two locking pins.

Check if the locking pins have been pulled out of the holes on the motherboard, then you can lift the fan out and ask the motherboard.

In some cases, the fan may be stuck to the back of the CPU and cannot be removed, the cause may be the heatsink.

Now gently rotate the fan to separate this layer of heat sink so that the heat sink can be removed more easily.

After removing the heatsink fan from the CPU , you need to turn the locking pins clockwise to restore the locking pins to their original position. This is to make it easier to reinstall the fan later.

After removing the heatsink fan from the motherboard, it needs to be cleaned thoroughly and the heatsink layer on the fan surface needs to be cleaned so that the heatsink fan does not stick to the CPU anymore.

Place the fan's heatsink surface against the back of the CPU, making sure that the fan's locking pins are properly aligned with the holes on the motherboard.

Press the 2 diagonal locking pins down into the holes on the Mainboard at the same time to make sure they do not move. Do the same with the remaining 2 locking pins of the heatsink fan.

After the cooling fan has been fixed to the Mainboard, you need to plug the fan control wire into the socket on the Mainboard marked CPU_FAN.

Based on the radiator fan

Determine the direction of the fan's wind through the shape of the fan blades: The part of the fan blade that curves away is the air intake side. The direction of the fan blade support bars with the fan frame, along with the information label, is the wind direction only.

When installing a cooling fan for the case, you need to pay attention to the following steps to effectively cool the machine:

Step 1: Determine the heat dissipation flow for the case
Step 2: Determine the range for pressure balance in the case
Step 3: Clean up computer parts and components to avoid obstructing the air flow in the machine.
Step 4: Install the fan according to the instructions above.

Some notes when assembling CPU cooling fan

Be sure to rotate the fan so that the fan control wire is in a convenient position to connect to the socket on the motherboard.

The locking pins must be properly aligned before installing the fan.

Be careful when installing the locking pins into the holes on the motherboard because they are quite easy to bend with the white plastic material.

After installing the heatsink fan, you should flip the back of the motherboard to check the position of the locking pins to see if they are correct and tight.

Installing the CPU cooling fan onto the Mainboard requires precise technical care because if the assembly is not correct, the contact surface of the cooling fan with the CPU will not be suitable, which can easily cause problems such as freezing, lagging, etc. when the machine is overloaded with heat.

Above are basic instructions on how to disassemble the CPU cooling fan that you need to know to be able to clean the cooling fan at home in the simplest and most convenient way.
