Abstract: For notebook users, the simplest way to cool down is to clean the fan. The time for fan cleaning depends on the usage environment. It is calculated according to the normal cleaning time of the notebook, at least once every six months. If you clearly feel the palm rest temperature If the temperature rises significantly, or the fan often accelerates and makes abnormal noises, you should first clean the laptop fan to solve the problem of excessive temperature.
【Laptop Fan Cleaning】Laptop Fan Cleaning Tutorial Detailed Fan Cleaning and Cooling Scheme
1. Remove static electricity and wear rubber finger gloves
This step can be collectively referred to as I have already made it very clear about the protection work before disassembling and assembling the laptop. It is mainly to prevent static electricity breakdown. Netizens can use rubber gloves or insulating gloves instead.

2. Remove the notebook protective back cover and remove the battery
The back cover of the notebook plays a protective role and is the heart of the entire notebook protection. Because it protects the most important CPU and GPU of the notebook, you must be extra careful when disassembling it and do not use excessive force. To avoid damage to the protective plate. Special attention should be paid to the fact that the protective plate material of some notebooks is very thin. Do not use brute force to remove such protective plates. The battery must be removed before disassembling the notebook to avoid damage when touching the chip.

3. Remove the notebook CPU and GPU heat dissipation When you disassemble the protective back cover of the notebook, you will see the CPU and GPU. These two chips are the heart of the notebook and are the core components that provide us with performance and graphics display, so treat them more carefully. Be careful and don’t be impatient. The internal design of each series of notebooks is unique.They are different, so there may be slight differences, so be sure to observe them carefully before disassembling them.

4. Disassemble notebook fan
Generally speaking, notebooks with independent graphics cards will have two tubes. Copper is used to help the CPU and GPU dissipate heat. These two copper tubes are very important. When disassembling the fan, be sure to apply force on the bottom of the two copper tubes, otherwise they may deform and break.

5. Clean the laptop fan
The laptop fan is the focus of this cleaning. The author’s laptop has been kept in the office so there is not a lot of dust, but dust is a killer for laptop accessories.

6. Apply silicone grease
The role of silicone grease is to fill the gap between the heat dissipation device and the notebook chip to achieve the best heat dissipation effect, so be sure to pay attention to the smoothness when applying. The more silicone grease you apply, the better. Just a smooth layer is enough. Since silicone grease contains silver, be sure not to get silicone grease onto the laptop circuit board.

Clean the entire laptop fanThe process is relatively simple and does not have any technical difficulties. However, netizens who are cleaning the fan for the first time will be very nervous. This is a normal process. There are also many places that need to be paid attention to during cleaning, such as the CPU and GPU chips. These parts Any damage will cause the notebook to be unable to be opened.
