A cooling fan is a device that converts electrical energy into air kinetic energy. Its main function is to dissipate heat from mechanical 

products. Many products, such as computer hosts, are equipped with cooling fans. However, many devices have insufficient heat

 dissipation capabilities (or generate heat energy too quickly), resulting in the inability to dissipate heat in a timely manner. This

 situation can cause high heat energy to be generated inside the product during continuous use, which can directly damage the

 internal components of the product. Cooling devices must be used for heat dissipation. Laptops are equipped with cooling fans

 (small), and the external heat sink of the laptop is a type of cooling fan. So what are the precautions to take when using a laptop fan?

Firstly, do not block the air outlet and do not place the laptop on a blanket or fabric. This can easily block the air outlet and cause 

dust to accumulate. If the location is unstable or damp, you can purchase a laptop fan base online to help dissipate heat from the 

bottom of the laptop, enhance its cooling capacity, and make it more convenient to place.

Secondly, the usage environment: The surrounding air must be well ventilated and the space should be large enough. During the 

operation of the laptop, especially when downloading and playing large games, the internal CPU runs faster and the temperature

 will also increase, causing the computer to heat up. However, the internal space itself is small. If the laptop is placed in a space 

with limited air circulation, even if the internal fan can dissipate the heat, the external temperature cannot be lowered, which will

 result in the cooling fan not being able to dissipate the heat and causing CPU damage.

Thirdly, it is important to avoid moving the laptop after it is turned on. When the laptop is running, its internal components will 

also run accordingly. If the laptop is moved from time to time, it will not only cause significant damage to the internal hard drive, 

but also result in uneven and unbalanced rotation of the laptop fan. Over time, this will cause the center of gravity to shift and

 lead to damage.

Fourth, regular cleaning and refueling: No matter how good the parts are, they cannot withstand the wear and tear of time. 

Regular maintenance is also important for fans. Adding some oil and cleaning dust appropriately can extend the life of the fan.
