Cooling fan is an indispensable part of the computer equipment, its advantages and disadvantages will directly affect the computer's operating efficiency and service life. Therefore, how to determine the merits of the cooling fan has become the user must consider when choosing a cooling fan. The following are some of the methods and techniques that will be provided in this article to determine the advantages and disadvantages of cooling fans:  

  1. Rotation speed and airflow rate: Cooling fans help remove heat generated by processors, graphics cards and other hardware by increasing the speed of air flow. According to LU Master software testing, the higher the fan's RPM and the faster the airflow speed, the better the cooling effect. Therefore, when choosing a cooling fan, you should select a product with a higher rotational speed.

  2. Noise: Cooling fans produce a certain amount of noise when running, but if the noise is too loud, it will affect the user's experience. Therefore, when choosing a cooling fan, you should choose a product with less noise.

  3. Heatsink material: the heatsink is an important part of the cooling fan, its material will affect the cooling effect. At present, the material of the heatsink is mainly copper, aluminum, iron and so on. Among them, copper heatsink has the best heat dissipation effect, but the price is high; aluminum heatsink has the second best heat dissipation effect, but the price is relatively low; iron heatsink has the worst heat dissipation effect, but the price is the lowest.

  4. Fan blade shape: the shape of the fan blade will affect the airflow rate and cooling effect. Generally speaking, the more complicated the shape of the fan blade, the faster the airflow speed and the better the heat dissipation effect.

  5. Fan bearing type: the type of fan bearing will affect the life and noise of the cooling fan. At present, the main types of cooling fan bearings are ball bearings and oil bearings. Among them, the advantages of ball bearings are high efficiency, low heat and low noise, and the advantages of oil bearing are low price, small size, but late noise and easy to wear.

  6. Brand and after-sales service: choosing a cooling fan of a well-known brand can guarantee the quality of the product and after-sales service. At the same time, you can also understand the advantages and disadvantages of the product by checking the product's user reviews and word of mouth.

  In short, judging the advantages and disadvantages of a cooling fan requires comprehensive consideration of a number of factors, including rotational speed and airflow speed, noise, heat sink material, fan blade shape, fan bearing type and brand and after-sales service. When choosing a cooling fan, you should choose a product that suits your needs and budget.
