Step 1: Appearance. Must be exquisite. If a cooling fan product does not even have a beautiful appearance, it is definitely not a good product. The precision of the cooling fan mold used is definitely not high. Although a beautiful appearance does not mean perfect quality, a fan with perfect quality must have a beautiful appearance. Therefore, when choosing a fan, you may want to touch the surface of the fan with your own hands to see if it sticks, if the color is uniform, if there are any defects in the welding joints, and then rotate the fan blades by hand to see if the balance is perfect and if there are any abnormal noises.

Step 2: Noise. The level of noise determines the performance of a product. If a fan product produces a lot of noise, it is clearly a defective product. The better the quality of the fan, the more efficient the design and the lower the noise.

Step 3: Brand. Of course, branded products should always be superior to those of such miscellaneous brands. Choosing a manufacturer with high brand awareness is not only a guarantee of product quality, but also a guarantee of after-sales service. In the future, maintenance, repairs, etc. will not be difficult for us consumers.

Next is the specifications and parameters of the cooling fan. According to your own needs, you can purchase it based on what functions you need, how much air volume and pressure you need, or whether you need something with low noise. Don't blindly pursue expensive or cheap products, otherwise you won't be able to use them when you buy them back, and you'll have to struggle. You must purchase products that suit you.
