How to deal with common faults of DC fans?
DC fans have become very common in our daily lives, such as laptops and computer hosts, which require the use of heat sink fans. However, when we use DC cooling fans, there are undoubtedly some common malfunctions. Therefore, how should we deal with DC cooling fans when they have problems?
1. When in use, the DC fan suddenly emits a very loud noise, sometimes even much louder than the sound of the chassis power supply.
Solution: This kind of thing is usually caused by the lubricating grease on the fan or the fan being dusty. Just separate the heat pipe radiator from the fan, clean the fan, wipe it, and apply a little lubricating grease.
2. During the use of the fan, it moved in its own direction.
Solution: This kind of thing must be due to the broken buckle of the fixed fan, just replace it.
3. When the fan rotates, there is a "dada dada" knocking sound.
Solution: This is also caused by the wind turbine encountering wires. It is necessary to use rubber bands or other materials to tie up the scattered wires satisfactorily.

Can you explain what determines the price of a DC fan?
At present, there are various brands and styles of DC fans on the market, making it difficult to choose. However, it is puzzling that manufacturers of different types of DC fans will come up with different prices, which are not consistent. This can be a bit difficult for some new buyers and sellers in the industry because they are not familiar with the truth or falsehood of the price. To tell you this, the price of DC fans is generally determined by the following aspects.
1. Materials used
In terms of materials, PBT is generally used as the plastic material for micro fans, which has good high temperature resistance and flexibility. However, some require secondary or tertiary materials, and the characteristics of this recycled material are only slightly inferior, so the price will be more favorable.
2. Rolling bearings
From the perspective of rolling bearings, there are generally two types of steel balls with a total oil content. Generally speaking, steel balls are slightly more expensive than those with oil content, and rolling bearings are developed after oil containing bearings, with a longer service life and more complex processing technology
3. Materials
In terms of material, there are generally plastic, iron, copper, aluminum, and some even better ones are silver. The better the material, the more naturally the price will be, which goes without saying. In addition, there are specifications. The more specifications there are, the larger the material used, which will be more expensive.
4. Brand
As is well known, products from big brands are much more expensive. In the end, well-known brands not only have quality assurance, but also guarantee after-sales service, so the natural price is slightly higher.
