  • What is the service life of the brushless fan?

    Brushless fans are popular in the market due to their high efficiency, long life and low maintenance costs. Compared with the traditional brush fan, the brushless fan does not have the friction of the brush and the commutator, so the service life of the fan is greatly extended. Brushless exhaust fans produced by Chungfo Electronics perform well in a variety of applications, especially for heat dissipation and exhaust in high temperature environments.

    How long is the service life of the brushless fan? Generally speaking, the life of brushless fans can reach more than 50,000 hours, and even longer use time can be achieved under certain conditions. This is mainly due to its frictionless design and efficient heat dissipation.


    When choosing a brushless exhaust fan, price and life are important factors to consider. For users who need small exhaust fans, the Chungfo Electronics’s small exhaust fan price is not only reasonable, but also has significant advantages in performance and durability. In addition, we also provide high temp exhaust fan Wholesale to meet a wide range of industrial and commercial needs.


    In conclusion, the long life of brushless fans makes them ideal for many applications, especially in environments where long-term stable operation is required. Contact Chungfo Electronics to learn more about brushless fans and other cooling solutions.

  • What kind of design cooling fan can read the tach signal through GPIO?

    Typically, the cooling fan is connected to the system through a three-wire interface, which includes a power cable, a ground cable, and a Tach cable (speed signal cable). In order to be able to read Tach signals through GPIO, you need to select a fan that supports this feature. Such fans are often referred to as "ach-enabled" (supporting Tach) or "RPM-sensing" (supporting speed detection) fans.

    The Tach signal is a pulse signal whose frequency is proportional to the speed of the fan. Typically, a pulse signal is generated for each rotational speed cycle. Here are some steps to help you implement a cooling fan that reads Tach signals via GPIO:

    1, Make sure that the fan you choose supports Tach function or speed detection function. You can find this information in the fan specifications and instructions.




    2. Connect the Tach wire of the fan to the available GPIO pin. This usually requires the use of cables or connectors.




    3, Use the appropriate hardware interface circuit to convert the fan's Tach signal into a digital signal that can be read. This is because GPIO typically operates at the digital signal level.
