 In a high temperature environment, have you ever worried about the durability of the fan? Now, you can rest assured to choose our all-Metal Fan-15055. It is designed to cope with extreme temperatures and can withstand ambient temperatures of over 100 degrees, making it an ideal companion for your high-heat products.

When choosing a Cooling Fan, we often come across two core parameters: maximum air flow  and maximum static pressure . So, in practical applications, which parameter is more important? Does a higher air volume lead to better heat dissipation, or does a stronger static pressure make the fan play a greater role? Let's delve into an in-depth analysis.

With the widespread adoption of LED technology, fans, as a critical component of the LED lighting heat dissipation system, have garnered significant attention. Inadequate heat dissipation has emerged as a prevalent issue affecting LED lights, and the quality of the fan directly influences key factors such as lifespan, light attenuation performance, and operational stability. Given the extensive range of fan products available in the market, selecting an appropriate fan for LED lights to ensure prolonged and stable operation of the lamps can be challenging. Today, we present essential guidelines for choosing LED fans, ensuring you avoid common pitfalls and select the most suitable heat dissipation solution.

In the operation monitoring of cooling fans, the FG signal (Frequency Generator Signal, frequency signal) is like the "heartbeat" of the fan, providing real-time feedback on the fan's rotational speed. It not only serves as a "barometer" of the fan's performance but also plays a crucial role in ensuring the safe operation of industrial equipment. However, when the FG signal becomes unstable, will the cooling fan experience "fluctuations" or even fail? This article will delve into the significant role of the FG signal and the impact of its instability on the fan.

Cooling fans are typically designed with two, three, or four wires. Four-wire fans support PWM-based speed regulation and feedback, which makes them widely applicable in various scenarios. However, during actual installation, users may only require a subset of the fan's functionalities, leading to situations where a four-wire fan is connected using only three wires. This article aims to provide a detailed explanation of how to connect only three of the four wires of a cooling fan, along with important precautions to consider.

In fields such as smart hardware, communication equipment, power systems, energy storage facilities, and industrial automation, the stability of cooling fans directly impacts the performance and safety of the entire system. Traditional methods for assessing fan status are primarily limited to binary logic—whether the fan is powered on or off, and whether it is rotating or not. However, this simplistic approach fails to meet modern equipment requirements for predictive maintenance and intelligent diagnostics. The FG signal (Frequency Generator), which is widely integrated into fans, is increasingly becoming a critical channel for achieving "fan-level intelligent diagnosis." It can not only provide real-time rotational speed data but also reflect changes in operational status, detect fault trends, and assist in health assessments. This raises the question: Can the FG signal truly support the task of "intelligent diagnosis"? This article will conduct an in-depth analysis from three perspectives: principle, methodology, and application.

In coastal and highly corrosive environments, salt spray corrosion not only compromises the mechanical integrity and electrical performance of fans but also significantly reduces the stable operational lifespan of equipment. Consequently, the salt spray protection capability of cooling fans is of critical importance. Selecting an appropriate salt spray protection level has become an essential requirement to ensure the quality and safe operation of cooling fans. This article aims to analyze the significance of salt spray protection and provide guidance on its proper selection.

With the growing demand for enhanced heat dissipation efficiency and energy-saving performance in electronic devices, PWM (Pulse Width Modulation) speed regulation technology has emerged as a critical feature of cooling fans. Cooling fans equipped with PWM speed regulation, which offer precise and efficient speed control, have been extensively adopted in servers, communication equipment, industrial automation, and other related domains.

Cooling fans in electronic devices serve not only as a means of thermal dissipation but also function as temperature monitoring systems. With technological advancements, many modern cooling fans are now equipped with temperature sensors that can detect the ambient or equipment temperature in real time and make corresponding adjustments accordingly. This raises two critical questions: how do these integrated temperature sensors "detect" temperature? And how do they influence the operational status of the cooling fan?
