Fan FAQs

What's fan PQ curve?

The PQ curve, namely the pressure-air volume curve, is a core performance graph for cooling fans. Here, P represents air pressure (units: Pa, mmH₂O), and Q represents air volume (units: CFM, m³/h). It illustrates the actual air volume a fan can deliver under different duct impedance (static pressure) conditions.A fan’s maximum air volume and pressure are measured under extreme conditions, but in real scenarios, fans operate in resistive environments. The actual air volume is determined by the intersection of the fan’s PQ curve and the system duct resistance curve, which is parabolic—resistance is proportional to the square of air volume. Only when the fan’s PQ curve matches the system resistance curve can it ensure sufficient air volume for efficient heat dissipation; otherwise, it may cause insufficient airflow and increased noise.

Why can't we just focus on the maximum air volume or maximum air pressure?

Many engineers often only focus on the maximum air volume and maximum air pressure of the fan when selecting, believing that “the larger the air volume, the better, and the higher the air pressure, the stronger”. But this kind of cognition has serious misconceptions! The maximum air volume of the fan is measured under ideal conditions of “zero impedance” (fully open air outlet); The maximum wind pressure is the test result when the air outlet is completely closed (with zero air volume). However, in practical applications, fans always operate in environments with resistance, and their actual airflow performance depends on the intersection of the PQ curve and the system resistance curve.

How to achieve precise matching between fan PQ curve and system resistance curve?

The system air duct also has a resistance curve, which is usually parabolic in shape, meaning that the resistance is proportional to the square of the air volume – the larger the air volume, the more rapidly the resistance increases. The core of selection lies in accurately finding the intersection point between the fan PQ curve and the system resistance curve. This intersection directly determines: The actual output air volume of the fan in the system; Can it meet the cooling needs of the equipment; Whether the operation process is stable, quiet, and efficient. If the matching is successful, the heat dissipation efficiency will be greatly improved and the equipment will run smoothly; On the contrary, it will lead to insufficient air flow, increased noise, and continuous accumulation of heat.

How to Reasonably Match "Wind Pressure+Impedance" Practical Steps

Evaluate the system’s air duct resistanceSimulation modeling: Step1,using professional software such as CFD to simulate the system’s air duct;Empirical judgment: For example, the combination of high-density radiators and filter screens usually has a resistance of 100-150Pa;Real machine testing: Use differential pressure gauges and anemometers to directly measure the actual wind resistance of the system.Step 2: Refer to the fan PQ curve diagramRequest the PQ curve of the fan from the supplier or check it on the official website;Confirm whether the air volume of the fan can meet the design requirements at the corresponding point of system resistance.Step 3: Compare multiple models and select the best solutionChoose the fan model that performs best at the intersection point, which must meet the following requirements:The effective air volume meets or exceeds the minimum cooling requirements of the equipment;Leave a safety margin of 15% -30% for wind pressure;The operating range is located in the middle section of the PQ curve, avoiding working in extreme high voltage or high current areas to reduce noise and losses.

What is PWM control function of a fan?

PWM (Pulse Width Modulation) is a technology that adjusts the fan speed by controlling the current by adjusting the width of the signal. Unlike traditional voltage regulation methods, PWM control precisely controls the fan speed by adjusting the duty cycle of the signal (i.e. the ratio of high and low signal levels). This technology is widely used in cooling fans, fans, and various electric devices. The working principle of PWM control: By changing the duty cycle of the PWM signal, the operating speed of the motor is controlled. The frequency of the voltage “switch” remains unchanged during the signal cycle, and only the proportion of the “on time” to the total time is adjusted. This control method is not only precise, but also efficient and can reduce energy consumption. Main advantages: Energy saving and consumption reduction: Real time adjustment of fan speed based on equipment temperature to avoid excessive energy consumption. Noise reduction function: When the fan speed decreases, the noise also decreases, making it suitable for places with strict noise requirements. Extend service life: Accurately control wind speed, avoid frequent start stop, and reduce mechanical wear.

Application of PWM function fans in servers and data centers?

Application background of intelligent temperature control and fan management: When servers in data centers operate at full capacity for a long time, the heat generated needs to be managed through an efficient cooling system. Traditional fans may not be able to accurately adjust according to temperature changes, resulting in unnecessary high-speed operation and increased energy consumption. Solution: Fans with PWM control can be connected to the temperature control system of the data center, and the fan speed can be automatically adjusted based on the real-time temperature of the data center, ensuring efficient heat dissipation while reducing energy waste and noise pollution. Application case: Cloud computing servers: Cloud computing server clusters require 24-hour uninterrupted operation. By introducing a fan system with PWM control, the fan speed can be dynamically adjusted according to the ambient temperature and server load, reducing energy consumption while maintaining the server temperature within the optimal operating range. Large data centers: Multiple servers and network devices are placed side by side, making heat dissipation an important challenge. By controlling fans through PWM, data centers can achieve more precise temperature control management, avoiding system failures or performance degradation caused by high temperatures.

Is there a minimum operating temperature limit for a fan?

Cooling fans are essential components in electronic devices, which dissipate heat by moving air to ensure the normal operation of the equipment. However, the operating temperature of cooling fans is not unlimited, they have minimum and maximum limits. The core of a cooling fan is the motor, and the coils and magnets of the motor are very sensitive to temperature. Under low temperature conditions, the lubricant of the motor may become viscous, increasing the resistance during startup and causing the motor to be difficult to start or overloaded. At high temperatures, the insulation material of the motor may degrade, increasing the risk of short circuits. For example, at -10 ° C, the viscosity of the lubricant increases by 30%, resulting in an increase in starting current. The blades and frame of a fan are usually made of plastic, metal, or other synthetic materials. These materials will expand or contract when the temperature changes. Extreme low temperatures may cause materials to become fragile and prone to rupture. Extreme high temperatures may cause material deformation, affecting the balance and efficiency of the fan. For example, the hardness of aluminum alloy increases by about 15% at -40 ° C compared to 20 ° C, while deformation may occur at 100 ° C.

For example, the hardness of aluminum alloy increases by about 15% at -40 ° C compared to 20 ° C, while deformation may occur at 100 ° C; Fans dissipate heat by moving air. The density of air decreases with decreasing temperature, which reduces the airflow and heat dissipation efficiency of the fan. In low-temperature environments, fans may not provide sufficient cooling effect. At high temperatures, the heat capacity of air increases, and fans require more energy to move the same volume of hot air. For example, the density of air at 0 ° C is about 8% lower than at 40 ° C. Our cooling fans typically operate within a temperature range of -20 ° C to 70 ° C and can be customized according to customer requirements.

Is it better to have a larger air volume for the cooling fan?

Airflow, usually measured in CFM (cubic feet per minute), is an important indicator of a fan’s heat dissipation capacity. However, facing the dazzling array of cooling fans on the market, a common question is: Is it really better to have a larger air volume?Firstly, we need to understand the importance of air volume. In theory, the larger the air volume, the more air the fan moves per unit time, thereby taking away more heat. This is particularly important for high-performance CPUs and GPUs as they generate a significant amount of heat during runtime. Therefore, in these situations, a large air flow cooling fan is undoubtedly beneficial. However, air volume is not the only consideration factor. Here are some other aspects to consider:Static pressure: Although air volume is important, if the static pressure provided by the fan is insufficient, it may not be able to effectively push air through dense heat sinks or overcome other resistance inside the chassis. Noise level: Generally, the larger the air volume of a fan, the greater the noise generated during operation. If noise is a sensitive factor, then it may be necessary to find a balance between air volume and noise. Energy consumption: Fans with high air volume often require more electricity to operate, which may increase the burden on the power supply and lead to a decrease in overall energy efficiency. Compatibility: The size of the fan and the compatibility of the chassis or cooling system are also very important. A fan that is too large may not be able to be installed in certain chassis or may conflict with other components. Actual requirements: Finally, consider the actual heat dissipation needs of your device. For some low-power or low heat dissipation devices, a medium air volume fan may be sufficient. In summary, the larger the air volume of the cooling fan, the better. When choosing a fan, it should be determined based on the specific requirements of the device, compatibility of the chassis, noise tolerance, energy consumption considerations, and budget. Sometimes, a fan with medium airflow but high static pressure and high efficiency may be a more suitable choice. Only by correctly matching the requirements of fans and equipment can the best heat dissipation effect and performance be achieved.

Why are the blades of the cooling fan odd?

As an indispensable cooling component in electronic devices, the design and performance of a cooling fan directly affect the stability and service life of the device. A notable phenomenon in the design of many cooling fans is that their number of blades is almost odd, such as 5, 7, or 9. Behind this design choice, there are profound principles of physics and engineering considerations. Resonance is an important concept in physics. When the frequency of the external driving force is close to the natural frequency of the system, the system will produce significant vibrations. In a cooling fan, if the number of blades is even and arranged symmetrically, resonance may occur between the blades at a specific speed. This resonance not only causes the fan to produce huge noise, but may also damage the fan blades or bearings due to the inability to withstand excessive vibration energy. In contrast, odd numbered fan blades, due to their asymmetrical arrangement, can effectively avoid the occurrence of this resonance phenomenon, thereby improving the stability and reliability of the fan. The cooling fan requires high-speed rotation during operation, so dynamic balance is crucial to its performance. Poor dynamic balance can lead to increased fan vibration, affecting heat dissipation and even shortening fan life. The design of odd numbered fan blades helps achieve better dynamic balance. During the manufacturing process, engineers can adjust parameters such as the mass distribution, shape, and angle of the fan blades to achieve dynamic stability during rotation, reducing vibration and noise. The working principle of a cooling fan is based on aerodynamics, and the design of the fan blades directly affects the flow of air and the heat dissipation effect. Odd numbered fan blades can distribute air flow more evenly during rotation, reducing airflow interference and vortex phenomena caused by symmetrical arrangement of fan blades. This design enables the fan to more effectively remove heat from the heat source, improving heat dissipation efficiency. In addition to technical considerations, the selection of the number of cooling fan blades is also subject to a balance between design and cost. Although even numbered fan blades can achieve good heat dissipation under certain specific conditions, their complexity in the production process, difficulty in adjusting dynamic balance, and performance stability of the final product may not be as good as odd numbered fan blades. In addition, with the continuous advancement of manufacturing technology and optimization of cost control, odd blade design has become a standard configuration in the cooling fan industry, which not only meets market demand but also ensures product competitiveness and reliability.
