A DC fan is a cooling device powered by direct current (DC) voltage, typically 5V, 12V, 24V, or 48V. It operates using a brushless DC motor (BLDC), which ensures high efficiency, low power consumption, and precise speed control.
Compared to AC fans, which run on alternating current and have a fixed speed depending on the frequency, DC fans offer better energy efficiency, quieter operation, and longer lifespan due to reduced friction and wear.
On the other hand, EC fans (electronically commutated fans) combine the advantages of both AC and DC fans. They use an AC power source but internally convert it to DC, allowing for higher efficiency, variable speed control, and lower energy consumption. However, EC fans tend to be more expensive and are primarily used in applications where energy savings and intelligent control are critical.
A Brushless DC motor (BLDC) is a type of motor that eliminates the need for carbon brushes and a commutator. Instead of mechanical contact, it relies on an electronic controller to switch the current in the motor windings, ensuring smooth and efficient operation. This design significantly reduces wear and tear, making BLDC motors more durable and reliable. They are widely used in DC cooling fans, providing precise airflow control and long-lasting performance.

From the previous sections, you might have come to know what DC fan is and the differences between DC fan, AC fan and EC fan. Therefore, from the following sections, we will directly delve into the key considerations when selecting a DC fan for electronics cooling. These factors not only affect the cooling efficiency but also play a significant role in the stability and longevity of your equipment.
The cooling performance of a fan is primarily determined by two factors: airflow and static pressure.
Airflow (CFM) refers to the volume of air a fan can move in a given amount of time, typically measured in cubic feet per minute (CFM). A higher CFM indicates that the fan can move more air, which is crucial for cooling larger spaces or components with high heat output.
Static Pressure refers to the fan’s ability to overcome resistance in an enclosed or obstructed space. This is especially important in situations where airflow needs to move through filters, heat sinks, or tight spaces. A fan with high static pressure can push air through these obstacles, ensuring consistent and effective cooling even in restrictive environments.
In a DC fan specifications, the relationship between airflow and static pressure is often represented by a PQ curve. This curve is a graphical representation that shows how airflow (CFM) and static pressure (inches of water or Pa) are related at different operating points of the fan.
The P in PQ curve stands for Pressure, which refers to the static pressure.
The Q in PQ curve stands for Quantity, which refers to the airflow or volume of air the fan moves.
PQ curve is measured by air tunnel. The maximum air flow and static pressure are measured values under ideal conditions.
Max. air flow means there is no pressure difference between the air inlet and air outlet. Max. air pressure means the difference between inside and outside of wind tunnel till the air flow is zero when the fan blows the air into the air tunnel.
The relationship between them is the air flow decreases with the increase of the static pressure.
By adjusting the Nozzle and the Auxiliary Blower, to control the air volume, record the corresponding difference values between Air Flow and Static Pressure, then finally draw the pressure-flow diagram, saying PQ curve diagram.
However, most of the people select DC fans by referring to its maximum airflow and static pressure, which is not the correct concept since maximum air flow and static pressure are tested under ideal conditions (lab condition), which doesn’t exist in real applications since there is always impedance in your system.
By obtaining the fan’s PQ curve, and combining it with the your system impedance curve, we can identify the operating point (OP) for your system. This is the point where the fan’s PQ curve and the system’s impedance curve intersect.
For examples, as the figure shown as above, maximum airflow and static pressure of Fan A is higher than Fan B. However, since the intersection of Fan B PQ is higher than Fan A, Fan B is better solution.
For high-impedance systems, high-pressure DC fan can be selected. Whereas, for low impedance systems, it is better to choose a high-airflow fan. As shown in above figure, for S system, fan A with high air pressure will be better; for S’ system, fan B with high air volume will be more suitable.
Usually, we can’t measure system impedance very accurately. So, it’s a good idea to pick a cooling fan that can handle 1.5 to 2 times more airflow than your need. When choosing a fan, just looking at the maximum airflow listed in the specs isn’t enough. Airflow isn’t the only factor in measuring cooling effectiveness. It’s also important to choose the right cooling fan based on the system’s impedance.
The Bearing system is the “heart” of DC fan, which, to a large extent, determines the fan lifespan. At Procool, there are two main bearing systems, sleeve bearing and dual ball bearing. The most difference between sleeve bearing and dual ball bearing is fan lifespan.
Sleeve-bearing fan lifetime is 20000-30000 hours at 40C.
Dual-ball-bearing fan lifetime is 50000-70000hours at 40C.
The root cause to get different lifespan is resulted from its working principle.
Sleeve Bearing: The impeller shaft of the sleeve bearing fan is wrapped in a sleeve-like structure and is added with lubricating oil for easy rotation, which is a type of line contact, saying the contact surface area between its moving parts is actually quite large. Since the sleeve bearing gets more friction between shaft and bearing inner wall, they need lubricanting oil to reduce the frictions.
Ball bearing fan is designed with a ring of balls around the shaft, which is a type of point contact for less friction. The design of ball bearings reduces friction by replacing sliding motion with rolling motion. Instead of two surfaces rubbing against each other, the balls roll between the races, creating less friction and reducing wear on the bearing. The races are also typically machined to precise tolerances to ensure proper fit and alignment, further reducing friction and increasing efficiency.
