Experience Exceptional Cooling with the 120x25mm High-Performance Brushless DC Fan

In the realm of advanced electronics and mission-critical systems, effective heat management is an absolute necessity. We present a cooling solution engineered for excellence: the 120x120x25mm high-speed brushless DC fan.

This DC fan is engineered for situations demanding dependability and strong airflow, showcasing a durable construction and top-tier performance. It provides the necessary cooling capacity to ensure peak operation, stability, and longevity for your valuable components, whether in a dense server, an industrial cabinet, or a power-intensive electronics project.

Optimal Operation in Challenging Environments

The core design of this DC fan enables it to displace a substantial volume of air while overcoming significant system resistance. It produces an impressive maximum airflow reaching 130.1 CFM (approximately 3.68 cubic meters per minute). Such high-volume air movement is crucial for quickly removing heat from focused areas, making it perfectly suited for cooling processors, graphics cards, power units, and other densely packed electronic assemblies.

Equally important is its exceptional static pressure, which reaches a maximum of 16.14 mmH₂O (0.64 inchH₂O). This metric indicates the fan's power to force air through restrictive environments like tightly finned heatsinks, dense chassis filters, or enclosures with intricate internal layouts. Its high-pressure capability ensures cool air reaches critical parts even within systems that have substantial airflow impedance, a condition where conventional fans might fail.

An examination of the performance (P&Q) curve reveals the fan's balanced capabilities, as it sustains strong airflow even with increasing back-pressure. This guarantees efficient cooling across diverse operating scenarios.

Built for Durability and Steadfast Reliability

Reliability is a fundamental aspect of this DC fan's design, starting with its advanced dual ball bearing system. In contrast to standard sleeve bearings, dual ball bearings provide a markedly extended operational lifespan, decreased friction, and flawless performance at elevated temperatures. These features make it the ideal choice for continuous, round-the-clock use and for environments where maintenance access is limited and dependability is paramount.

Moreover, the ball bearing configuration permits the fan to be installed in any orientation—be it horizontal, vertical, or at an angle—without negatively affecting its operational effectiveness or longevity.

Its inherent robustness is further enhanced by a broad operating temperature range, from a cold -10°C up to a hot +70°C (14°F to 158°F). This versatility ensures consistent operation in environments lacking climate control. For storage, the fan can withstand temperatures between -40°C and +80°C, preserving its integrity during shipping and before it is installed.

The fan's physical construction is equally resilient. Its frame and seven-blade impeller are both molded from high-grade Thermal Plastic rated UL 94V-0 for flammability. This classification signifies that the material will extinguish itself and provides outstanding fire resistance, adding a critical safety measure to any electronics assembly.

Smart Protection and Flexible Integration

To safeguard the fan and the equipment it cools, crucial motor protection features are built-in. Impedance protection ensures the motor is safe from burnout should the blades become obstructed. Additionally, reverse polarity protection guards against catastrophic failure from incorrect wiring during setup. These integrated safeguards offer peace of mind and help reduce the overall ownership cost.

Flexibility is a key consideration for system builders, and this DC fan provides it through several available configurations:

• Voltage Varieties: Offered in 12V, 24V, and 48V DC versions, it integrates smoothly into a wide array of power architectures, from consumer and automotive uses to industrial and telecom equipment.

• Performance Levels: The DC fan is available in distinct tiers to address particular requirements. You can opt for ultra-high-speed variants that run up to 5300 RPM for ultimate cooling in the most thermally intense situations. As an alternative, high-speed models at a quieter 4000 RPM present a formidable mix of robust airflow (108.1 CFM) and lower acoustics (50 dBA) for applications sensitive to noise.

For enhanced system monitoring and control, optional features can be included. These are PWM (Pulse Width Modulation) for speed adjustment, FG (Frequency Generator) tachometer output for monitoring rotation, and RD (Rotation Detector) alarm signals for locked-rotor alerts, facilitating dynamic and intelligent thermal solutions.

Ideal Use Cases

This 120mm DC fan's combination of powerful airflow, high static pressure, and durable construction makes it a perfect cooling solution across a wide spectrum of uses, including:

• Servers and Data Centers: Cooling for rack-mounted servers, network switches, and storage arrays.

• Industrial Automation: Cabinet, PLC, and motor drive ventilation to avert failures caused by heat.

• Telecommunications: Maintaining the reliability of base stations, routers, and other network equipment.

• High-Power Electronics: Cooling for large inverters, welding machines, and power supplies.

• DIY and Enthusiast Projects: Excellent for high-performance computer builds, laser cutters, 3D printers, and custom ventilation systems that require exceptional cooling.

Featuring a standard 120x120mm frame size, a slender 25mm depth, and a 105x105mm mounting pattern, the fan serves as a direct replacement or upgrade for most common uses, simplifying system improvements. To summarize, this high-speed brushless DC fan represents more than a mere component; it is an assurance of stability, an enabler of peak performance, and a lasting investment in your electronic systems' reliability.
