• With dimensions of 120mm x 120mm x 25mm, this fan is a standard size commonly found in desktop computers, server cases, and industrial equipment. The 25mm thickness provides enough space for larger blades, contributing to improved airflow without sacrificing quiet operation. The 120mm diameter ensures it provides ample cooling, especially for more powerful systems.

• The fan operates on a 12V DC (Direct Current) power supply, which is the standard voltage for many small electronic cooling fans, including those used in PCs, industrial systems, and consumer electronics. It is powered either directly from a PC power supply, external 12V adapter, or through a motherboard fan header (with a corresponding 12V DC input).

• This fan typically provides excellent airflow in the range of 40-100 CFM (Cubic Feet per Minute) depending on the specific model. The higher airflow ensures that heat is effectively carried away from critical components like the CPU, GPU, and other internal parts of your system, preventing overheating and ensuring stability.

• The fan’s static pressure (measured in mmH2O) will also play a role in its effectiveness, especially when cooling through filters, heatsinks, or radiators, where pressure is more important than raw airflow.

• Fans in this size typically operate at speeds between 1200 to 3000 RPM (Revolutions Per Minute). This range strikes a balance between high airflow and relatively quiet operation, ensuring effective cooling without excessive noise.

• Some models may feature PWM (Pulse Width Modulation) support, allowing the fan’s speed to adjust dynamically based on the system’s temperature, offering optimized cooling and reduced noise during idle periods.

• Many modern 120mm fans are designed to run quietly by incorporating features like fluid dynamic bearings (FDB), sleeve bearings, or ball bearings, depending on the fan. These bearing types help reduce friction and vibrations, leading to quieter operation. Noise levels will vary depending on the RPM and design, but many fans are engineered to maintain noise levels below 30 dBA at medium speeds.

• This fan is usually built with high-quality materials, such as durable plastic and metal bearings, ensuring long-term reliability and a long lifespan, especially under continuous operation. Fans designed for PCs or industrial use can often run for thousands of hours before showing signs of wear.
