Detailed Description:

The 4-Inch Cooling DC Fan is a high-performance, essential component for any project or device requiring efficient and reliable heat dissipation. This widely adopted size, which measures 120mm x 120mm, provides an optimal balance between powerful airflow and a compact form factor, making it the industry standard for everything from computer cases to industrial equipment. By actively circulating air, it effectively removes heat from sensitive components, preventing thermal throttling and extending the lifespan of your electronics.

A key technical advantage of this fan is its versatile power options. While many models operate on a standard 12V DC power supply, which is easily integrated into PC builds and many prototyping projects, options are also available for 5V, 24V, and even 48V applications. This flexibility ensures you can find the perfect fan to match your specific power source. Performance is measured by a fan's airflow, typically quantified in Cubic Feet per Minute (CFM), and its noise level, measured in dBA. High-performance versions can push over 100 CFM of air, while quieter models are designed for noise-sensitive applications, with sound ratings as low as 20 dBA. The fan's robust construction, often featuring a durable plastic frame and reliable bearings, ensures a long operational life. Whether you're building a custom PC, ventilating an electronic enclosure, or creating a DIY cooling system for a Raspberry Pi or other development board, the 4-Inch DC Fan is a professional and effective solution for all your thermal management needs.

This 4-inch (100mm x 100mm) DC cooling fan is a high-speed, low-noise exhaust fan designed for continuous airflow and optimal cooling performance. Available in 12V or 24V brushless motor versions, it is ideal for use in inverter enclosures, control panels, SMPS systems, 3D printers, and other temperature-sensitive electronics.

The fan comes with pre-drilled mounting holes, a 2-wire connection (red/black), and a durable plastic frame. It ensures silent operation, long life, and stable airflow, making it a preferred choice for both professional and hobby electronics cooling needs.
