Connector: Big 4 Pins Connector Product Name: Computer Case Cooling Fan Rated Voltage: DC 12V Rated Current: 0.25A Power consumption: approximately 3 W Overview This computer case cooling fan provides reliable airflow to help maintain safe operating temperatures for system components. It uses a 4pin connector and runs on a DC 12V supply with a current rating of 0.25A, delivering steady performance suitable for typical PC builds. Key benefits Simple installation: The big 4pin connector allows straightforward plugin to compatible headers or power sources. Consistent performance: Designed for stable 12V DC operation to support continuous cooling needs. Efficient power usage: With a current draw of 0.25 A, the fan delivers effective airflow while keeping power consumption modest (approximately 3 W). Clear compatibility signal: The 4pin connector aligns with common PC case fan wiring, supporting standard installation in computer cases. Function and performance Function: Moves air through the computer case to remove heat and help maintain component temperatures. Performance attributes: DC 12V operation, 0.25A current rating, enabling reliable cooling in typical desktop environments. Compatibility and use considerations Compatibility: Intended for use with devices that accept a 4pin connector and a 12V DC supply (standard PC case fan usage). Installation note: Verify that the system power source or motherboard provides a 12V supply and has a compatible 4pin connector before installation. Use scenarios Desktop PC upgrade: a failed or undersized case fan in a midtower build to improve airflow and cooling performance. Small form factor or compact systems: Install in miniITX or small chassis setups where efficient cooling is needed within limited space. Home server or media center: Use to maintain steady airflow in compact servers or HTPCs that operate continuously and generate heat. Maintenance and care Minimal maintenance required; inspect connectors and cables during routine maintenance and if damaged. Ensure power supply and connectors remain clean and of debris to maintain reliable operation.
