The Gamemax GMX-14WFBK-PWM is a 140mm PC case fan designed to maintain a steady airflow within your computer chassis. It features a 4-pin PWM connector that allows your system to automatically adjust the speed between 600 and 1400 RPM based on the current thermal load, ensuring a balance between cooling performance and acoustic comfort. Built with a hydrodynamic bearing, this black fan is engineered for stability and a lifespan of approximately 30,000 hours. Its nine-blade design generates an airflow of 43 CFM and a static pressure of 1.83 mm-H2O, while keeping noise levels around 30 dBA. Measuring 140 x 140 x 25 mm, it fits standard case mounts and is a practical choice for users who prefer a clean, non-illuminated look for their build.
