The LC-CF-80 from LC-Power is a powerful 80 mm case fan. This simple fan made of black plastic features seven fan blades, allowing for an airflow of up to 34.25 CFM at 2200 RPM. The power supply and thermally controlled operation of the fan are managed via a 4-pin PWM connector. It operates quietly with a noise level of 15.7 - 29.5 dB(A). The hydrodynamic bearing makes the fan highly efficient, significantly increases its lifespan, and, in combination with the anti-vibration washers, ensures particularly quiet operation. This case fan allows for speed control through pulse width modulation using a PWM-capable motherboard. As a result, the fan speed is dynamically adjusted to the current operating conditions, minimizing unnecessary noise generation.
