Phanteks 140mm LED Case Fan with 400mm Extension Cable (PH-F140SP_BK_BLED) The new 9 high pressure MVB blades are precisely angled to generate a silent controlled airflow. The blades produces a downdraft vortex allowing for greater amount of air passage through and reduce airflow turbulence across the surface of the blades Composed by MOSS and SSC systems, Phanteks' UFB bearings have an effective hub-tip ratio to achieve a state of equilibrium reducing air and vibration noise. Phanteks PH-F140SP_BK_BLED comes bundled with a 400mm extension cable to improve cable management, total up to 900mm cable length for big full-tower case or Radiator fan upgrade. Eight pre-installed rubber pads are now bigger and designed to reduce more vibration. PH-F140SP has a larger base size w/ a magnetic brushless DC motor to avoid the effects of resonance & for rotational stability. To create better structural strength & reduce the vibration occurrence, Phanteks redesigned the back frame of PH-F140SP_BK_BLED. With the noise reduction challenges in mind, we modified the component for lower actuator noise, PCBA for lower electromagnetic noise, brushless motor structure for lower operating noise and frame rib for lower wind and vibration noise.
