Phanteks 1200RPM 140mm Case Fan with ON/OFF Switch 400mm Extension Cable R

The new redeveloped blades in PH-F140SP_BK_GLED are angled lower to achieve higher air pressure. The redesigned MVB blades generate better performance and better airflow. It improves the balance of airflow and air pressure when using with as a case fan.. Air flow - 82.1 CFM. Noise level - 19.0 decibels
The PH-F140SP has a larger base size with a magnetic brushless DC motor to avoid the effects of resonance and for rotational stability.
To create better structural strength and reduce the vibration occurrence, Phanteks redesigned the back frame of the PH-F140SP_BK_GLED.
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.
The new nine 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 to create significantly better performance and airflow while keeping noise to a minimum.
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.
Eight pre-installed rubber pads are now bigger and designed to reduce more vibration.
