Описание товара на английском языке:
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.
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.
With 4 LEDs attached to the PH-F140SP_BK_LED, these fans will make any case more aesthetically appealing. The ON/OFF switch allows user to enable or disable the LEDs.
