. The new redeveloped blades in PH-F120SP are angled lower to achieve higher air pressure. The redesigned MVB blades generate better airflow & produces better performance. It improves the balance of airflow & air pressure when using with as a case fan. The PH-F120SP has a larger base size with 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 the PH-F120SP. 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 & frame rib for lower wind & vibration noise..
