Using magnetic levitation technology, the Asus ROG Strix XF 120 case fan is ambitious about silence.
Asus is preparing to launch the first PC case fan model called the ROG Strix XF 120. For its first entry into the fan market, Asus opted for “whisper-quiet” magnetic lift bearings. It is also among the information that the sound level of the Asus ROG Strix XF 120 is at 22.5 decibels. The chart prepared by Yale University shows that 22.5 decibels lie between a quiet natural space without wind (20 dB) and a whisper (25 dB).
Magnetic levitation directly plays a role in the low noise claim. Fan blades mainly move around magnetic bearings so there is no physical contact or friction. While there is some friction caused by wind resistance, this generally results in lower noise than sleeve, ball or fluid dynamic bearings. An added benefit of magnetic levitation is that there is no lubricant that will wear out over time.
The ROG Strix XF 120 was announced in September last year, but no information was given about the price or release date. Asus has finally announced on Twitter that the ROG Strix XF 120 will be available in April. The price issue is still open. On some pre-order sites, the price appears to be around $ 29.
As the name suggests, it is a 120 mm fan. With an operating range of 250 to 1,800 RPM, the fan has a 4-pin cable; namely PWM supported. Asus rates the airflow at 62.5 CFM and the lifetime at 400,000 hours. In addition to using magnetic lift bearings, the fan also uses specially grooved blades and anti-vibration design. Also, the logo in the center appears to have RGB lighting.
