Fans 4715KL-04W-B20 12V 0.52A 2650RPM 97CFM 41DBA case fan

120 mm double-ball-bearing case fan

This 120 mm case fan uses a double ball bearing and runs on 12 V at 0.52 A. It is built for system integrators and industrial buyers who need reliable airflow in servers, medical equipment or rail-vehicle enclosures. The fan suits builds that demand long bearing life under continuous operation. It is not for buyers who want RGB lighting or PWM speed control.

Fits standard 120 mm mounts with 38 mm depth

The frame measures 120 by 120 by 38 mm and draws a measured 0.4 A in use. It connects via a two-wire 12 V supply, so it needs no motherboard header or controller. The simple wiring frees up fan headers for other components and works with any 12 V rail. Builders who require variable speed or a four-pin connector must look elsewhere.

Steady 2650 RPM delivering 97 CFM at 41 dBA

At full voltage the fan holds 2650 RPM, moving 97 CFM while producing 41 dBA of noise. Double ball bearings maintain consistent speed and airflow during extended duty cycles in drive-cooling or industrial-cleaning applications. The design targets stable thermal performance rather than quiet acoustics. Users who prioritise silent operation over sustained throughput should consider different models.
