Sanyo 12V High-Speed Server Fan

The SXDOOL 9CRA0412P5J04 is a 4cm Sanyo DC cooling fan built for server environments that demand high airflow in a compact frame. It runs on a nominal 12V supply with a rated current of 1.4A and spins at up to 14700 rpm. Four ball bearings support the rotor for durable operation under continuous load. The 8-pin small plug carries power, ground and speed-sense wires for monitoring.

Suited for Dense Server Chassis.

This fan targets administrators who need strong airflow in tight 4056-form-factor bays and who can accommodate 81.9 dBA of operating noise. It is not appropriate for workstations, home servers or any chassis where low acoustic output is a requirement. Buyers without an 8-pin header matching the red-orange positive, gray-black negative and yellow-purple tachometer layout should look elsewhere.

14700 RPM Airflow Headroom and Monitoring

At 14700 rpm the fan delivers the large air volume specified for booster-class server cooling, with speed detection and locked-rotor protection providing real-time health feedback. The 6-14V working range gives some voltage headroom, but the 81.9 dBA noise floor means acoustic headroom is effectively zero for noise-sensitive racks. The 92g weight and 4x4x5.6cm footprint fit standard 4056 mounting patterns.

Questions about this item

What power supply connector do I need for the 8-pin plug on this SXDOOL 9CRA0412P5J04 fan?

The fan uses an 8p8 wire small plug with red and orange wires for positive, gray and black for negative, and yellow and purple for speed detection.

Will the 14700 rpm speed and 81.9 dBA noise level overwhelm quieter components in my older server chassis?

At 14700 rpm the fan produces 81.9 dBA, so it is significantly louder than typical low-speed case fans and will dominate the acoustic profile.

How can I verify the fan is running correctly after connecting the yellow and purple speed wires?

The yellow and purple wires provide a tachometer signal; monitor the reported RPM in BIOS or fan-control software to confirm it reaches up to 14700 rpm.
