High-speed 120 mm case fan

The SXDOOL g1238c12b8zp-c5 is a 120 x 120 x 38 mm case fan built for systems that demand strong airflow. It runs on 12 V and draws 1.85 A for a rated power of 20 W. The ball bearing supports a speed range of 800 to 6300 RPM with a tolerance of ±10 %. This fan targets builders who need high static pressure in a standard 120 mm mounting footprint.

PWM control via 4-pin connector

A four-pin power connector enables motherboard PWM speed regulation so the fan can scale between its minimum and maximum speeds automatically. No separate controller or software utility is required; the standard PWM signal handles the adjustment. The bundled function is limited to this speed regulation and does not add lighting control or additional monitoring features.

Limits of the 120 x 38 mm form factor

The 38 mm thickness exceeds the 25 mm depth common in many chassis, so clearance at the front, top or rear panel must be verified before installation. At full speed the fan produces 52 dBA of noise, which is audible in quiet environments. The 4-pin PWM interface relies on motherboard header support; boards without a fourth pin will run the fan at fixed voltage instead of variable speed.

Questions about this item

How often will the ball bearing in this 120x120x38mm fan need replacement?

The ball bearing is rated for continuous operation at up to 6300 RPM; typical service life exceeds several years under normal case temperatures, so replacement is rarely needed during a standard build cycle.

What limits sustained airflow before the 250 CFM rating drops?

The 20 W power draw and 1.85 A current set the thermal ceiling; if the 12 V supply cannot maintain voltage under load, speed will throttle below the 800-6300 RPM range and airflow will fall.

How loud and hot does the 12 V 1.85 A motor get when running all day at 6300 RPM?

At full PWM duty the fan produces 52 dBA and moves air at 12.8 m/s with 1.1 inH2O pressure; the motor draws 20 W, so case airflow must remove that heat to keep temperatures stable.
