SXDOOL 120 mm PWM case fan
The SXDOOL XF-12025-SD-K is a 120 mm by 25 mm case fan that runs on a 4-pin PWM header at 12 V. It suits builders who want a single fan for intake or exhaust in a standard chassis.
4-pin PWM control and hydraulic bearing
The 4-pin connector allows the motherboard to vary speed automatically, so the fan runs only as fast as needed. A hydraulic bearing reduces friction, helping the unit stay quiet at low RPM while still delivering 74.5 CFM airflow and 2.15 mmH₂O static pressure when the curve ramps up.
Upgrade from fixed-speed or sleeve-bearing fans
Replacing a 3-pin fixed-speed fan or an older sleeve-bearing model removes the constant drone and lets the system idle near 18 dB(A). The jump is worth it when you want PWM control and a longer bearing life without changing mounting points.

Questions about this item
How much airflow does the XF-12025-SD-K deliver at its top speed?
The fan moves 74.5 CFM of air at maximum RPM, providing strong case ventilation for both air and water cooling setups.
What noise level should I expect when the fan runs continuously at full load?
At peak speed the hydraulic bearing produces 35.2 dB(A), while idle or low-speed operation drops to around 18 dB(A).
Which motherboard header is required to control the XF-12025-SD-K?
A standard 4-pin PWM header supplying 12 V DC is needed for automatic speed control and monitoring.
