- 12 V 0.31 A rated draw limits power load
120mm PWM fan for water-cooling loops
The SXDOOL SAB4B2U is a 120mm case fan built for radiator and water-block mounting. It runs on 12V power and uses a dual ball bearing rated for continuous high-speed operation. The 4-pin PWM connector lets the motherboard or controller adjust speed automatically.
2700RPM maximum speed with 10% tolerance
At full duty the fan spins at 2700RPM with a rated current of 0.31A and a peak of 0.45A. The 25mm thickness fits standard 120mm fan mounts. Buyers who need a lower maximum speed or a 3-pin voltage-controlled header will not be served by this model.
Highlights

Questions about this item
How loud will the 2700 RPM fan be inside my case?
At 2700 RPM the fan moves more air but produces noticeable noise; PWM control lets the motherboard lower speed when full cooling is not needed.
What does the 4‑pin PWM connector actually control?
The fourth pin carries a pulse‑width signal so the board can vary voltage to the 12 V motor, adjusting speed between minimum and the 2750 RPM ceiling.
