High-speed 120 mm PWM case fan

The SXDOOL PSD1212PMBX is a 120 mm axial fan built for high-static-pressure cooling. It runs at 6000 RPM on a 12 V supply and draws 36 W through a standard 4-pin PWM connector. Double ball bearings support continuous operation in dense airflow paths.

Suited for mining rigs and tight enclosures

This unit targets builders who need maximum airflow through restrictive heatsinks or chassis meshes. The 38 mm thickness and high power draw make it unsuitable for slim cases, low-noise builds or standard desktop cooling where lower RPM units are preferred.

Delivers 226.5 CFM at full speed

At 6000 RPM the fan moves over 226 CFM, giving strong headroom for multi-GPU mining frames or server-grade heat loads. Airflow drops sharply when PWM duty is reduced, so it cannot serve as a quiet idle fan. The 92 mm spec listed elsewhere appears inconsistent with the 120 mm frame.

Questions about this item

Do I need a 12 V power header rated for 36 W to run the PSD1212PMBX?

Yes, the fan draws 36 W at 12 V, so the motherboard or controller header must supply that power.

Can the 4-pin PWM connector control speed down to the 6000 RPM floor on a standard motherboard header?

The 4-pin PWM interface lets the board regulate speed, but the motor's operating range starts at 6000 RPM and runs up to 6499 RPM.

How can I confirm the fan is delivering the rated 226.5 CFM after installation?

With the fan at full 6000 RPM you should measure airflow near 226.5 CFM; a hardware monitor showing 6000 RPM and strong exhaust pressure indicates it is working as specified.
