Compact 40 mm server fan

The SXDOOL GM1204PKVX-8A is a 40 mm case fan built for tight server and workstation chassis. It runs on 12 V and draws 2.4 W through a simple two-pin connector. The black, non-LED frame measures 40 by 40 by 20 mm, fitting standard 4020 mounting points. It targets builders who need focused airflow in restricted spaces.

Sustained airflow at high speed

Ball-bearing construction keeps the rotor stable across the 5000 to 5499 RPM range during continuous operation. The design delivers 20 to 25 CFM without the wear patterns seen in sleeve bearings under constant load. Vibration stays consistent over long shifts in rackmount or blade environments. The two-wire feed provides steady voltage without PWM complexity.

Two-pin power only

The single specification that decides fit is the two-pin power connector, which supplies fixed 12 V with no speed reporting or PWM control. Buyers who need motherboard fan-curve management or tachometer feedback cannot use this unit. It suits always-on cooling where constant maximum airflow is acceptable. Check the header type before ordering.

Questions about this item

How much power does the 12V 2.4W motor draw when running continuously?

The fan is rated at 2.4 watts at 12 volts, so sustained operation draws that amount from the header.

Which motherboard header matches the 2-pin connector on this 40mm unit?

It plugs into any standard 12V two-pin fan header; no PWM or proprietary connector is required.

Will the 40*40*20mm frame and screw pattern line up with my existing 40mm mounting points?

Yes, the 40mm square frame with 20mm thickness uses the industry-standard hole spacing for 40mm fans.
