Compact 90 mm PWM case fan

The SXDOOL EF92251S1-Q010-S9A is a 90 mm square frame fan measuring 25 mm thick. It runs on 12 V DC and draws 3.83 W through a standard 4-pin PWM connector for automatic speed control.

Suited to tight chassis and targeted airflow

Builders fitting a 90 mm mount in a small-form-factor case or using the fan for spot cooling on a heatsink will match the 9025 footprint. Anyone needing a different frame depth, a 3-pin voltage-controlled header, or a larger mounting pattern should choose another model.

90 mm frame with 4-pin PWM control

The 90 mm by 90 mm by 25 mm dimensions and 4-pin PWM interface are the single specification that decides fit. Verify the case or heatsink accepts a 9025 fan and that the motherboard or controller provides a 4-pin PWM header before purchasing.

Questions about this item

Does my motherboard need a 4-pin PWM header to run this 90 mm fan?

Yes, the fan uses a 4-pin connector and requires a 4-pin PWM header for speed control.

Will this 90x90x25 mm fan fit in the same mounting holes as my old 9025 fan?

Yes, the 90 mm square frame and 25 mm thickness match the standard 9025 mounting pattern.

How can I confirm the fan is spinning at the correct PWM duty cycle after installation?

Check the RPM reading in BIOS or monitoring software; it should vary smoothly with the PWM signal sent to the 4-pin header.
