  • Compact 40 x 40 x 28 mm frame fits tight chassis spaces
  • 3 CFM airflow delivers strong air movement through restricted paths

SXDOOL 40mm 22000 RPM PWM Fan

The SXDOOL pf40281bx-d090-s99 is a 40 mm square case fan that spins at 22000 RPM from a 12 V supply. It targets builders who need concentrated airflow in tight spaces such as 1U servers, small-form-factor workstations or GPU cooler replacements.

Double-ball bearing four-wire design

Double-ball bearings support the high rotational speed while the four-wire lead delivers PWM speed control and tachometer feedback. The 40 × 40 × 28 mm frame fits standard 4028 mounting holes so the fan can be swapped directly into existing brackets without modification.

Replaces lower-speed 40 mm fans

This unit supersedes slower 40 mm fans when 31.3 CFM and 62 dBA are acceptable trade-offs for maximum heat removal. The upgrade is worthwhile only when the chassis can tolerate the acoustic output and the power budget covers 10.80 W per fan.

이 상품에 대한 질문

What does the 4-wire PWM connection on the pf40281bx-d090-s99 control?

The 4-wire lead provides PWM temperature control and speed measurement, letting the motherboard adjust the fan up to 22000 RPM based on system thermals.

Will the 40 mm by 28 mm frame fit my 4028 mounting holes?

Yes, the fan measures 40 x 40 x 28 mm, matching the standard 4028 form factor for 40 mm mounting patterns.

How do I connect the 4-wire lead so the speed signal works?

Plug the 4-pin connector into a PWM header on the motherboard; the fourth wire carries the tachometer signal back to the BIOS for speed monitoring.
