SXDOOL

SXDOOL D9225B12H 92mm PWM Case Fan 12V 0.2A 900-3150 RPM Double Ball

SKU CH-6289-N9NVX

92 mm PWM case fan with double-ball bearing, 900–3150 RPM speed range and 4-pin motherboard control

  • TypeCase Fan
  • PWM speed control adjusts fan speed from 900 to 3150 rpm
  • Double ball bearing design extends operational lifespan
  • 12 V DC power with 0.20 A current draw
  • Compact 92 mm square frame fits tight chassis spaces
  • Four-pin connector enables motherboard temperature regulation

Compact 92 mm PWM case fan

This SXDOOL D9225B12H case fan fits 92 mm mounting holes with a 25 mm frame depth. It runs on 12 V DC and draws 0.20 A at full speed, dropping to 0.035 A at minimum. The four-pin PWM connector allows motherboard speed control between 900 and 3150 RPM. Double ball bearings support continuous operation in servers or workstations.

Suits small-form-factor builds and server refreshes

Builders working with 92 mm fan mounts and a 4-pin PWM header will find this a direct fit. Systems that demand higher static pressure or larger frame sizes will need a different fan. Buyers without a PWM header cannot use the automatic speed control feature.

Double ball bearing with 900-3150 RPM range

The double ball bearing is the specification that determines long-term reliability and noise profile at varying speeds. It enables the wide 900 to 3150 RPM range while maintaining consistent performance. If your application requires sleeve or fluid dynamic bearings instead, this model is not the correct choice.

Questions about this item

What comes in the box with the D9225B12H and what must I buy separately?

The fan itself is supplied; the 4-pin PWM connector plugs directly into a motherboard header so no extra cable or adapter is required.

How do I choose between the 900 RPM low end and the 3150 RPM high end of the D9225B12H?

The fan runs from 900 to 3150 RPM ±5% under PWM control; select a speed in the BIOS or fan software that matches your cooling target and noise tolerance.

What does the 3150 RPM figure mean once the D9225B12H is installed in my case?

At full PWM duty the fan spins at 3150 RPM ±5%, moving the maximum airflow the 92 × 92 × 25 mm frame can deliver through a heatsink or case vent.
