Compact 90 mm chassis fan

The SXDOOL 90 mm case fan runs on 12 V and draws 0.16 A through a three-pin connector. It spins at roughly 2500 RPM while producing 19 dB(A) of noise, making it a quiet choice for tight builds. The red, black and yellow leads provide power, ground and a speed signal for monitoring. It fits 90 mm or 92 mm mounting holes with a 25 mm frame depth.

Suited for low-noise intake or exhaust

This fan suits builders who need a slender 90 mm unit for case ventilation, power-supply replacement or small-form-factor chassis where space is limited. The fixed-voltage three-pin design means speed scales with voltage rather than a PWM signal. It is not for systems that require four-pin PWM control or higher airflow than 2500 RPM can deliver.

Three-pin voltage-controlled connector

The single specification that decides fit is the three-pin 12 V connector, which only supports voltage-based speed regulation. Motherboards or fan controllers without a three-pin header cannot drive this fan directly. Verify the header type before purchase.

Questions about this item

Does the fan ship with mounting screws or do I need to buy them separately?

The listing only describes the fan itself — a 90 mm unit with a 3-pin connector — so mounting screws are not included and must be sourced separately.

Should I choose the 90 mm or 92 mm frame size for my case?

The product is specified as 90×90×25 mm and also noted as compatible with 92×92×25 mm mounting holes, so either frame size will fit the same fan.

How loud is 19 dB(A) at 2500 RPM inside a typical PC case?

At 19 dB(A) the fan is rated as very quiet; at 2500 RPM it moves enough air for general chassis cooling while remaining barely audible in most builds.
