80mm PWM hydraulic case fan

The SXDOOL 80mm case fan uses a hydraulic bearing and a 4-pin PWM connector for automatic speed control. It fits standard 80 x 80 x 25 mm mounting points and runs on 12 V DC power. The black, non-LED frame keeps the appearance neutral inside any chassis.

Suited for compact builds needing variable airflow

This fan serves small-form-factor cases or CPU coolers that require an 80 mm frame with PWM regulation. Buyers who need larger diameters, RGB lighting or higher static pressure for dense radiators should look at other models.

Sustained operation at controlled speeds

The hydraulic bearing maintains consistent performance during continuous use while PWM adjusts the motor between 1300 and 4000 RPM based on temperature. The 0.40 A current draw stays steady so the fan delivers reliable cooling without sudden speed spikes.

Questions about this item

What motherboard header is required to run the 4-pin PWM control on this 80mm fan?

A standard 4-pin PWM fan header on the motherboard is needed; the fan draws 0.40 A at 12 V.

Will the hydraulic bearing maintain the 1300 RPM minimum speed if I keep my older 3-pin voltage-controlled headers?

No, the 1300 RPM floor is only reached through PWM signalling; on a 3-pin header the fan will run at full voltage and stay near its 4000 RPM maximum.

How can I confirm the fan is responding to the PWM curve after installation?

Use BIOS or monitoring software to watch the RPM reading change smoothly between 1300 and 4000 RPM as the temperature target moves.
