What this product is

The SXDOOL SXD12032B12H is a 120mm centrifugal blower fan rated at 3400 RPM with 40 CFM airflow and 54 dBA noise. It uses dual ball bearings rated for 50000 hours and includes a stepless speed controller with a 100-240V AC adapter outputting DC 3-12V at 2A via a 5.5x2.1mm connector. The 120x120x32mm black frame draws air from the bottom and exhausts it rearward for tight-clearance cooling.

What to check before ordering

Verify that your device accepts a DC input within the 3-12V range and uses a 5.5x2.1mm female jack. Ensure the 120mm square footprint and 32mm thickness fit your enclosure, and confirm the rear exhaust path is unobstructed. The included US-plug adapter operates on 100-240V mains, so no separate transformer is needed for most regions.

Who this suits and who should look elsewhere

Builders cooling AV cabinets, network gear, game consoles or small grow tents will benefit from the focused rear exhaust and adjustable speed. Buyers needing standard case airflow, PWM motherboard control, silent operation below 54 dBA, or higher static pressure for dense radiators should consider other fan types.

Questions about this item

Does the blower come with a power adapter and speed controller, or do I need to buy them separately?

The package includes a 100-240 V AC adapter with US plug and a built-in 3-12 V 2 A speed controller, so no separate purchase is required.

Should I pick the 3400 RPM version or a lower-speed model for a quiet home-theater cabinet?

Only the 3400±10 % RPM model is offered; the included controller lets you reduce voltage from 12 V down to 3 V to lower speed and noise as needed.

What does the 40 CFM airflow figure mean when the fan is installed in a tight AV rack?

At full 12 V the blower delivers 40 CFM; in a restricted cabinet the actual flow will be lower, but the centrifugal design still pushes air through tight clearances.
