SXDOOL SXD12025B12H 120mm 3200RPM 94.5CFM 38.5dBA Dual Ball Bearing Case Fan

Target devices and control

This 120 mm case fan is designed to cool consoles, routers, receivers and similar electronics. A supplied speed controller lets the user adjust airflow to match the noise environment. Dual ball bearings rated for 50000 hours allow horizontal or vertical mounting. The unit ships with a metal finger guard and a 7.7 ft power lead.

Thermals noise and power

At the maximum 3200 RPM the fan moves 94.5 CFM while producing 38.5 dBA. The controller draws AC 100-240 V and outputs DC 3-12 V at 2 A, so the fan can run from a wall outlet. Over-voltage, over-current and short-circuit protection are built into the adapter. Speed can be lowered to reduce both airflow and sound.

Deciding specification

The critical figure is the 38.5 dBA noise level at full speed; buyers who need quieter operation should look elsewhere. The 12 V DC input and 5.5 mm × 2.1 mm barrel jack limit compatibility to devices that accept that connector. No LED lighting is present, so the fan suits stealth builds only.
