120 mm USB Case Fan

The SXDOOL 12025router is a 120 mm case fan powered directly from a USB port. It targets builders who need simple spot cooling for a computer case, router, TV box or similar small enclosure without wiring into a motherboard header.

USB Power Limit

Because the fan draws 5 V from a standard USB connection, its maximum speed and airflow are capped by the port’s current rating. It cannot reach the RPM or static pressure of 12 V PWM fans, so it suits low-restriction airflow rather than dense radiator or heatsink stacks.

120 × 25 mm Plastic Frame

The 120 mm diameter and 25 mm thickness fit common 120 mm mounting holes and include a protective net and screws. The plastic frame keeps weight low, but the USB power ceiling means the fan runs out of headroom when pushed against high-impedance filters or tight grilles.

Questions about this item

Which size of this SXDOOL fan should I pick for a standard 120 mm case mount?

The 12025router model measures 120x120x25 mm, matching the common 120 mm mounting pattern used in most computer cases.

What does the USB power interface mean for everyday use inside a PC?

It draws 5 V directly from a motherboard USB header or any USB port, so no separate 12 V fan header or molex adapter is required.

How does the USB connection limit the fan's speed control compared to a PWM header?

The USB link supplies fixed 5 V power only; it lacks a PWM signal wire, so the fan runs at a constant speed and cannot be regulated by the motherboard.
