USB-Powered 120mm Case Fan

The SXDOOL 12025L05R is a 120mm case fan that draws power from any standard USB 1.1 or 2.0 port. An inline governor lets you adjust speed without software, making it suited for DIY cooling projects, router enclosures or supplemental airflow in a PC build.

Airflow Capacity and Limits

At full speed the fan moves roughly 78 CFM while spinning at 1200 RPM, with a rated ceiling below 1600 RPM. The hydraulic bearing and 5 V, 0.2 A design keep output steady for typical case or device cooling, though the 5 W power limit means it cannot replace high-static-pressure coolers on heavy thermal loads.

Thermals, Noise and Power Draw

Rated noise sits at 15 dBA, so the fan stays quiet even when the governor is opened up. Power draw is a modest 5 W from a 5 V USB source, and the 20 cm cable reaches most internal headers or external power banks. The hydraulic bearing is rated for 30000 hours of continuous operation.

Questions about this item

Will the SXDOOL 12025L05R 120mm USB fan work from the same 5V USB 1.1/2.0 ports on my older motherboard?

Yes, the fan draws 0.2 A at 5 V from any USB 1.1 or 2.0 port, so it runs on legacy motherboard headers without extra power.

How can I confirm the SXDOOL 12025L05R is running correctly once I plug it in?

With the governor attached, the fan spins up to 1200 RPM and delivers 78 CFM while staying at 15 dBA, so you can hear and feel steady airflow.

Does the SXDOOL 12025L05R package include the speed governor and cable, or must I buy them separately?

The box contains the 120×120×25 mm hydraulic-bearing fan, a 20 cm USB cable and the inline governor; no extra parts are required.
