Modular 120 mm ARGB case fan
The DOCTOR METAL UF-SL120-1B is a single 120 mm fan built for PC builders who want clean cable routing through snap-together modular daisy-chaining. It targets enthusiasts assembling custom loops or air-cooled rigs where reducing wire clutter matters more than an all-in-one kit. Buyers who need a standalone fan with its own controller in the box should look elsewhere.
Daisy-chain design removes individual fan wires
Each unit connects to its neighbour through a contact-pad interface, so only the first fan in a chain plugs into a separate controller. The package supplies three mounting frames that let multiple fans share screws, cutting installation time. Without the required controller — sold separately — the fan and its 32 addressable LEDs cannot be powered or synchronised via L-CONNECT software or motherboard headers.
Airflow and noise envelope for typical case cooling
At 800–1900 RPM the fan moves 55–60 CFM with a peak static pressure of 2.54 mm H₂O, enough for standard mesh-front cases or mid-density radiators. Noise stays between 17 and 31 dB across the speed range. Builds demanding higher static pressure for thick radiators or restrictive filters will exceed the comfortable operating window of this model.

Questions about this item
How often should I expect to replace the fluid circulative bearing in the UF-SL120-1B?
The fluid circulative bearing is sealed for the fan's lifetime and does not require scheduled replacement under normal operation.
What limits sustained performance first on this 120 mm fan — airflow or static pressure?
At maximum speed the fan delivers 58.54 CFM airflow and 2.54 mm H₂O static pressure; the lower pressure figure typically becomes the bottleneck in restrictive radiators or dense meshes.
How loud and hot does the fan get when running at 1900 RPM all day?
At 1900 RPM the noise reaches 31 dB; the motor draws 12 V and the LEDs draw 5 V, with no separate thermal rating provided for continuous duty.
