120 mm ARGB PWM case fan

The SUIUBUY Su-LL120-B is a 120 mm case fan with addressable RGB lighting and a PWM motor. It moves up to 58.54 CFM of air at a maximum static pressure of 2.54 mm H₂O. Speed ranges from 800 to 1900 RPM while noise stays between 17 and 31 dBA. A fluid dynamic bearing supports long-term operation.

Requires separate ARGB controller

This fan suits builders who already own a compatible 5 V ARGB controller and want to add a single black unit to an existing daisy-chain. It is not for buyers who need a controller included in the box or who prefer a plug-and-play kit with hub and remote. The 3.5 W motor draws 0.18 A at 12 V; the LEDs draw 0.6 A at 5 V.

5 V ARGB 3-pin + 12 V PWM 4-pin

The decisive specification is the dual-cable design: a 3-pin 5 V ARGB connector for lighting and a 4-pin PWM connector for speed control. Both must connect to matching motherboard headers or a dedicated controller. Without a 5 V ARGB header the lighting cannot be addressed, and without a 4-pin PWM header speed regulation is not possible.

Questions about this item

Should I pick the single-fan pack or a multi-pack for my build?

The Su-LL120-B is sold as a one-fan pack without a controller; add more fans of the same model if you need additional airflow and already own or plan to buy a compatible ARGB controller.

What does the 58.54 CFM maximum airflow mean once the fan is installed in a case?

At full speed the fan moves up to 58.54 CFM with 2.54 mm H₂O static pressure, so it can push air through mesh panels or radiator fins while staying within the 17–31 dBA noise range.

How does the 5 V ARGB and 12 V PWM daisy-chain interface limit what I can connect?

Each fan draws 0.18 A on the 12 V PWM line and 0.6 A on the 5 V ARGB line; the motherboard or controller header amp rating caps how many fans you can chain before voltage drop or current limits are reached.
