Modular 120 mm ARGB Fan

The Lian Li UNI Fan SL120 V2 is a single 120 mm case fan with a 28 mm thick frame, fluid dynamic bearing and addressable RGB lighting. Its interlocking design allows up to six fans to be linked in two clusters through one controller port. A plug-in cable module sits flush with the frame to ease cable routing.

Builders who want daisy-chained RGB cooling

Suits system builders who want synchronized lighting across multiple fans and simpler cable management using the proprietary UNI Hub controller. Not suited for users who lack the proprietary controller or prefer standard PWM fans without daisy-chaining.

28 mm frame thickness

The 28 mm thick frame delivers a 10 % airflow improvement over the previous version while balancing static pressure. This dimension decides whether the fan clears your radiator fittings and side-panel clearance.

Questions about this item

Does the single pack include the UNI HUB controller or do I need to buy it separately?

The single pack contains one 120 mm fan with an 18 cm extension cable and a plug-in power cable module; the UNI HUB controller is not included and must be purchased separately.

Is the 28 mm thick SL120 V2 the right choice if I want the improved airflow version?

Yes, the V2 uses a 28 mm frame that delivers a 10% airflow optimisation over the V1 while keeping the same 120 mm diameter.

What does the 10% airflow optimisation mean for temperatures inside my case?

The thicker frame moves more air at the same noise level, so CPU and GPU temperatures drop a few degrees under load compared with the thinner V1 design.
