Manufacturer description

The Lian Li UNI Fan SL-Infinity 120 (UF-SLIN120-1B) is a 120mm ARGB fan for builders who want their cooling to look good and keep the cables tidy. An infinity mirror wraps the whole fan, so the 40 LEDs inside create a layered tunnel effect you can see from any angle, not just straight on. The UNI daisy-chain design connects up to 4 fans in a cluster with one cable. Pin-to-pad contact points join the fans directly, which cuts the usual tangle of fan and RGB leads behind the motherboard tray. The removable keylock and reversible cable module also make it easier to mount on a radiator without…

Frequently Asked Questions

Does the Lian Li UNI Fan SL-Infinity 120 come with a controller?

No. This UF-SLIN120-1B single pack is sold without a controller. To run the daisy-chain and lighting effects, you'll need a compatible Lian Li UNI controller or hub. Check the product listing to confirm which controllers it works with.

How many SL-Infinity fans can I connect with one cable?

Up to 4 fans per cluster. The fans link through pin-to-pad contact points, so a single cable runs the whole group.

Can I mount the SL-Infinity 120 on a radiator?

Yes. The keylock is removable and the cable module is reversible, both meant to improve fit around radiator fittings. It's a 120mm fan, so match it to 120mm radiator mounts.

Will the fan stop spinning when my PC is idle?

Yes. Its start/stop mode stops the fan completely when your CPU or GPU runs below the temperature set in your system.
