Lian Li UNI FAN RTL120 Single Fan

The Lian Li UNI FAN RTL120 is a 120mm ARGB case fan with a 28mm thick frame and reverse blade design. It uses a slide-in daisy-chain mechanism that connects directly to adjacent fans without extra cables. The unit requires a separate UNI FAN controller for power and L-Connect 3 software control. This single pack suits builders adding to an existing UNI FAN ecosystem.

Suits daisy-chain RGB builders needing one reverse

This fan fits builders expanding a current UNI FAN TL or SL-Infinity cluster where a reverse airflow blade is required. It supports clusters of up to 4 fans per channel and up to 10 fans per controller port using extension cables. Builders without a compatible UNI FAN controller cannot operate this fan. Buyers needing a controller in the box should choose a multi-pack kit instead.

Reverse blade 120mm fan with daisy-chain ARGB

The defining specification is the reverse blade orientation combined with the slide-in daisy-chain connector. This determines airflow direction through the radiator or case panel and dictates physical compatibility with other UNI FAN TL series units. The 28mm thickness and dual-zone infinity mirror lighting are fixed physical traits that must match the existing cluster layout.

Questions about this item

What does the 28mm thickness mean for fitting this fan in my case?

The 28mm depth requires more clearance than standard fans, so check that your case or radiator mounting area can accommodate the extra size before installation.

How does the slide-in daisy-chain connection work for linking multiple fans?

The male and female ends slide together to chain up to 10 fans per controller port, forming clusters of up to 4 fans each for individual RPM and lighting control.

What mounting dimensions does this 120mm fan use?

It uses standard 120mm mounting hole spacing, so it fits any case or radiator designed for 120mm fans.
