140 mm Reverse-Blade ARGB Fan

The Lian Li UNI FAN TL 140 mm case fan uses a reverse-blade design to push air through radiators or restricted panels while keeping cabling minimal. Its slide-in daisy-chain system lets up to 10 fans share a single controller port without loose wires. Black frame and addressable RGB lighting suit stealth or themed builds alike.

Builders Who Want Daisy-Chained 140 mm Cooling

This single pack suits enthusiasts adding one fan to an existing UNI FAN TL chain or starting a new cluster of up to four individually addressable units. Buyers who need a controller in the box or who prefer conventional blade direction for unrestricted intake should look at other models.

Reverse-Blade Airflow Direction

The defining specification is the reverse blade orientation, which pulls air through the motor side instead of pushing it out the front. This makes the fan effective on the push side of a radiator or behind dense mesh where standard blades stall.

  • Slide-in daisy-chain links up to 10 fans without extra cables

Questions about this item

Does the single pack include a controller for the ARGB lighting?

The single pack contains one 140mm fan with reverse blades and daisy-chain cables; a controller is not included and must be purchased separately

How many fans can I chain together on one controller port?

Up to 10 fans can be connected to a single controller port using the extension cable

What does the 140mm size mean for airflow in my case?

The 140mm frame moves more air at lower RPM than smaller fans, so it fits 140mm mounts and runs quieter at the same cooling level
