Features

  • An all-around infinity mirror design creates a multi-layer effect visible from any angle emphasizing the 40 LEDs in each fan.
  • When installed as an intake fan with the reverse blade this increases the airflow and lowers the wind noise.
  • The use of one cable to connect up to 4 fans in a cluster and pin-to-pad contact point ensures simple cable management.
  • The removable keylock and reversible cable module allows for improved compatibility with radiator fittings.
  • The fan blades and the fan frame inner edges can be customized with individual lighting modes or choose from the pre-set combined lighting effects options. Embedded magnetic Fluid Dynamic Bearing provides stability, durability, and longevity.
  • Features a start/ stop mode to completely stop the fan when the CPU or GPU is running below the system's set temperature.

Amazing looking fans that are quite and well built. I love the aesthetic of the fan and the options to adjust how they look and what color they run at thru the lian li program is top notch.

    • Works well
Size: 140mm Style: SLIN140-R Reverse Single Pack Black
Used as a bottom of the computer case intake fan in a Thermal Take Tower 300 (mounted just above the power supply). Chose the reverse blade version for a cleaner look inside the case that avoids showing the “ugly” side of the fan where the wires are usually crammed into narrow channels. The sides of the fan have infinity mirrors which match the RGB of the fan blades and give it a unique look. May someday replace the 3 120mm fans that came with my AIO CPU cooler with these fans, but would be mainly for the aesthetic. Quality of the fan itself is great and the customization of the cables and mounting are great options. ... show more

    • Stunning aesthetics for a high-end Threadripper build!
Size: 140mm Style: SLIN140-R Reverse Single Pack Black
I added this Lian Li SL-Infinity 140mm Reverse Blade to my Phanteks NV7 build featuring a Threadripper 7960X. I’m using it for exhaust, and it looks absolutely amazing. The main reason I went with the Reverse Blade is for the aesthetics you get to see the beautiful infinity mirror and the "clean" side of the fan without the bracket or motor cage showing. The daisy-chain system made cable management in such a large case much easier, and the ARGB lighting is incredibly vibrant. Even though I’m pushing a high-performance CPU, this fan moves a good amount of air while staying very quiet. If you are building a showcase PC and want the best-looking fans on the market, these are worth every penny. ... show more

    • Look amazing and aren't too loud
Size: 140mm Style: SLIN140-R Reverse Single Pack Black
The fans are super easy to connect minus if you need to turn the cable around, the plastic clip part can potentially get stuck and you feel like you are going to break it but otherwise they are amazing for daisy-chaining and you won't need a ton of cables. the software to connect them sadly doesn't kick in till your computer is fully on so your set colors won't show right away, enjoy the rainbows. ... show more

I installed these fans into my new case and were shocked as how cool the work. They were very easy to install since they attach to each other so I only need three connectors and the app allows you to setup all these different patterns. They don't sound loud and seem to cool my gaming PC very good.
