Style: SLIN140-R Reverse Single Pack Black


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.

  • 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

  • If you want great fan that is amazing to look at to then go no further!
Size: 140mm Style: SLIN140-R Reverse Single Pack Black
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. Have owned for several months and no issues they work amazing will only be using lian li products from now on when I can! ... show more

  • The "Aesthetics Perfectionist" Review (Best for high-end builds)
Size: 140mm Style: SLIN140-R Reverse Single Pack Black
If you care about how your PC looks, these are a game changer. I used these as intake fans on the bottom and side of my case. With normal fans, you would be staring at the ugly plastic frame and sticker on the back. With these "Reverse Blade" versions, you get the beautiful infinity mirror front and proper intake airflow. The daisy-chain mechanism is brilliant—only one cable for a cluster of three fans makes cable management incredibly clean. The RGB is bright, smooth, and the infinity effect on the sides is mesmerizing. They are pricey, but for a showpiece build, they are absolutely worth it. Pros: • Solves the "intake fan looks ugly" problem. • Infinity mirror effect is stunning. • Easy daisy-chain installation (less cable clutter). Cons: • Expensive per fan. • You need to buy a controller separately if you don't have a 3-pack of the standard fans. ... show more

  • Make sure you get an RGB Controller and Fan Hub
Size: 140mm Style: SLIN140-R Reverse Single Pack Black
Does a good job at keeping my system cool while staying somewhat silent. With my headphones in they are not audible. Under load, my 9800X3D and 5070 Ti stay below 70C. Even though Lian Li's O11 Dynamic Evo RGB Case says it supports up to 140MM fans on the side, these were an extremely tight fit. I was able to fit all 3, but I couldn't screw in the 2 top and bottom screws. For some reason, you can no longer buy the controller for the Reverse Blade fans, so I had to buy an RGB controller and fan hub. ... 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

  • Fans look great, software is awful, support is somehow worse
Size: 140mm Style: SLIN140-R Reverse Single Pack Black
cant control the RGB in full unless you use their application, but when their application is running my PC doesnt restart properly. I am not alone in having this issue if you do a web search. reached out to support about it to see if there is any solution and they closed my ticket without offering any help and wont respond to my emails asking to re-open the ticket. ... show more
