Size: 140mm


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

    • Great fans if bought new, had problems when I purchased used
Size: 140mm Style: SLIN140-R Reverse Single Pack Black
These look great and I have had no problems with thermals. They really were plug and play and the RGB worked immediately and synced with everything else in the case. The only reason I am giving it four stars instead of five is I initially bought these used and it said "Mint" condition, but several fans were very scratched and completely missing cables, and some were not reverse blade despite the box saying they were. I was able to return those used ones and get new ones and then had no problems. The ability to daisy chain also made these super easy to install and made cable management much better. The one recommendation I would make is just be careful if you do buy them used. ... show more
