💡 How to pick case fans
What to look for:
  • 120mm most common, 140mm moves more air quieter
  • Higher CFM = more airflow, higher dBA = more noise
  • Static pressure fans for radiators, airflow fans for cases
💰 Two intake + one exhaust is a solid baseline for positive pressure

★★★★★Positively Stunning

★★★★★Very good airflow and RGB options
This fan is incredibly easy to set up and the daisy chaining feature makes cable management very bearable for having to set up multiple rgb fans. The lian li software used to control the fans let you set up any color scheme to your liking with ease. These are the best looking fans on the market right now to me and I’m very happy with this product.

★★★★★Ultimate in RGB fans.
Beautiful fans from both sides with stunning RGB lighting and infinity mirrors. Super quiet and so easy to install with snap together connections - three fans need only one cable.

★★★★★To infinity and beyond…
These fans are awesome if you like RGB. The L Connect software works great at customizing your build. I use these as my exhaust fans up top. I am very pleased at how cool and quiet they keep my PC. I connect the 2 140mm fans to a Lian Li control box that came with the 120mm 3 pack. 10/10
