💡 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

★★★★★Quiet, looks great and keeps my PC very cool
After much research, I decided on a mostly Lian Li build. Their interlocking infinity fans just looked too cool to pass up and the allure of just snapping them together and not having more wires made them a no-brainer. They feel high quality, look incredible and are very quiet. Like so quiet I almost can't hear anything, even under heavy gaming load. I think the ARGB controller leaves a little to be desired, but the fans themselves are nearly perfect. They also come with little screen protectors if you are worried about scratching the mirrored surfaces on the sides. I've been using them for a while now and still can't stop looking at them.

★★★★★Incredible fans
Great looks, airflow, and noise level. The daisy chain feature makes installation a breeze.

★★★★★Quiet and pretty
These are the perfect fans to complete the intake and still have the LEDs show. They daisy chain, making cable running much easier than some other fans. The LEDs are bright and programmable with the Lian-Li software. Decent value, and quiet.
