Lian-Li for a clean look and optimal control

If you got a build that needs that Ferrari look, it's gotta be Lian-Li! These work great with the wireless hub controller. The software is good and you can customize the screen in many many ways, and it picks up the proper measurements/temps accordingly. You will still need to use a fan power cable, but one cable vs 2+ is a great thing for clean builds. It's higher on the price scale, but you're buying one of the best looking fans on the market. There is no infinity version, so plan accordingly. Also there is no RGB for the fins, but I support that design decision.
