Noctua has been known for years to be one of the best, if not, the best coolers out for custom PC builders. They are the go to for premium coolers. The L9-i is great for SFFPC builders especially for the new DAN Case A4-SFX. This cooler is a perfect match. The cooler is also quiet and has a unique color scheme that is the Noctua signature. It sort of a brown and beige color. Some people don’t like it, but I love it and it makes the Noctua different from all the other coolers out there. Check out the unboxing video below!
