Noctua NH-L9i Low Profile CPU Cooler Review

Rating: 8.0.

Space constraints and component clearance can always present a major headache for Small Form Factor and mini-ITX users who want to improve their CPU cooling performance. Can Noctua's minute NH-L9i CPU cooler help to address these issues?

Measuring in at just 95 x 95 x 37mm, the Noctua NH-L9i is best suited to confined environments where space constraints can pose a major issue, such as inside a Small Form Factor case or mounted on a mini-ITX motherboard. Not just happy with usable dimensions, Noctua aims to offer SFF users a worthwhile cooling upgrade with the NH-L9i's 2500 RPM fan and 24mm, densely-packed fin array.

In the NH-L9i, has Noctua designed a cooler which proves that bigger isn't always better?
