Noctua NF-B9 92mm Case Fan Review
Case fans come in a wide variety of sizes, with the most popular ones being 80mm and 120mm. But a somewhat less common size is 92mm, which is in-between the two. Today we’ll take a look at Noctua’s latest fan offering, the Noctua NF-B9 92mm Case Fan. Will this middle child prove to offer the best of both? Read on to find out.

The Noctua NF-B9 92mm fan arrived in a colorful package in the colorful Noctua color scheme, with a clear window displaying the fan. The back of the package describes some of the unique features of the fan and the specifications. Also, the package also opens up to reveal even more test data and technical information about the fan.

Opening up the package, the fan and its associated accessories are found to be well-secured in a customized plastic form. Along with the fan itself, the package comes with four vibration compensators, a 3:4 pin adaptor, a low-noise and an ultra-low-noise adaptor, and a set of regular fan screws.

The fan itself has that trademark Noctua color-scheme, with a peach-colored housing and maroon-colored blade, which I’ve now come to expect from Noctua. Looking closely at the fan, a couple of things to notice are the beveled blade tips and the odd “notches” in each blade (Noctua calls them Vortex Control Notches). These two design features are a couple of things that set apart the NF-B9 from other fans on the market. Given the amount of research and engineering data that Noctua has to back up their fans, it’s pretty clear to see why they are the leader in this industry.
