Noctua NF-S12B FLX 120mm Fan Review - Pictures



The Noctua NF-S12B FLX comes in very typical packaging from Noctua, sporting their standard brown/blue color scheme, with a very simple layout with plenty of features, information, and specifications.



Here are the contents of that fan's box laid out, which includes four (4) standard fan mounting screws, four (4) rubber anti-vibration fan mounts, the two fan speed adjustment cables, a 3-pin to 4-pin molex adapter, and the fan itself.  I'm not a particular fan of the color scheme, but I can put that aside, and that should only really matter for those with a very particular color/lighting scheme they want to fulfill.


Here is a closer look at the fan itself.  On the left you can see the very nicely sleeves cable leading from the fan, which has plenty of length to allow you some options with your cable management to the fan, or allowing it to reach the front of your case to a fan controller.  You can also see the very aggressively oriented blades at a high angle of attack which are also rather large in size.  Each blade takes a large "bite" out of the air, and thus allows it to push alot of air, even at lower RPMs.  You may also notice the curvature of the blades as well as the beveled tip, both of which allow for vortex reduction which drastically reduces noise levels.


Here is a closeup of the beveled ends of the fan, which help reduce noise while adding to the airflow and static pressure created by the blades.  This is really what separates this latest generation of Noctua's Ultra-Quiet fans.

Now, lets see if this Ultra-Quiet fan can also live up to its claims!
