Noctua NF-B9 Review
 

We’ve seen a collection of various Noctua fans conforming to the standards of 80mm and 120mm, but nothing in the lesser-used 92mm size.

Fortunately, 92mm fan mounts can now use bevelled blade tips and vortex control notches, but more importantly, have a MULNAZ PC. Lets have a look whether it lives up to our previous experiences with Noctua blowers.
