Noctua has combined a lot of features to bring us the NF-A12x25. It was built around the concept that the blade tips would run about 0.5 mm from the frame – a tight clearance intended to deliver more static pressure and lose less airflow through the blowback. To pull this off the OEM used a whole box of tricks: they made it from a more rigid plastic called Sterrox, used reinforced bearings, stiffened corners, and tightly swept blades.
When one places a gasket on the fan before putting the fan on a rad, it does two things. First, it seals the gap between the fan and the rad, forcing more air through the rad. This is aided by the tight clearance between the blades and the frame. The gasket also reduces the vibrations produced by the fan. So one has a high-performing quiet fan. Add to this Noctua’s six-year guarantee and one has quite a fan.
If one uses an NA-SFMA1 they could put this 120 mm fan on a 140 mm rad. This combo makes a surprisingly good pseudo 140 mm rad fan, and quieter than most.
"The key to this fan’s performance is that throughout its operational range it is quieter than most competing fans. As usual, these fans from Noctua are a bit on the high side, price wise, but one pays for quality and Noctua delivers." (Ed Hume, overclockers.com)
