The sound pressure meter is a Tenma 72-942. SPL was adjusted to 1 meter by subtracting 20 dB. To measure noise levels that were softer, the Sound Pressure Level (SPL) was measured 10 cm from each fan. The ambient noise for this set of testing is 31 dBA, sounding like the silent basement that it is.
The standard proxy for what you can hear is the Sound Pressure Level (SPL), measured in decibels with a type A-weighting (dBA).

The fans were placed in a test stand, where their free air RPM was observed and their noise was assessed. As is fairly obvious, the blades on the successor fan are highly cranked. The tips of the fans are closer than contemporary fans, even if they are not as tight as the NF-A12x25 that replaced them. Two Walls at P12 Corner - Note Four Directions The corners of the NF-P12 look different because it uses a tooling that opens towards four sides and this is actually the case with most of our fans.” The engineering challenges were different for the A12x25, which accounts for the change. He said, “I had to check with our engineers. Since I just noted that the A12x25 frames had corners that pointed in two directions, I asked the Noctua marketing person about this. The twin wall pairs point in four directions. The frames have dual walls flanking the screw paths at each corner of the redux fans.
They are available in five colors (black, red, blue, white, green and yellow) and designed to fit in users build themes. In fact, that was a design consideration, with Noctua saying the fan supports their chromax line NA-SAVP1 anti-vibration pads. You can see how the corners have changed to corners that now support anti-vibration pads. In fact, we can compare the old premium fan with one from the redux line. This explains why this fan sold well enough to stay in production and become four redux fans. They are designed to change the sound the blades make as they cut through the air, making them more ear-friendly. One also cannot miss those trailing edge notches. The coloration is not what we are used to in their premium fans in brown and tan, but we see “redux gray.” The blades are not as bent as what we are used to - but really that is not objectionable since there were fans with curved blades when the P12 first came out. One of the first things we can see is the blades are close together making it look like their static pressure was definitely a consideration. When we look at the P12 redux we notice a few things. The long power cable and a package of fan screws are under the plastic case. The next picture shows you the plastic enclosure sheltering the fan from knocks and crunches in shipping. The fan is packaged in a cardboard box keeping with Noctua’s theme of simplicity. Pressure-optimized Nine Blade Design with Vortex-Control Notches

One unique feature of the PWM fans is the use of a silent circuit that makes the once-common clicking sound PWM fans make a thing of the past.įinally, they remind you that they produce accessories that can be purchased to go with this fan: “Users can choose from Noctua’s wide range of optional accessories such as anti-vibration mounts, Low-Noise-Adaptors, y-cables, 3-pin to 4-pin adapters or extension cables to upgrade redux edition fans according to their individual needs.” Specifications FAN Specification These notches spread the fan’s noise emissions over a wider range of frequencies reducing audible noise making them easier on the ear. Their design also includes vortex control notches which split up the trailing edge vortices.

The P12 series has been manufactured with high-pressure applications in mind with Noctua’s use of nine, tightly spaced “pressure optimized” blades on the impeller. Noctua maintains product pages to highlight the features of the various P12 models: How do the fans function in various environments? We will examine the performance of all four fans and see how it adds up.
The P12 sold well enough to remain a premium fan all these years and sells well enough to be made into four redux fans. The big difference between them is in the price with the redux saving 33% over the fully accessorized NF-P12. The NF-P12 redux line will include four SKUs – two DC controlled fans at 900 at 1300 RPM and two PWM fans at 13 RPM. The redux line of fans is intended to have the same performance as the premium line, but sold in an OEM manner (without accessories) to keep costs down. Today we have an opportunity to look at one of Noctua’s fans that made the jump from their premium line down to the redux line in the NF-P12 redux.
