![]() The front of the box shows the model name of the fan, as well as stating the new frame design that allows the installation of anti-vibration rubber pads. The packaging design is elegant, which should not be a surprise from Noctua. A simple hard cardboard box colored in the signature gray with brown accent on the sides. The NF-P12 redux fans have a very similar package design to the chromax line. In this review, we are taking a look at the new NF-P12 redux fans. This is a nice accessory, which could prove to be quiet useful.ฤก.When Noctua released the latest flagship cooling fan, NF-A12x25, they moved the NF-P12 fans to the more budget-friendly redux lineup. Included in the box, are two mounting brackets and eight anti-vibration mounts. They make it possible for the 120 mm fan to be installed on a 280 mm radiator. They are designed not for the NF-P12 Redux fans, but for the NF-A12x25 fans. Noctua also sent the NA-SFMA1 to us, which are adapters for radiators. Otherwise, on the back of the fan, we have some more information covering the fan model and some electrical specifications. SSO bearings are designed to bring the best of both worlds promising longevity, but to also be quiet. As we have already covered, this ensures that the fans have a MTTF of a 150,000 hours. The SSO bearings are hydrodynamic with a magnet which helps with stabilization. For the most part, sleeve bearings are quieter, but do not last as long as ball bearings. These bearings last much longer than sleeve or ball bearings, both of which have their own advantages and disadvantages as well. The Noctua NF-P12 Redux fans have Noctua's SSO bearing. The specifications seem to be up to par, we will just have to see how they perform on the next page. Lastly, the static pressure measures in at 1.21 mm H2O. ![]() The last version with a maximum RPM of 900, with airflow measuring in at 63.4 m3/h, and acoustical noise a little lower than the others coming in at 12.6 dB(A). The 1300 version has the exact same specifications. Static pressure measures in at 1.68 mm H2O. However, noise emissions are slightly lower as well coming in at 19.8 dB(A). Airflow is a little lower than the 1700 RPM version, measuring in at 92.3 m3/h. For the NF-P12 1300 PWM, we have a max RPM of 1300 and a minimum of 300. Airflow measures in at 120.2 m3/h, while acoustical noise is 25.1 dB(A). The max RPM is 1700, while the minimum is 450. Starting with the Noctua NF-P12 1700 PWM. When it comes to specifications, there are quite a few we need to cover for the four different fans. The picture above and the picture below help you to see how the notches are placed. Noctua has a full page describing in more detail how these extra blades work with the notches. The notches help to redirect how the air is pulled through the impellers. These added blades would cause more noise, but the notches help to reduce noise, as well as increasing efficiency. The addition of the notches along the outer edges of the impellers are required because of the added blades in the fan. The nine closely spaced fan blades ensure that high static pressure can be achieved at much lower RPMs. The Noctua NF-P12 Redux has nine blades, which according to Noctua, are specifically designed for high pressure environments. Just like Noctua's other fans, there are some quality promises to back up the price. Furthermore, the NF-P12 Redux is backed by a MTTF rating of 150,000 hours, as well as a six year warranty. It also features Noctua's Smooth Communication Drive 2, which eliminates torque variations and switching noises, making the fan even quieter. The NF-P12 Redux is optimized for cooling heatsinks or radiators that require high pressure to push air through the fins efficiently. However, this fan still has many of Noctua's more premium fans' features. This adds quite a bit of flexibility to the color scheme, as opposed to some of Noctua's other fans that have a fixed color. These are anti-vibration pads and mounts available in many different colors. The new design of the frame is due to its compatibility with Noctua's NA-SAVP1. The impellers are a darker gray, while the rest of the frame is slightly lighter. For the Redux line to stand out, Noctua has opted to change the colors to gray. Pictured above and for the rest of this page, the Noctua NF-P12 1300 PWM is featured. All four versions of the Noctua NF-P12 Redux fans have the same exterior features, and so I only took a picture of one of them. The Redux line is an updated version of some old favorites, the NF-P12 PWM and NF-P12.
