Time for some Noctua love in the 140mm fan department. Their 120mm fans we saw before, especially the NF-S12A FLX and NF-F12 IPPC 2000 PWM, were generally good performers but they all came at a price that didn’t make them so easy to recommend. Thanks to Hank from Performance PCs, let’s see if the NF-P14s Redux says otherwise.

Let’s begin by taking a look at the specs courtesy the product page:

There are multiple NF-P14 fans in the Redux series of Noctua fans, with options of square frame or round frame (hence the s here), PWM or voltage control, and different max rated RPM. This particular version is a PWM fan rated at 1200 RPM and has a square frame. We see the dimensions of the fan are accordingly 140 x 140 x 25mm, making this a standard 25mm thick fan and thus compatible out of the box with radiators that provide installation screws for such fans. The Redux series is based off older fans, and that is why we don’t have a Redux NF-A14 with newer features such as their SSO2 bearing vs the first gen SSO (self-stabilising oil-pressure) bearing here. I like that Noctua has included not just the max speed and % deviation but also the minimum rated speed with respective % deviation as well. Another key metric here is the inclusion of rated max input current (and hence power) which is the max power draw of a fan and not just what it draws during operation. The high MTBF (presumably at 25 ºC) is also reflective of the excellent 6 year warranty, and Noctua has very good customer support in general irrespective of where you are located from. So far so good here, let’s now take a look at the fan on the next page.
