This is the highest speed 140mm fan I currently have in my possession and credit to Noctua for having brought high speed fans like this to the retail market intentionally or otherwise. You see, the industrialPPC lineup was never really intended for case/radiator cooling in the PC DIY market but thanks to Noctua’s good retail distribution channel and these offering a more universally appealing color scheme over the standard retail offerings, the IPPC fans ended up very popular- especially in North America. It just so happens that this is the third NF-A14 fan tested out here, and the previous two slower speed versions were very impressive. I am really eager then to see how this 3000 RPM version ends up doing, especially at the higher end. Thanks to Performance PCs for providing a test sample.
Let’s begin by taking a look at the specs courtesy the product page:
This is a higher speed version of the NF-A14 IPPC-2000 PWM and as such shares a lot with it. It utilizes a square frame with standard 25mm thickness for 140 x 140 x 25mm dimensions making it compatible out of the box with most 140mm size radiators. Unlike the 2000 RPM version, there is no 3 pin voltage control option here so PWM is all you got- which is just fine with me. The fan is rated at 3000 RPM (+/- 10%) and has an advertised minimum speed of 800 RPM (+/- 20%). As with all high speed fans, there is a near exponential increase in power draw going from 2000 to 3000 RPM here with this fan being allocated a max input power draw of 6.6 W (which includes start up boost, and is the max value to consider here). Aside from that, the top build quality coupled with the sealed SSO2 bearing results in an advertised MTBF (presumably at 25 ºC) of 150, 000 hours minimum to go along with a nice, long 6 year warranty that is backed by good customer support from Noctua. Let’s now take a look at the fan on the next page.
