Noctua NF-P14 FLX Fan

The results below show the average temperatures (of the 4 cores and the 2 repeats) for the Noctua NF-P14 FLX and 2 other comparable fans.

Primarily it is quite obvious that this fan performs well against the likes of a very reputable Akasa Viper fan. It must be noted that the Akasa Viper only achieves lower temperatures due to the fact it is running at a quite fast 1900 rpm a full 700 rpm faster than the Noctua. This shows how good the Noctua is – also at these speeds the Noctua is nearly 8 dB(A) quieter while maintaining a very similar temperature. The Akasa Viper is of course smaller but is able at this speed to pump more air through the heatsink whereas the Noctua is designed to run quieter as it is designed to be a case fan more than a CPU cooler. Although it is clear it would perform very well at such and may lead to you having a quieter computer, the headroom for overclocking may be slightly less than with the Akasa Viper.

Noise Rating

Unfortunately it is very hard for us to confirm the noise levels omitted by these fans but it is quite clear to anyone listening that the Noctua is significantly quieter and if you gave the Akasa Viper fan 10 for loudest volume, the Nexus would have to be given an 8 but the Noctua would be right down at 5. Of course this is completely subjective and very much my own opinion but as a comparison between these 3 fans it should give some insight as to what you would actually hear. The main point here is Noctua stand to excel with quietness and they have certainly achieved that with this device.
