Are you a fan of tan? Noctua's new Sterrox lineup

One of these two new fans from Noctua are constructed of Sterrox, which we have seen a fair amount of advertising for recently.  According to the PR, the new material should allow for tighter spacing between the fan blades and the frame of the fan; these feature a minuscule 0.5mm of clearance compared to the common gap of 1.5-3mm.   The Guru of 3D pulled out their anemometer to see if this design has any effect on airflow and in the case of the NF-A12, how the PWM, FLX and ultra low noise adapters change performance and acoustics.  Take a look through the full review to get your answers.

"Especially our fans and your fans, a review on that new Sterrox based Noctua fan. Well, that and many more newly released ones. Noctua recently released new Sterrox manufactured 120mm fans in a wide range of configurations. The NF-A12 series, however, has been a fan series they worked on for four years! In this group test, we'll put nine recent Noctua fans to the test, and compared them in cooling performance, noise levels and airflow."

I remember buying my sister a CM Hyper 212 EVO and the fan was noisy (found out later they apparently source DIFFERENT fans at different times)... so I replaced it with a suitable Noctua and it was completely silent.

The NEW fans I remember seeing in 2017(?)...they were an off-color reddish-orange then and a Noctua rep said that a SINGLE FAN replaced two fans.

That sounds impressive but there are actually rapidly diminishing returns in some situations so I think the second fan helped by only a few degrees but considering how awesome they are already that's great.

In other situations the difference is much larger.

If nothing else I've learned that good FANS are an investment as every other fan I've bought has died except my Noctuas over the last many years.

Hi Jeremy,

Seems that the NF-P12 Redux is not made of sterrox, only the NF-A12.

Good catch ... perhaps that is where redux comes into it?

The "redux" fans take the moulds for the previous generation of designs (those that have been superceded by new products) add re-use them for basic black plastic injection molding. There won't be any Sterrox "redux" fans until the current Sterrox fans are replaced.
