Noctua: New 140 mm fans to premiere on a CPU cooler

Noctua's April 2024 roadmap

Noctua’s long-awaited next-gen fans in the 140mm format have experienced a setback in their planned release, but they also haven’t. They have indeed been delayed from the second to third quarter of 2024 in terms of standalone availability, but they should be out soon together with the cooler that replaces the NH-D15 at the top of the lineup. In addition, it’s also been somewhat declassified which of the “older” projects is nearing completion.

Noctua’s April roadmap is rather remarkable. Compared to the previous and relatively recent roadmap (from March this year), virtually all of the upcoming stuff has some new information added to it.

If we take it in turn, one at a time, we can start with the already released NH-L12Sx77 top-flow cooler suitable for SFF systems and narrower or shorter cases. This cooler has been available for about a week now, but it’s worth a reminder. Especially since we haven’t written a separate report on it.

Next in line is an “Undisclosed project”. In this case, it is possible that this will be the desk fan that Noctua presented back in 2018, which has not yet been released. That this could be the case is supported by the recently released Noctua trailer (on the social network X) for one of its upcoming products, the details of which quite clearly refer to design details corresponding to a desk fan.

As was the case in the previous roadmap, the successor to the NH-D15, which Noctua initially referred to as the NH-D15 v2, remains in the second quarter. With this cooler, that’s the end of it as far as Noctua’s planned products in the period until June 30th are concerned. This means that the new fans that the NH-D15 v2 cooler will use will be released separately at a later date as well. Unless we are mistaken, this is something that has not yet been done in any plans. I mean, of course, even if the cooler and fans were planned in the same quarter, it could have meant an earlier release of the cooler (for example, a month or two), but it’s now unambiguous. For answers as to why this is the case, we reached out to Noctua reps, and there are basically two reasons for this.

So first of all, it really is true that Noctua’s current plans see the release of the cooler before the standalone fans. This is partly related to the recent technical issues around the frame, where under certain circumstances when mounting on radiators, there were possible difficulties due to the deformation of the frame and the eventual collision of the blades with the tunnel. As far as this is concerned, it depends on a number of factors and it is the torque of the screw combined with the compressive load, which is also dependent on the specific type of thread. However, these complications only apply to the A14 fan models.

However, the models with a circular frame, which will be part of the upcoming dual-tower cooler, do not expect to be mounted on radiators. Although these are still 140 mm “sterrox” fans, they have a smaller mounting hole spacing (corresponding to 120 mm models) and mounting on radiators is not considered, so there is no risk of unwanted deformation under any circumstances that may occur in practice. Here Noctua has everything under control and there is nothing in principle preventing the early release of these fans.

Fans primarily intended for cooler heatsinks are mounted on them using clips or self-tapping screws, or anti-vibration spikes. The last one is for use in cases, for which these fans can also be suitable. In cases where the case in question does not have mounting holes for a 140 mm fan (but only 120 mm) and at the same time there is no excessive blockage of the larger impeller within the clearance of the bracket in the case. Based on this, it would seem that Noctua might release this type of A14 fan sooner than the square frame models, but this is not the case. This is because what also comes into play is the need to be able to satisfy the demand for fans that will arise with the CPU cooler, production-wise.

If both the coolers and the fans come out at the same time, the result could probably be weaker availability of one or the other product, which Noctua naturally wants to avoid and focus on selling fans separately at a later date.

The fans are planned for the third quarter and we can be more precise here. It is unlikely that their release will happen before September. And of course, this is again just a preliminary estimate and although we believe that the calendar won’t be rewritten this time, we can’t rule out the possibility that the release of the fans will be delayed again. The same goes for the top of the line dual-tower CPU cooler. In the chromax.black variant, the new generation of 140 mm fans should be released in about half a year’s time.

Of the smaller projects, small, 60mm fans with a 15mm profile are likely to come out at the end of the year. Prototypes of these may also appear at the upcoming Computex. After it’s over, there should be room for a detailed analysis of the technical features that have both troubled and excited things lately about the 140-millimeter fans, which will hopefully hit the shelves at least in some form (on a cooler).

Hell froze over, Noctua is working on a liquid cooler. It’s very special

Now that’s news we didn’t expect from Computex 2024: Noctua, possibly the most famous coolers and fans company, has presented a liquid cooler. What’s unusual is that Noctua is focused on silent operation (which liquid cooler pumps tend to have a problem with) and reliability, and has insisted on not making any AIO liquid coolers, until now. Noctua’s liquid cooler, however, takes a different route than usual. Read more “Hell froze over, Noctua is working on a liquid cooler. It’s very special” »

ID-Cooling has a super cheap 360 mm AIO cooler

While the vast majority of high-performance AIO coolers are priced well above the most powerful tower coolers, ID-Cooling goes in the opposite direction. Their liquid cooler, referred to as the FX360 Pro, is cheaper and at the same time on the outside there is no indication that it shouldn’t have a high TDP. The manufacturer claims 350W, which are backed by a large radiator, what seems to be a powerful pump, and the fans don’t look bad either. Read more “ID-Cooling has a super cheap 360 mm AIO cooler” »

Endorfy Fera 5 Black – Bestseller on the way to darkness

Today marks the launch of a new version of the popular Endorfy Fera 5 cooler, with the Black attribute. The name suggests that this cooler has a matte black finish, which will be appreciated especially by fans of minimalist PC builds. Of course, it will have to be tested whether this finish has a negative effect on cooling efficiency or whether there is any deterioration in acoustics. So let’s venture into the dark future of Endorfy coolers together. Read more “Endorfy Fera 5 Black – Bestseller on the way to darkness” »

  1. Based on certification sites, the round variant of the Gen 2 A14 will be called A14x25r this time, similar to the naming scheme of A12x25r. That also means the dimensions are indeed 140×140 instead of 150×140 like the A15.

    1. Thanks for the heads up, we have removed the A15 designation of the fan variant with the circular frame from the text, as it will probably be different versions of the A14.
