Hi! Here you car read about the technical backgrounds on why this works on current AM5 CPUs: noctua.at/en/offset-am5-mounting-technical-backgrounds

@@NoctuaVideos Not what I asked as this doesn't explain at all why the benefit is less on AM4 but thanks

Sorry to hear the response didn’t fully address your question, so we’ll provide a bit more detail. The link we shared explains why offset mounting works on AM5-based CPUs. This method isn’t necessary on AM4 CPUs because they use a single, centered monolithic die, meaning the primary heat source is already positioned at the center of the IHS. This eliminates the need for offsetting, as the cooler naturally aligns over the main heat source. Hope this clarifies things further! If you still have questions, please don’t hesitate to reach out.

Hi! In short, your cooler, which is compatible with AM4, is also compatible with AM5. The AM5 socket was released after your cooler was produced, so the compatibility may not be listed on the product box. However, the official product page has been updated to confirm AM5 compatibility. All Noctua AM4 mountings, except for those of the NH-L9a-AM4 and the NM-AM4-L9a/L9i, attach to the threads of the standard AM4 stock backplate. Since these backplate threads and their pattern are identical for AM4 and AM5, our AM4 mountings that use the standard AMD backplate also support AM5. If you’re moving to AM5, we recommend exploring the offset mounting brackets. By shifting the cooler downward (south), you may see an improvement in cooling performance of 1-3°C, provided there is enough clearance for the adjustment. For more details, please check here: noctua.at/en/offset-am5-mounting-technical-backgrounds

Yes, AM4 and AM5 mounting is identical, so NH-D15 supports both platforms!

With the NF-A14x25 G2, we have introduced our new Centrifugal Turbulator hub structure that further enhances the fan's performance: noctua.at/en/nf-a14x25-g2-aerodynamic-design-innovations.html This would not have been possible with the metal hub structure that we use for the NF-A12x25 and the Sterrox LCP material we use for the impeller is easily stiff enough that there is no risk for longevity or stability. We understand that this topic has been brought up by a KZbinr who experiments with 3D-printed impellers and that the metal hub is helpful for this, but we build our fans for customers who use them in real world applications. For real world usage, there is no drawback, and the new Centrifugal Turbulator enabled us to further fine-tune the fan's performance.

Thank you for your reply! Simple curiosity played a role :)

Dear Customer, Thank you for reaching out with your concerns regarding the correct installation of NF-A14x25 G2 fans on a radiator. The protruding pads you mentioned are called load relief pads, designed to ensure even pressure, helping prevent long-term deformation of the fan frame. This feature is essential given the ultra-tight blade clearance of just 0.7mm between the rotor and frame. One primary reason for these pads is that radiator housing and fan installation points are often not perfectly perpendicular (90°), causing torsional stress on the fan frame. These pads are engineered to compress under normal screw pressure, providing an ideal fit while reducing strain, so you should see hardly any gap after tightening. For installation, please tighten the fan screws only until a small gap, or none, remains, taking care not to over-tighten. The total compressive load across all four screws should stay under 30kg (approximately 0.15-0.25 Nm of torque for typical M3 or UNC 6-32 screws). With M4 or fine-thread screws, lower torque may still apply more compressive force, so please exercise extra caution. When installing on a new radiator, it’s recommended to thread the screws first without the fan. This can help remove any paint residue in the threads, reducing the torque needed for a secure and proper fit. Thank you again, and please feel free to reach out with further questions.

The next-gen 120mm fan is scheduled for launch in Q1 2025. You can follow all upcoming Noctua launches here: noctua.at/en/product-roadmap

RAM compatibility depends on the cooler you choose. Every Noctua cooler has basic clearance information stated on the product page. However, if you still have concerns about compatibility, we highly recommend visiting the Noctua Compatibility Center: ncc.noctua.at/ Here, you can cross-check motherboard and RAM compatibility. If you still haven't found your answer, you can always contact Noctua support at noctua.at/en/support/noctua-support.

Thank you for your kind words, continued support, and honest feedback! Having three versions of the base has no significant impact on the end price of the cooler. It boils down to the much larger copper cold plate, 8 heat pipes, and the use of Sterrox liquid crystal polymer for the fans, which costs roughly 4x more than conventional PBT plastic. It's about pushing the limits and further improving products, and while we understand that some users may not always find the financial justification (since the original NH-D15 is still a fantastic cooler to this day), the fact that you've gained significant performance improvements by just swapping the fans makes us happy and justifies our need to push the boundaries. :)

@@NoctuaVideos Hello did not expect an repply tbh, very nice. Noctua has been great, your products are just so well crafted, also your support is OUTstanding, as one of my 14 industrial PPC fans did fail years ago, and your support not only did replace it, but also added AM4 kit, all free of charge even shipping, and i gotta say, this act did show me that your company really care about its customers and products. I can say few things that will improve Noctua. I think the D15 G1 and G2 both can benefit from having factory 3 fan clips, as some of us would like maybe to add 3 fan (yes you will also sell extra fan if the D15 came with 6 total clips not only 4) on the cooler, no matter it would not make much of a difference. Also consider some way of producing fans that are better like the G2 fans, but to cost about the same as the G1 fans, as i have seen so many ppl being disappointed, with the price of D15 G2, and pointing that ThermalRight have coolers that cost 1/3 of the price, and 95% of the performance. And i gotta say they have some point there, i also think the D15 G2 should cost like 100$, and tge D15 G1, like less 70$. I know Noctua is premium brand but still, maybe there is a way.. Now for me the price of the G2 fans or D15 G2 is not a problem, as i have my ways of reducing the cost.. The G2 fans i got second hand were used 2 months and like brand new did cost me 40$, instead of 80$, for that price they are great... Similar with the NH D15 G2, if i find it second hand for much less i will buy it, also after selling my old D15 G1, i will get 40% of my money back... But that is just me, most ppl buy them new, and then the price is not appeling for them.. So consider to find a way to reduce the price, as most ppl will just buy some cheap AIO for 60-70$ or ThermalRight dual tower for the same price, and ignore Noctua... Also i have seen so many ppl to curse and swear on the Noctua classic color of the fans, they say the color is like sh!t, and they piss me off, as why they dont see the color as is maybe chocolate or coffee, but cr@p... I find that now D15 G1 ChromaX with the classic fan colors of the G2 fans it look so slick and cool, as the original AF15 G1 fans in black are kinda booring...

Hi! Performance-wise, your cooler is fully compatible with the new CPU, but you will need an AM5 mounting kit. Please use the following link to apply for a free mounting kit: noctua.at/en/amd-am5-mounting-kit-order-form All you need is proof of purchase (invoice) for the cooler itself and the AM5 motherboard or the new AM5 socket CPU.

@@NoctuaVideos oh, so i still need the new mounting kit then, i dont think i can wait that long if i request for a free one from you guys, ill just buy the am5 mounting kit locally, itll be faster, what is the specific name of the mounting kit tho?if you dont mind.

​@@dongenesis5891 Hi! Actually, your existing cooler can be mounted on any AM5 motherboard without any issues or additional parts required. However, we do recommend getting the NM-AMB15 offset bars, which allow you to mount the cooler in an offset position to better target the CPU CCDs, achieving 1-3°C better cooling performance. Apologies for the incorrect initial information; I hope you haven't already purchased the AM5 kit.

@@NoctuaVideos the one i just bought is the NM-AM5/4-MP78 mounting kit. is this the right one or did i buy the wrong one?coz the only other mounting kit is the MP83

@@dongenesis5891 Hello! The NM-AM5/4-MP78 is the right set for the Noctua NH-U12A cooler.

Hi! If you are asking about the case, its the Phanteks NV9.

Hi! The stock of NF-A14x25 G2 fans should arrive to Japan in a matter of weeks.

Hello! It's best that you contact the Noctua support team and provide them with more information so they can try to troubleshoot the humming issue. It could be that some fan mounting rails are too close to the leading edge of the fan blades, and using intake spacers might help. However, we would greatly appreciate it if you could provide full feedback by emailing us at [email protected] or using our contact form at: noctua.at/en/contact

Thank you so much for sharing your story and for all the support over the years-we truly appreciate it! We completely understand your point. The NF-A14 is still a fantastic fan, and we’re proud of how well it has held up in the market. However, as we aim to push the envelope and deliver even better noise-to-performance ratios, the engineering and production costs inevitably increase, especially with the use of advanced materials like Sterrox liquid crystal polymer. While this technology isn't yet the standard for every PC fan, we hope you can understand the efforts behind it. Thank you again for your feedback and continued support! We hope to keep delivering great products for your future builds.

For all AMD AM5 socket-based CPUs the LBC version should provide the best results. Meaning that for the R9 7950X you should go with the LBC version.

The next-gen 120mm fan is scheduled for Q1 2025, so there's a chance for that as well. ;) The great thing is that users can upgrade older coolers with new fans at any time to achieve better acoustic performance. You can also follow our roadmap for upcoming product launches at: noctua.at/en/product-roadmap

Hi! Yes, it is! There's a small chance of interference with the motherboard, so please check visually if moving the cooler 7mm downwards might cause any issues with the PCIe slot, M.2 heatsinks, or other components. If you purchased the cooler a while ago and didn't receive the offset kit, you can order it for a small fee by filling out the form on our website: noctua.at/en/am5-offset-order-form

@@NoctuaVideos Thank you Noctua!

The NF-A14x25 G2 chromax.black is scheduled for Q1 2025. You can also follow our roadmap for upcoming product launches at: noctua.at/en/product-roadmap

Hello, my noctua has oxidized and has white spots. Is it possible to clean and remove them? Another question, does this pose any type of risk?, my D15S is already 10 years old.

Underrated comment. Laughed for like 10 straight minutes

It really depends on your requirements. If IP ratings (certified water and dust protection) are essential for your application, then the NF-A14x25 G2 might not be the best choice. For maximum airflow, the 3000 RPM iPPC model again, takes the lead. However, if you’re prioritizing quiet operation with high efficiency, the NF-A14x25 G2 is your top contender.
