When comparing the Noctua NH-D15 and the NH-D15S, you’ll find yourself dissecting the pinnacle of air cooling technology. We’re looking at a battle between two close siblings renowned for their exceptional heat dissipation capabilities. The NH-D15 is a heavyweight champion with its dual-fan setup and substantial cooling towers. It has set a benchmark in the industry for high-performance air coolers that enthusiasts and professional PC builders have celebrated for years. But every legacy has its variations, and that’s where the NH-D15S comes into play.
This cooler takes the robust design of its predecessor and tunes it for improved compatibility. With a single fan design, the NH-D15S achieves an asymmetrical form that’s friendly to tall RAM modules and large PCIe components, which can be a game-changer for builders seeking the balance between top-tier cooling and component clearance. Whilst the NH-D15 aims for maximal cooling efficiency, the NH-D15S navigates the tight spaces of complex builds without sacrificing much of the performance its family name is known for.
In terms of pricing, we observe that the NH-D15 traditionally comes in at a higher price point, signaling its position as a premium product for those who want no compromises in cooling performance. Meanwhile, the NH-D15S is slightly more affordable, acknowledging its streamlined fan setup. Both products reflect Noctua’s dedication to quality and performance, but it’s the subtle distinctions that inform a builder’s choice. As we delve into their specifications and user experiences, we understand that these coolers cater to different needs while upholding the Noctua promise of excellence.

Comparison of Key Features
When evaluating the Noctua NH-D15 against the NH-D15S, it’s crucial to scrutinize their dimensions, cooling efficacy, and how they accommodate motherboard components. Noctua’s commitment to quality is evident in the thoughtful engineering of these coolers.
Dimensions and Size
NH-D15 adheres to a classic dual-tower design with generous dimensions, making it a sizable presence in your build. The NH-D15S, in contrast, implements an asymmetrical design that dedicates more space to RAM and PCIe slot clearance without a significant compromise in cooling surface area. Both utilize aluminum fins and have copper heat pipes, ensuring efficient heat dissipation.
Cooling Performance
| NH-D15 | NH-D15S |
| Dual 140mm fans | Single 140mm fan |
| Six heat pipes | Six heat pipes |
| Premium cooling | Nearly identical cooling |
Our comparison expresses that the NH-D15 presents a robust cooling performance thanks to its two fan setup. Nevertheless, the NH-D15S almost matches its counterpart’s performance with a single fan, reflecting Noctua’s efficient cooler design.
RAM and PCIe Clearance
The NH-D15S excels with an asymmetrical layout that offers better RAM and PCIe compatibility, particularly beneficial for motherboards with tall RAM modules or those that require unobstructed access to PCIe slots. The NH-D15, on the other hand, may pose compatibility challenges with its wider design, potentially conflicting with taller memory modules and expansion cards.
Installation and Compatibility
In evaluating the Noctua NH-D15 and NH-D15S, we observe notable similarities and differences in their installation and compatibility that are essential for users to consider. Both models feature the renowned SecuFirm2 mounting system, which ensures a user-friendly and secure installation process.
Mounting Systems
Our experience with the SecuFirm2 mounting system shared by both coolers has been predominantly positive. It is a testament to Noctua’s commitment to providing a straightforward installation. The mounting kits included with both the NH-D15 and NH-D15S support a wide array of sockets, including Intel’s LGA1150, LGA1151, LGA1155, LGA1156, LGA2011-0, LGA2011-3, LGA1366, LGA775, and LGA1700, and AMD’s AM2, AM2+, AM3, AM3+, FM1, FM2, and FM2+. For AMD’s more recent AM4 socket, users can request a complimentary NM-i3 mounting kit from Noctua, highlighting their dedication to adapting to current hardware requirements.
Motherboard Compatibility
Noctua’s NH-D15S distinguishes itself with improved RAM and PCIe compatibility, especially on motherboards with crowded layouts. The NH-D15S’s single-fan asymmetrical design enables better clearance around the memory slots, and its offset ensures no interference with the top PCIe slot. This feature is particularly beneficial for workstations and gaming PCs where these slots are essential.
| Cooler | Motherboard Socket Compatibility |
| NH-D15 | LGA115x, LGA2011-0, LGA2011-3, LGA1366, LGA775, LGA1700, AM2(+), AM3(+), FM1, FM2(+), AM4 (with NM-i3) |
| NH-D15S | LGA115x, LGA2011-0, LGA2011-3, LGA1366, LGA775, LGA1700, AM2(+), AM3(+), FM1, FM2(+), AM4 (with NM-i3) |
We’ve found that for users prioritizing ease of installation and a high degree of compatibility with their hardware, both the NH-D15 and NH-D15S deliver. However, for those with specific layout constraints, the NH-D15S might be the more appropriate choice.
Performance and Noise Levels
When comparing the Noctua NH-D15 and the NH-D15S, it’s important to consider both cooling efficiency and noise production. These factors are paramount for enthusiasts seeking optimal system performance without excessive sound levels.

Additional Considerations
When evaluating the Noctua NH-D15 versus the NH-D15S, we must consider aspects like warranty and support, as well as pricing and the overall value these coolers provide. These factors play a pivotal role for us, the consumers, in making an informed decision.
Warranty and Support
Pricing and Value
| Cooler Model | MSRP | Amazon Price Guide |
| NH-D15 | $99.90 | $87.77 shipped |
| NH-D15S | $79.90 | $74.97 shipped |
The NH-D15S tends to be priced lower than the NH-D15, especially noted in the suggested retail price and reflected in online listings like Amazon. Our assessments show that while the NH-D15S is a single fan version and slightly cheaper, it does not skimp on cooling efficacy. For us who need better RAM and PCIe clearance, the NH-D15S often presents a more cost-effective solution without sacrificing performance. It is essential for us to consider the inclusion of additional fans and whether that aligns with our cooling requirements or budget allowances. We find that both models offer compelling value but cater to slightly different needs within the high-performance air cooling market.
