be quiet! Dark Rock Pro 5 Air CPU Cooler vs Noctua NH-U12S redux

Cooling Performance and Technology

The be quiet! Dark Rock Pro 5 Air CPU Cooler offers a higher cooling capability with its 7 high-performance copper heat pipes and dual Silent Wings PWM fans, while the Noctua NH-U12S redux focuses on a slim design with a single 120mm fan. The Dark Rock Pro 5’s dual-fan setup includes a front fan with a funnel-shaped air inlet that provides extremely high air pressure, helping it maintain lower temperatures even during heavily overclocked CPU operations. In contrast, the NH-U12S redux features a quiet NF-P12 redux-1700 120mm fan designed for excellent cooling under load but with a more streamlined single-fan approach.

The Dark Rock Pro 5’s fans can operate in two modes: Quiet Mode with up to 1500rpm and Performance Mode reaching 2000rpm, allowing users to balance noise and cooling power. The NH-U12S redux offers automatic PWM speed control for near-silent operation at idle and full performance when required. Overall, the Dark Rock Pro 5 is likely the better choice for peak performance cooling needs, while the NH-U12S redux provides efficient thermal management in a more compact package.

Design and Build Quality

Design-wise, the Dark Rock Pro 5 clearly emphasises a distinctive, all-black aesthetic with a special black ceramic particle coating on its heat pipes, reinforcing both style and durability. Its detachable mesh top cover with an integrated middle fan adds a unique touch that complements the overall design language of be quiet! coolers. The mounting kit is entirely black, matching the cooler’s sleek finish.

On the other hand, the Noctua NH-U12S redux maintains the brand’s reputation for quality but takes a simpler approach in the redux line, focusing on affordability and streamlined design. Although it lacks the premium black coating and dual-fan integration, it still features the highly regarded SecuFirm2 mounting system and includes high-end NT-H1 thermal paste. The NH-U12S redux’s slim 120mm size and 158mm height allow it to fit comfortably in most tower cases without interfering with RAM or PCIe slots, emphasising practical compatibility over flashy design.

Noise Levels and Fan Technology

The Dark Rock Pro 5’s dual Silent Wings PWM fans incorporate advanced fluid-dynamic bearings and smooth 6-pole motors, reducing noise significantly even at higher speeds. The decoupled mounting system with vibration-isolating elements further minimises noise-generating turbulences. Users can select between Quiet Mode at 1500rpm or Performance Mode at 2000rpm, providing flexibility to prioritise silence or cooling power.

In comparison, the Noctua NH-U12S redux features the NF-P12 redux-1700 120mm fan with PWM control that balances full cooling performance under load with near-silent operation during idle. While the redux fan is quieter at idle, the Dark Rock Pro 5’s advanced fan technology and vibration isolation may provide a quieter experience overall during high-load scenarios due to its dual-fan design and noise-reducing features.

Installation and Compatibility

Both coolers are designed with ease of installation in mind, but the Noctua NH-U12S redux may edge out slightly for user-friendliness. Its SecuFirm2 mounting system is well known for straightforward, secure installation and supports a wide range of sockets, including Intel LGA1851, LGA1700, LGA1200, LGA115x, and AMD AM5 & AM4, making it highly versatile across current CPU platforms.

The Dark Rock Pro 5 also offers a clever installation concept with a pre-installed mounting bridge and fixing screws, plus a detachable top cover to facilitate assembly. However, its larger size and dual-fan configuration might require more careful handling during installation and could pose compatibility challenges in smaller cases compared to the NH-U12S redux’s slim 158mm height and 120mm fan size, which is designed to avoid overhanging RAM slots or blocking PCIe slots on most ATX and Micro-ATX motherboards.

Price and Value

The Noctua NH-U12S redux is priced at £65.68, making it the more affordable option between the two. It offers solid cooling performance, wide socket compatibility, and quiet operation at a relatively modest price point. This makes it a smart choice for users seeking quality cooling without a premium price tag.

The be quiet! Dark Rock Pro 5 Air CPU Cooler is priced at £75.99, reflecting its high-end features such as dual Silent Wings PWM fans, a special black ceramic-coated design, and advanced noise-reduction technology. Although it costs around £10 more than the NH-U12S redux, the price difference aligns with the added performance capabilities and premium build quality, positioning it as a worthwhile investment for users prioritising top-tier cooling and aesthetics.

Compatibility with PC Builds and Components

The NH-U12S redux’s slim 120mm size and 158mm height make it compatible with most tower cases and ensure it does not interfere with RAM or PCIe slots on a wide range of motherboard form factors, including ATX and Micro-ATX. This enhances its appeal for users building compact or standard-sized PCs who require a low-profile cooler that fits easily without component clearance issues.

In contrast, the Dark Rock Pro 5’s larger size and dual-fan setup may limit compatibility in smaller cases or tightly packed interiors. While it excels in cooling and noise control, its physical dimensions mean it is better suited to larger cases that can accommodate its full size. This trade-off between size and performance is important for buyers to consider based on their specific build requirements.

Brand Reputation and Product History

Both be quiet! and Noctua are renowned brands in the cooling industry, but they adopt slightly different approaches. The be quiet! Dark Rock Pro 5 continues the brand’s legacy of distinctive, high-end coolers known for combining silent operation with strong performance. The Dark Rock series has a rich history, and this model adds unique design accents while maintaining the well-recognised Dark Rock identity.

Noctua’s NH-U12S redux is part of an award-winning line, with the redux variant focusing on streamlining and affordability without compromising the quality expected from Noctua. The NH-U12S redux maintains the brand’s reputation for reliable performance and excellent build quality, making it a trusted choice for Intel and AMD users alike, especially for those looking for value without sacrificing compatibility or cooling efficiency.

Which should you buy?

The choice between the be quiet! Dark Rock Pro 5 Air CPU Cooler and the Noctua NH-U12S redux hinges on your priorities. If peak cooling performance, advanced noise reduction, and a premium, distinctive design are key, and you have the case space to accommodate it, the Dark Rock Pro 5 at £75.99 is the superior option. Its dual-fan setup, seven copper heat pipes, and dual operating modes deliver powerful cooling for overclocked or heavily loaded CPUs.

Conversely, if you seek a more affordable, compact cooler with excellent compatibility and solid performance, the Noctua NH-U12S redux at £65.68 offers excellent value. Its slim profile, broad socket support, and quiet NF-P12 redux fan make it suitable for most builds where space and budget are considerations.

Ultimately, the Dark Rock Pro 5 suits users who demand top-tier cooling and design at a slightly higher price, while the NH-U12S redux is ideal for those wanting efficient, quiet cooling in a more budget-conscious, space-friendly package.
