Overview of the Products
In this comparison, we will examine the Noctua NH-U12S Redux and the Thermalright Peerless Assassin 120 Vision MAX ARGB Black CPU cooler. The Noctua cooler is priced at C$62.95, while the Thermalright model is priced at C$78.59. This price difference of C$15.64 may influence your decision, especially considering what each cooler has to offer in terms of performance and features.
The Noctua NH-U12S Redux is a streamlined version of its award-winning predecessor, designed for excellent compatibility and quiet operation. On the other hand, the Thermalright Peerless Assassin boasts a dual-tower design, promising enhanced cooling efficiency and innovative features like an LCD screen. Both coolers cater to different user needs, making this comparison essential for potential buyers.
Cooling Performance
When comparing cooling performance, the Thermalright Peerless Assassin clearly stands out. It features a dual-tower design with six pure copper heat pipes and a fan speed of up to 2150 RPM, delivering superior cooling efficiency. This configuration allows for an airflow rating of 69 CFM, ensuring effective heat dissipation during intensive tasks.
In contrast, the Noctua NH-U12S Redux utilises a single 120mm fan with a maximum speed of 1700 RPM. While it is designed for quiet operation and is capable of handling typical CPU loads, it may not match the aggressive cooling capabilities of the Thermalright model under heavy workloads. Thus, for users prioritizing maximum cooling performance, the Thermalright offers a significant advantage.
Design and Aesthetics
In terms of design, the Thermalright Peerless Assassin features an innovative dual-tower setup and a magnetic top cover with a 5-inch IPS LCD screen that displays system information. This unique feature adds a modern touch, appealing to users who enjoy visually monitoring their system’s performance. The matte black coating enhances its aesthetic appeal, allowing it to blend seamlessly with various builds.
Conversely, the Noctua NH-U12S Redux embraces a more traditional approach with its slim profile, making it highly compatible with most tower cases and RAM configurations. Its understated design reflects Noctua's reputation for quality and functionality. While it may lack flashy elements, its solid build and practical design are ideal for users prioritizing functionality over aesthetics.
Noise Levels
In terms of noise levels, the Noctua NH-U12S Redux is engineered for near-silent operation at idle, thanks to its NF-P12 redux-1700 fan. This makes it an excellent choice for users who are sensitive to noise, especially in quiet environments like home offices or gaming setups.
On the other hand, the Thermalright Peerless Assassin can operate at a maximum noise level of 27 dB(A). While this is relatively quiet, it may not achieve the same level of silence as the Noctua under low-load conditions. For users who value a whisper-quiet operation, the Noctua might be the better option, although the Thermalright still offers respectable performance without excessive noise.
Compatibility
Compatibility is a crucial factor when selecting a CPU cooler. The Noctua NH-U12S Redux has a height of 158mm, which allows it to fit comfortably in most tower cases without overhanging RAM slots or blocking PCIe slots on ATX and Micro-ATX motherboards. This makes it a versatile option for a wide range of setups.
The Thermalright Peerless Assassin stands at 164mm, which is still compatible with most mainstream ATX cases. However, its larger size could potentially lead to clearance issues in tighter builds, especially concerning tall RAM heat spreaders. While both coolers are compatible with Intel and AMD sockets, the Noctua offers slightly better versatility in terms of case compatibility.
Installation Process
Installation is a key consideration for many users. The Noctua NH-U12S Redux includes the SecuFirm2 mounting system, which simplifies the installation process on various Intel and AMD platforms. The inclusion of high-quality NT-H1 thermal paste further enhances the user experience by ensuring optimal thermal conductivity right out of the box.
In contrast, the Thermalright Peerless Assassin’s installation process is also straightforward, aided by its dual-fan design and nickel-plated copper base. However, the additional complexity of its dual-tower design may require a bit more attention during installation compared to the Noctua. Overall, while both coolers are designed for easy installation, the Noctua may be more user-friendly for those who prefer a simpler setup.
Price-to-Performance Ratio
When evaluating the price-to-performance ratio, the Noctua NH-U12S Redux shines with its C$62.95 price tag, offering excellent value for users seeking reliable cooling without breaking the bank. Its strong performance in a slim profile makes it particularly appealing for budget-conscious buyers.
The Thermalright Peerless Assassin, priced at C$78.59, provides advanced features such as a dual-tower design and an LCD screen, which can justify the higher cost for users who need superior cooling and enhanced aesthetics. However, for those who are primarily concerned with price and fundamental cooling performance, the Noctua remains a compelling choice.
Which should you buy?
Choosing between the Noctua NH-U12S Redux and the Thermalright Peerless Assassin 120 Vision MAX ARGB ultimately depends on your specific needs. If you prioritize quiet operation, ease of installation, and a lower price point, the Noctua is the better option. However, if you seek maximum cooling performance and innovative features like an LCD display, the Thermalright may be worth the additional investment. Both coolers have their strengths, so consider what aspects are most important for your particular setup before making a decision.
