Overview of the Products

The Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler and the Noctua NH-D15 chromax.Black are two high-performance cooling solutions for CPUs, but they cater to different needs and budgets. With prices of C$46.90 and C$174.95 respectively, these coolers have distinct features that set them apart in the market.

Thermalright is known for its affordable yet efficient cooling products, while Noctua has built a reputation for premium quality and performance. When considering which cooler to choose, it's essential to understand the specifications and features that each product offers.

Cooling Performance

In terms of cooling efficiency, the Noctua NH-D15 chromax.Black shines with its dual-fan setup that provides maximum cooling performance comparable to many all-in-one water coolers. Its extra-wide 140mm dual-tower design, combined with six heat pipes, allows it to maintain lower temperatures even under heavy loads.

On the other hand, the Thermalright Peerless Assassin 120 SE ARGB features a double tower design and is equipped with two PWM fans that deliver an airflow of 66.17 CFM at a noise level of 25.6 dB(A). While it may not reach the same cooling performance as the Noctua, it still offers respectable cooling capabilities, especially for its price range.

Build Quality and Design

The Noctua NH-D15 chromax.Black is built with premium materials and boasts an award-winning design, having received over 300 accolades from international hardware websites. Its all-black aesthetic is versatile, fitting well with various builds while maintaining a professional appearance.

The Thermalright Peerless Assassin 120 SE ARGB, although not as decorated, provides a solid build with an aluminium heatsink and pure copper heat pipes. Its ARGB lighting adds a visually striking element, appealing to those who favour aesthetics in their PC builds. However, the thermal performance and overall build quality of the Noctua may justify its higher price point.

Noise Levels

Noise levels are a critical factor for many users, particularly those who prioritise a quiet computing experience. The Noctua NH-D15 chromax.Black features renowned NF-A15 fans equipped with Low-Noise Adaptors, ensuring that it operates whisper-quiet at idle while still providing full performance under load.

Conversely, the Thermalright Peerless Assassin 120 SE ARGB operates with a maximum noise level of 25.6 dB(A), which is reasonably quiet. However, it's expected that the Noctua's advanced fan technology will result in a quieter operation overall, especially during intensive tasks.

Compatibility

Compatibility is crucial when selecting a CPU cooler, and both the Thermalright Peerless Assassin 120 SE ARGB and the Noctua NH-D15 chromax.Black cater to a wide range of Intel and AMD sockets. The Noctua supports Intel LGA1851, LGA1700, LGA1200, LGA115x, as well as AMD AM5 and AM4 sockets, ensuring that it can accommodate the latest CPUs.

The Thermalright cooler also supports a variety of sockets, including Intel's 115X, 1200, 1700, and AMD's AM4. This flexibility makes both products suitable for most modern builds, but the Noctua's broader support range may provide an edge for users with specific motherboard configurations.

Installation Process

Ease of installation can significantly impact user experience, and both coolers come with their own mounting systems. The Noctua NH-D15 chromax.Black includes the SecuFirm2 mounting system, which simplifies the installation process on various platforms.

Meanwhile, the Thermalright Peerless Assassin 120 SE ARGB also comes with metal fasteners designed for both Intel and AMD platforms. However, the Noctua's reputation for easier installation may make it a more attractive option for users who prefer a hassle-free setup.

Price Consideration

Pricing is a major differentiator between the two coolers. The Thermalright Peerless Assassin 120 SE ARGB is priced at C$46.90, making it an appealing choice for budget-conscious consumers seeking solid performance without breaking the bank.

In contrast, the Noctua NH-D15 chromax.Black is significantly more expensive at C$174.95. While it justifies its price with superior build quality, performance, and features, it may not be an option for users who are looking for an economical solution.

Which should you buy?

Ultimately, the decision between the Thermalright Peerless Assassin 120 SE ARGB and the Noctua NH-D15 chromax.Black hinges on your specific needs and budget. If you are seeking a cost-effective cooler that still delivers decent performance and aesthetics, the Thermalright is a strong contender at just C$46.90. However, if you prioritise top-tier cooling performance, build quality, and quieter operation, the Noctua, despite its higher price of C$174.95, may be the better investment in the long run.
