Thermalright Peerless Assassin 140 Black CPU Cooler vs Noctua NH-D12L

Overview of the Thermalright Peerless Assassin 140 Black and Noctua NH-D12L

The Thermalright Peerless Assassin 140 Black is priced at C$54.90, while the Noctua NH-D12L is significantly more expensive at C$131.95. This price difference highlights the varying target audiences and cooling capabilities of these two CPU coolers.

The Thermalright model features a twin-tower design with dual fans, aimed at providing efficient heat dissipation, particularly for users with larger chassis. In contrast, the Noctua NH-D12L is designed for low-height applications, making it suitable for compact builds such as 4U rackmount server cases. The choice between these two coolers will ultimately depend on your specific requirements and budget.

Cooling Performance

The Thermalright Peerless Assassin is engineered for superior heat dissipation with its dual fans operating at 1500 RPM, which can move air at a maximum of 66.17 CFM, while maintaining a noise level of 25.6 dB(A). This cooling prowess makes it an excellent choice for high-performance CPUs.

Conversely, the Noctua NH-D12L employs a state-of-the-art NF-A12x25r fan that is specifically designed for quiet operation. Even under load, it maintains whisper-quiet performance, thanks to its PWM functionality. This model excels in environments where noise is a critical factor, providing effective cooling without compromising on acoustic performance.

Compatibility

The Thermalright Peerless Assassin supports a broad range of CPU sockets including Intel LGA1150 through LGA1851 and AMD AM4/AM5. Its versatile mounting system makes it a suitable choice for various builds.

On the other hand, the Noctua NH-D12L is also highly compatible, fitting most modern CPU sockets, including AMD AM4/AM5 and Intel LGA1700, LGA1200, and LGA115x. Notably, its asymmetrical layout ensures 100% RAM compatibility, making it an ideal choice for builds that prioritise RAM clearance.

Size and Design

The Thermalright Peerless Assassin stands at a height of 158mm, making it suitable for larger cases and providing ample space for high-profile memory modules. Its twin-tower design not only enhances cooling efficiency but also adds an aesthetic appeal.

In contrast, the Noctua NH-D12L is a low-height cooler at just 145mm, designed specifically for compact builds. Its dual-tower configuration is balanced with an innovative layout that maximises performance while minimising space usage, making it an excellent choice for small form factor systems.

Installation Process

The installation of the Thermalright Peerless Assassin is facilitated by its all-metal fasteners and SS2 buckle system, which simplifies the process across various CPU models. The included Y-type adapter cable for the dual fans ensures straightforward connection, avoiding potential issues with motherboard fan headers.

The Noctua NH-D12L also prioritises ease of installation. It comes with the high-end NT-H1 thermal paste and a SecuFirm2 mounting system, making it compatible with a wide range of Intel and AMD sockets. This user-friendly approach reduces the hassle typically associated with CPU cooler installations.

Noise Levels

One of the standout features of the Thermalright Peerless Assassin is its operational noise level of 25.6 dB(A), which is relatively quiet for a cooler of its performance capability. The dual fans provide robust airflow without generating excessive noise, making it suitable for both gaming and work environments.

In comparison, the Noctua NH-D12L is renowned for its silent operation, particularly due to its advanced fan technology. Even under full load, the fan maintains a whisper-quiet performance, appealing to users who prioritise a silent computing experience.

Price Comparison

At C$54.90, the Thermalright Peerless Assassin presents an attractive price point, especially for budget-conscious builders looking for effective cooling solutions without breaking the bank. Its performance-to-price ratio is commendable, making it a solid choice for gamers and productivity enthusiasts alike.

In contrast, the Noctua NH-D12L, priced at C$131.95, positions itself in the premium segment of CPU coolers. While it commands a higher price, it justifies this with superior build quality and a reputation for exceptional performance and reliability, backed by a 6-year warranty.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 140 Black and the Noctua NH-D12L ultimately depends on your specific needs and budget. If you're looking for an affordable, high-performance CPU cooler that excels in larger cases, the Thermalright model is a compelling option. However, if you require a quieter operation and are working with a compact build, the Noctua NH-D12L, despite its higher price, offers unparalleled performance and compatibility. Each cooler has its strengths, making them suitable for different types of users.
