Introduction to CPU Coolers
When it comes to maintaining optimal temperatures for your CPU, choosing the right cooler is crucial. In this comparison, we’ll evaluate the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler against the Noctua NH-U12A chromax.Black. Both coolers are popular choices among PC builders and enthusiasts, but they cater to different needs and budgets.
Design and Aesthetics
The Thermalright Peerless Assassin 120 SE ARGB features a sleek design with vibrant ARGB lighting, making it a visually appealing option for gamers and aesthetic-conscious users. Its dimensions are 125(L)x135(W)x155(H)mm, allowing it to fit comfortably in a variety of cases. On the other hand, the Noctua NH-U12A chromax.Black showcases a more understated all-black design that has proven to integrate seamlessly into various colour schemes. This cooler stands at 158mm tall, providing excellent compatibility without overhanging RAM slots or blocking PCIe slots. The design choices of both coolers reflect their intended audiences, with Thermalright appealing to those who prefer flashy visuals, while Noctua caters to users who favour a more classic look.
Cooling Performance
Performance is a key factor in any CPU cooler comparison. The Thermalright Peerless Assassin boasts a TDP rating of 120 to 245W, supported by its double tower design and six pure copper sintered heat pipes. This configuration enhances its cooling capabilities, ensuring effective heat dissipation during intense workloads. Conversely, the Noctua NH-U12A chromax.Black is renowned for its top-tier performance in a compact size, which has garnered over 100 awards and recommendations. The dual NF-A12x25 fans provide robust cooling while maintaining whisper-quiet operation at idle. Both coolers offer exceptional performance, but the Noctua’s proven track record gives it an edge in reliability and efficiency.
Noise Levels
Noise levels are an essential consideration for many users, especially those seeking a quieter computing experience. The Thermalright Peerless Assassin operates at a maximum noise level of 25.6dB(A), which is relatively quiet for a cooler of its size and capability. In contrast, the Noctua NH-U12A is designed with Low-Noise Adaptors that allow for automatic speed control, ensuring that it remains unobtrusive during everyday tasks. While both coolers prioritize low noise levels, the Noctua’s advanced fan technology positions it as a quieter option under load, making it particularly appealing for users who value silence.
Installation and Compatibility
Installation ease and compatibility are vital for users looking to upgrade their cooling solutions. The Thermalright Peerless Assassin comes with metal fasteners compatible with Intel and AMD platforms, ensuring a straightforward installation process. It supports various CPU socket types, including Intel 115X/1200/1700 and AMD AM4. The Noctua NH-U12A chromax.Black also excels in this area, featuring the SecuFirm2 mounting system for easy installation across a range of Intel and AMD sockets, including LGA1851, LGA1700, and AM4. While both coolers offer excellent compatibility, the Noctua’s mounting system is particularly noted for its efficiency and user-friendliness.
Thermal Paste Quality
The quality of thermal paste can impact cooling performance significantly. The Thermalright Peerless Assassin does not specify the type of thermal grease included, leaving users to select their preferred option. In contrast, the Noctua NH-U12A chromax.Black comes with high-end NT-H1 thermal paste, known for its excellent thermal conductivity and ease of application. This inclusion not only simplifies the installation process but also ensures optimal thermal transfer from the CPU to the cooler, enhancing overall performance. Users looking for a complete package may find this aspect of the Noctua particularly advantageous.

For users willing to invest in a premium cooling solution, the Noctua offers long-term value that justifies the cost.
Brand Reputation and Warranty
Brand reputation can influence purchasing decisions, especially in the competitive market of CPU coolers. Thermalright has been a trusted name in the industry for over 20 years, focusing on the development of high-quality computer accessories. However, Noctua has garnered a reputation for excellence, having received numerous awards for its products. Additionally, the Noctua NH-U12A is backed by a 6-year manufacturer’s warranty, providing peace of mind for buyers.
