Overview of the Products

In the realm of CPU air coolers, the TR-Assassin X 120R SE V2 and the Thermalright Peerless Assassin 120 SE ARGB stand out with distinct features and advantages. The TR-Assassin is priced at £14.49, making it the more economical choice, while the Thermalright model comes in at £28.79, reflecting its advanced capabilities and design elements.

The TR-Assassin X 120R SE V2 is designed with a heatsink that measures 120mm in length, 71mm in width, and 148mm in height, crafted from a combination of aluminium and copper. In contrast, the Thermalright Peerless Assassin 120 SE ARGB is slightly larger at 125mm by 135mm by 155mm, also utilising aluminium for its construction. This difference in dimensions may influence compatibility with various cases and configurations.

Performance Comparison

When it comes to performance, both coolers are engineered to ensure excellent thermal management. The TR-Assassin boasts a maximum airflow of 66.17 CFM, facilitated by a single 120mm fan operating at 1550 RPM. On the other hand, the Thermalright Peerless Assassin matches this airflow but employs two PWM fans, which can enhance cooling efficiency and noise management.

Both coolers maintain a noise level of ≤25.6dB(A), ensuring that they operate quietly even under load. However, the use of dual fans in the Thermalright model could provide superior thermal performance, especially in overclocking scenarios or during intensive tasks.

Installation and Compatibility

Installation ease is a significant factor for many users, and both coolers offer thoughtful compatibility. The TR-Assassin fits in most ATX cases due to its compact height of 148mm, making it a versatile option. It supports a wide range of Intel and AMD sockets, including LGA1150 through LGA1700 and AM4/AM5, though it requires the original motherboard backplate for AM4/AM5 installations.

The Thermalright Peerless Assassin also supports a variety of sockets, including Intel’s 115X, 1200, 1700, and AMD’s AM4 and AM5. Its design leaves ample space for RAM modules, which is a crucial consideration for users with high-profile RAM. The additional mounting plates provided for various CPU socket platforms further enhance its installation flexibility.

Aesthetic Appeal

Aesthetics play a crucial role in modern PC builds, and here the Thermalright Peerless Assassin shines with its ARGB lighting effects. The colourful lighting can be customised, allowing users to match their build's colour scheme, while the TR-Assassin features static RGB lighting, which may appear more subdued by comparison.

Both coolers are visually appealing, but the dynamic lighting of the Thermalright model could be a deciding factor for those looking to enhance their PC's visual appeal. The choice between these two may come down to personal preference regarding RGB features.

Build Quality and Materials

In terms of build quality, both coolers are constructed with high-grade materials. The TR-Assassin utilises a combination of aluminium and copper, which is effective for heat dissipation. The Thermalright Peerless Assassin, however, includes six pure copper heat pipes that employ advanced AGHP (All-Ground Heat Pipe) techniques. This technology provides more efficient heat transfer, especially under varying orientations of the cooler.

The solid construction of both models ensures durability, but the Thermalright's use of advanced materials and technology could translate to better long-term performance and reliability.

Cooling Technology

Cooling technology is critical for maintaining optimal CPU temperatures, and both coolers leverage fan technology effectively. The TR-Assassin X 120R SE V2 features a single fan with robust airflow capabilities, while the Thermalright Peerless Assassin incorporates dual fans that work in tandem to enhance cooling performance.

Moreover, the Thermalright model’s design, which includes a double tower cooling structure, aims to provide superior cooling in demanding situations. This could make it the preferred choice for users who push their CPUs to the limits, such as gamers and content creators.

Noise Levels

Noise levels are a crucial consideration for users who prioritise a quiet working environment. Both the TR-Assassin and Thermalright Peerless Assassin operate at a maximum noise level of ≤25.6dB(A), making them suitable for silent builds.

While both models are designed to operate quietly, the dual fans in the Thermalright may allow for more efficient cooling at lower RPMs, potentially leading to quieter performance during heavy use. This could be an essential factor for users sensitive to noise.

Which should you buy?

Choosing between the TR-Assassin X 120R SE V2 and the Thermalright Peerless Assassin 120 SE ARGB ultimately depends on your specific needs and preferences. If you are looking for an economical option that provides solid performance and compatibility, the TR-Assassin is a commendable choice at £14.49.

However, if you desire enhanced cooling capabilities, aesthetic appeal with ARGB lighting, and superior technology, the Thermalright Peerless Assassin at £28.79 may justify the higher price. Each cooler has its strengths, and your decision should align with your priorities in performance, aesthetics, and budget.
