ARCTIC Liquid Freezer III Pro 360 A-RGB - AIO CPU Cooler vs Thermalright Peerless Assassin 120 SE CPU Air Cooler

Price Comparison

The ARCTIC Liquid Freezer III Pro 360 A-RGB is priced at £74.99, while the Thermalright Peerless Assassin 120 SE CPU Air Cooler is considerably more affordable at £29.99. This significant price difference of £45 underscores the varying target markets and technologies each cooler employs. The higher price of the ARCTIC cooler reflects its advanced AIO (All-in-One) liquid cooling technology, which typically offers superior cooling performance compared to traditional air coolers like the Thermalright. However, budget-conscious consumers may find the Thermalright’s price point more appealing, especially for mid-range builds where performance demands are moderate.

Cooling Performance

When it comes to cooling performance, the ARCTIC Liquid Freezer III Pro is designed for optimal heat dissipation with its integrated VRM fan and enhanced cold plate design. It features the P12 PRO FAN, which operates more efficiently under load, providing powerful cooling while keeping noise levels low. On the other hand, the Thermalright Peerless Assassin 120 SE employs a double tower cooling design supported by two PWM fans. While it boasts a maximum airflow of 66.17 CFM, its TDP rating of 120 to 265W indicates it can handle substantial heat but may not match the efficiency of a well-optimised AIO cooler under extreme conditions.

Installation and Compatibility

Installation can be crucial for CPU coolers, and both the ARCTIC and Thermalright models offer compatibility with popular Intel and AMD sockets. The ARCTIC cooler's native offset mounting design ensures efficient heat transfer by optimally aligning the cold plate over the CPU hotspot. The Thermalright cooler also provides comprehensive support for Intel (115X/1200/1700) and AMD (AM4) platforms, featuring metal fasteners for easy installation. However, the ARCTIC's integrated cable management may simplify the setup process by reducing cable clutter, making it potentially more user-friendly for those less experienced with PC builds.

Noise Levels

Noise levels are a critical consideration for many PC users, especially those who value a quiet working environment. The ARCTIC Liquid Freezer III Pro is designed to operate quietly, particularly at lower speeds, thanks to its advanced fan technology. Although specific decibel ratings are not provided, the emphasis on quieter operation suggests it is engineered to minimise noise during intense tasks. Conversely, the Thermalright Peerless Assassin 120 SE lists its noise level at a maximum of 25.6 dB(A), which is relatively low for an air cooler. This makes it suitable for users who seek a balance between cooling efficiency and acoustic performance without introducing significant noise into their setup.

Build Quality and Design

The build quality of a cooler can significantly impact its longevity and performance. The ARCTIC Liquid Freezer III Pro features a sophisticated design with an emphasis on optimised contact pressure distribution, enhancing both durability and thermal management. Its A-RGB lighting adds a visual appeal that may attract gamers and PC enthusiasts looking to enhance their build's aesthetics. In contrast, the Thermalright Peerless Assassin 120 SE is constructed from aluminium and features pure copper heat pipes, known for their excellent thermal conductivity. While it may not have the same visual flair, its robust construction aims to deliver reliable performance over time.

Brand Reputation

Brand reputation plays a significant role in the decision-making process for many consumers. ARCTIC is well-regarded for its innovative cooling solutions and commitment to quality, having established a strong presence in the PC cooling market. The Liquid Freezer series is particularly noted for its performance and reliability. On the other hand, Thermalright, with over 20 years of experience, has built a solid reputation in the air cooling sector, particularly among budget-conscious users. While both brands offer reliable products, ARCTIC's focus on high-performance liquid cooling may appeal more to enthusiasts, whereas Thermalright's offerings are well-suited for value-driven consumers.

User Experience

User experience often hinges on how well a CPU cooler performs in real-world scenarios. The ARCTIC Liquid Freezer III Pro, with its integrated VRM fan and advanced cooling technology, is designed for high-performance applications and could be ideal for gaming or heavy multitasking. Users may find that its effective cooling capabilities lead to better CPU performance and longevity. In contrast, the Thermalright Peerless Assassin 120 SE offers a straightforward installation experience and solid cooling performance for everyday use, making it an excellent choice for users who do not push their systems to extreme limits but still require reliable thermal management.

Which should you buy?

In conclusion, the choice between the ARCTIC Liquid Freezer III Pro 360 A-RGB and the Thermalright Peerless Assassin 120 SE largely depends on your specific needs and budget. If you are seeking high-end performance, particularly for gaming or demanding workloads, the ARCTIC model's advanced features and superior cooling capabilities justify its higher price of £74.99. However, if you are looking for an affordable and reliable cooling solution for standard computing tasks, the Thermalright cooler at £29.99 offers great value without compromising on essential performance. Ultimately, both coolers have their strengths, so consider your usage patterns and budget before making your decision.
