Overview of the ARCTIC Liquid Freezer III Pro 360 and TR-Peerless Assassin 120

The ARCTIC Liquid Freezer III Pro 360 is a high-performance AIO CPU cooler priced at £67.49, while the TR-Peerless Assassin 120 Digital ARGB White is an air cooler retailing for £35.89. Both products aim to provide efficient cooling solutions, but they cater to different preferences and needs in the CPU cooling market.

The ARCTIC cooler boasts a 360mm radiator, designed for optimal heat dissipation through its powerful P12 PRO fans, which are particularly effective at lower speeds. In contrast, the TR-Peerless Assassin features dual fans and utilises advanced AGHP heat pipe technology to combat heat effectively, making it a solid contender in the air cooling category at a more accessible price point.

Cooling Performance

In terms of cooling performance, the ARCTIC Liquid Freezer III Pro 360 offers superior capabilities with its larger surface area due to the 360mm radiator. This design allows for a greater volume of air circulation and heat dissipation, making it particularly effective under high loads. The fans are designed for increased power and quieter operation, ensuring efficient cooling even at low speeds.

On the other hand, the TR-Peerless Assassin, while compact with a height of 162mm, employs dual fans that produce a significant airflow of 88.89 CFM and operates at a fan speed of 1850 RPM. This configuration is engineered to provide efficient cooling and features PWM intelligent temperature control, which allows it to adjust fan speed dynamically based on CPU temperature. While it may not match the ARCTIC's cooling prowess under extreme conditions, it is still a competent cooler for most mainstream applications.

Design and Aesthetics

The design elements of the ARCTIC Liquid Freezer III Pro 360 focus on functionality and integration. It features a native offset mounting system for Intel and AMD processors, which enhances heat transfer efficiency by aligning the cold plate with the CPU hotspot. Additionally, its integrated cable management reduces clutter by concealing PWM cables within the sheathing of the hoses, creating a cleaner look inside the case.

Conversely, the TR-Peerless Assassin brings a striking aesthetic with its white colour scheme and digital ARGB lighting. The dual-tower design not only looks appealing but also enhances its performance, providing ample space for airflow. This cooler's design is particularly compatible with cases that support high-capacity components, such as large memory modules and graphics cards.

Installation and Compatibility

The ARCTIC Liquid Freezer III Pro 360 features a user-friendly installation process, with native mounting for both Intel and AMD platforms, including LGA1851 and LGA1700. This ensures that users can easily set it up without compatibility issues. The cooler's design also facilitates good cable management, which is often overlooked in many cooling solutions.

In comparison, the TR-Peerless Assassin 120 is designed to be widely compatible with several platforms, including AMD AM4/AM5 and various Intel sockets. This versatility allows it to cater to a broad range of builds, making it a flexible option for users looking to upgrade their cooling solution. Both coolers are well-suited for mainstream ATX chassis, although the ARCTIC’s 360mm size may require more spacious cases.

Noise Levels

Noise levels can significantly impact the user experience, especially in quiet environments. The ARCTIC Liquid Freezer III Pro 360 is engineered to operate quietly, particularly at lower speeds, making it an excellent choice for users who prioritise low noise levels during operation. Its P12 PRO fans are specifically noted for their reduced noise output while maintaining high cooling performance.

In contrast, the TR-Peerless Assassin 120 has an operating noise level of ≤25.6 dB(A). While this is relatively quiet, the dual fans may produce more noise under higher loads compared to the ARCTIC model. However, the cooling effectiveness of the TR-Peerless means that users might find the trade-off acceptable, especially given its lower price point.

Price Consideration

When comparing prices, the ARCTIC Liquid Freezer III Pro 360 is significantly more expensive at £67.49 compared to the TR-Peerless Assassin 120, which retails for £35.89. This price difference reflects the ARCTIC cooler's advanced technology and superior cooling capabilities. However, budget-conscious consumers might find the TR-Peerless to be a more attractive option, offering solid performance at a much lower price.

For users who prioritise performance and are willing to invest more for a premium cooling solution, the ARCTIC Liquid Freezer III Pro 360 justifies its higher price. Conversely, the TR-Peerless Assassin 120 presents a compelling value for those who need effective cooling without breaking the bank.

Brand Reputation

ARCTIC has established a reputation for producing high-quality cooling solutions that often receive positive reviews from the tech community. The brand is known for its commitment to performance and reliability, which is evident in the design of the Liquid Freezer III Pro 360. Users can expect a product that not only performs well but also offers longevity.

Similarly, TR has made a name for itself with innovative cooling products that balance performance and affordability. The Peerless Assassin 120 is designed to meet the needs of gamers and PC builders looking for reliable cooling without the premium price tag. Both brands have their strengths, making them reputable choices in the CPU cooling market.

Which should you buy?

Ultimately, the choice between the ARCTIC Liquid Freezer III Pro 360 and the TR-Peerless Assassin 120 hinges on your specific needs and budget. If you're seeking maximum cooling performance and are prepared to invest £67.49 for a premium AIO solution, the ARCTIC model is the clear winner. Its advanced features and superior cooling capabilities make it ideal for high-performance builds.

On the other hand, if you're looking for an effective cooling solution that balances performance and price, the TR-Peerless Assassin 120 at £35.89 offers excellent value. It provides sufficient cooling for most applications and is compatible with a wide range of systems. Ultimately, both products have their merits, and your decision should be guided by your cooling requirements and financial considerations.
