Overview

When it comes to cooling your CPU, the Thermalright Peerless Assassin 120 Black CPU Air Cooler and the Thermalright Frozen Notte 240 Black ARGB Water Cooling CPU Cooler offer two distinct approaches. The Peerless Assassin 120 is an air cooler priced at C$54.90, while the Frozen Notte 240 is a water cooler retailing for C$62.90. Both products aim to provide effective cooling, but they do so through different technologies and design philosophies.

Cooling Performance

The Thermalright Peerless Assassin 120 boasts a significant effective heat dissipation area of 9600cm, utilizing a dual-tower design and two PWM fans that can achieve an airflow of 66.17 CFM at a maximum noise level of 25.6 dB(A). In contrast, the Frozen Notte 240 employs a dual-fan water cooling system designed to deliver higher cooling capabilities, with a maximum airflow of 72.37 CFM and a fan speed reaching up to 2000 RPM. The water cooler's design allows for lower resistance and enhanced cooling efficiency, making it suitable for overclocking.

Design and Aesthetics

The Thermalright Peerless Assassin 120 features a sleek black design with a full electroplating reflow welding process, ensuring not only functionality but also a modern look. Meanwhile, the Thermalright Frozen Notte 240 incorporates ARGB lighting that can synchronise with the motherboard, providing a vibrant aesthetic with a 1600W colour soft light effect. This visual appeal is a significant differentiator for those who appreciate styling alongside performance.

Noise Levels

In terms of noise output, the Thermalright Peerless Assassin 120 is quieter, operating at a maximum noise level of 25.6 dB(A). The Frozen Notte 240, while still relatively quiet, operates at a noise level of 27.7 dB(A) at maximum fan speed. If a quieter operation is a priority, the Peerless Assassin 120 has the edge, offering effective cooling with less auditory distraction.

Installation and Compatibility

Both coolers are designed for easy installation, supporting a wide range of Intel and AMD platforms. The Peerless Assassin 120 is compatible with various Intel sockets, including LGA 1150 through 2066, and AMD sockets such as AM4 and AM5. The Frozen Notte 240 also supports a broad spectrum of Intel and AMD sockets, including LGA 1150 through 2066 and AM4/AM5. However, the water cooler requires a chassis width greater than 250mm, which may limit installation options in smaller cases.

Build Quality and Durability

The Thermalright Peerless Assassin 120 utilizes high-quality aluminum and copper materials, ensuring durability and long-term performance. Its double tower cooling design enhances heat dissipation. The Frozen Notte 240 features a copper base and high-strength acrylic top cover, designed for durability while also incorporating a mirror plating process for aesthetics. Both coolers are built with longevity in mind, but the water cooler's components may require more maintenance over time.

Power Consumption

The Thermalright Peerless Assassin 120 operates with a power port of 4-pin at 12V, drawing less power during operation compared to the Frozen Notte 240, which also uses a 4-pin PWM interface but has a higher fan speed that may lead to increased power consumption. While both coolers are efficient, the Peerless Assassin 120 may be the better option for users looking to minimise energy costs.

Price Consideration

The price difference between the two is notable; the Thermalright Peerless Assassin 120 is priced at C$54.90, making it an attractive option for budget-conscious consumers. The Frozen Notte 240, at C$62.90, offers additional features such as ARGB lighting and enhanced cooling efficiency, justifying the higher price for those who value those aspects. Ultimately, your budget and specific needs will dictate which cooler presents the better value.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 Black CPU Air Cooler and the Thermalright Frozen Notte 240 Black ARGB Water Cooling CPU Cooler largely depends on your priorities. If you seek a cost-effective, quiet, and reliable air cooling solution, the Peerless Assassin 120 is a strong contender. However, if you desire superior cooling performance and appealing aesthetics with ARGB lighting, the Frozen Notte 240 justifies its higher price. Consider your specific requirements, including your CPU load, case size, and personal preferences, to make the best choice for your gaming or workstation setup.
