Price Comparison

The be Quiet! Pure Loop 2 FX 240mm is priced at C$118.12, whereas the Thermalright Peerless Assassin 120 Black CPU Air Cooler is significantly more affordable at C$54.90. This pricing difference of C$63.22 positions the Thermalright cooler as a budget-friendly option for those looking to enhance their CPU cooling without breaking the bank. While the be Quiet! product offers advanced features, the substantial price gap means that users must weigh their cooling needs against their budget constraints.

Cooling Performance

When it comes to cooling performance, the Thermalright Peerless Assassin stands out with its dual tower design and effective heat dissipation area of 9600 cm². The innovative AGHP technique with six 6mm heat pipes ensures that the cooler efficiently manages heat, making it suitable for demanding applications. In contrast, the be Quiet! Pure Loop 2 FX 240mm features two high-speed Light Wings 120mm PWM fans, designed for high air pressure and performance. Although both products aim to provide excellent cooling, the Thermalright cooler's advanced heat dissipation capabilities may give it an edge in high-load scenarios.

Compatibility

Both coolers offer broad compatibility with various CPU sockets, making them versatile options for different builds. The be Quiet! Pure Loop 2 FX supports Intel sockets including 1700, 1200, and 2066, as well as AMD's AM5 and AM4. On the other hand, the Thermalright Peerless Assassin also supports a wide range of Intel and AMD sockets, including LGA 1150/1151/1155/1156/1200/1700 and AM4/AM5. This similarity in compatibility ensures that users can choose either cooler based on performance and aesthetic preferences without worrying about socket compatibility.

Noise Levels

Noise levels play a crucial role in user experience, especially for those who value a quiet working environment. The be Quiet! Pure Loop 2 FX is designed for minimal vibration and quiet operation, thanks to its doubly decoupled PWM pump. While the specific noise level is not detailed, the emphasis on quiet operation suggests a focus on low noise output. In comparison, the Thermalright Peerless Assassin has a maximum noise level of 25.6 dB(A). Users seeking a whisper-quiet setup may find the be Quiet! cooler more appealing, but the Thermalright still offers a respectable level of noise performance for its price point.

Aesthetic Appeal

Aesthetics can significantly impact the choice of a CPU cooler, especially for builds that showcase components. The be Quiet! Pure Loop 2 FX boasts vibrant ARGB illumination and an all-black design, coupled with an aluminum-style finish that adds a touch of elegance to any setup. This cooler not only performs well but also enhances the visual appeal of a gaming or workstation rig. Conversely, the Thermalright Peerless Assassin features a sleek black finish, but lacks the advanced lighting options. While it maintains a professional look, visual customisation options are limited compared to its competitor.

Installation Ease

Installation is a crucial factor for many builders, and both coolers offer unique features to simplify the process. The be Quiet! Pure Loop 2 FX includes an easy-to-access refill port and comes with a coolant bottle, which can be a significant advantage for those who want a long-lasting cooling solution. The Thermalright Peerless Assassin is designed with metal fasteners for both Intel and AMD platforms, ensuring a straightforward installation experience. While both coolers are user-friendly, the Pure Loop's refill capability might appeal to those looking for longevity and convenience in maintenance.

Fan Efficiency

Fan efficiency is essential for effective cooling, and both products have their strengths. The be Quiet! Pure Loop 2 FX comes with two Light Wings 120mm PWM high-speed fans that provide high air pressure, which is vital for cooling performance, especially in tightly packed cases. The Thermalright Peerless Assassin also features two 120mm PWM fans, capable of delivering an airflow of 66.17 CFM at a fan speed of 1500 RPM. While both coolers aim to maintain optimal temperatures, the be Quiet! model's focus on high air pressure and design might result in superior performance under load, whereas the Thermalright cooler offers solid airflow at a lower noise level.

Which should you buy?

Ultimately, the choice between the be Quiet! Pure Loop 2 FX 240mm and the Thermalright Peerless Assassin 120 Black CPU Air Cooler depends on your specific needs and budget. If you're looking for advanced features, stylish aesthetics, and a reliable long-term cooling solution, the be Quiet! model is worth the investment at C$118.12. However, if budget constraints are a primary concern and you still want effective cooling, the Thermalright cooler at C$54.90 presents an excellent value proposition. Each cooler has its strengths, making them suitable for different types of users in the CPU cooling market.
