Price Comparison
When it comes to price, the Thermalright Burst Assassin 120 SE ARGB CPU Air Cooler is significantly more affordable at C$29.90, compared to the be quiet! Pure Loop 3 280 mm Liquid Cooling System, which is priced at C$138.51. This price difference of over C$108 highlights the value proposition of each cooler based on their respective features and performance capabilities. For users on a budget or those looking for basic cooling solutions, the Thermalright option presents a compelling choice without breaking the bank.
Cooling Performance
The be quiet! Pure Loop 3 280 mm is designed for immense cooling power, suitable for high-performance applications. Its liquid cooling system is capable of maintaining low temperatures even during peak CPU usage, making it ideal for gamers and content creators. In contrast, the Thermalright Burst Assassin 120 SE features a single tower design complemented by six nickel-plated heat pipes, which ensure effective heat dissipation. Although it operates efficiently, it may not match the Pure Loop's cooling capabilities, especially under heavy workloads.
Noise Levels
Noise levels are crucial for system builders looking for quiet operation. The be quiet! Pure Loop 3 operates at a maximum of 36.8 dB(A) when the fans are at full speed, which is relatively quiet for a liquid cooler. On the other hand, the Thermalright Burst Assassin 120 SE boasts a maximum noise level of 25.6 dB(A), making it quieter than the Pure Loop. This lower noise output could be a deciding factor for users who prioritise a silent computing experience, particularly in home or office environments.
Fan Technology
In terms of fan technology, the be quiet! Pure Loop 3 utilises two Pure Wings 3 140mm PWM fans that are engineered for high air pressure and offer quiet operation. The fans also feature a closed-loop motor function, ensuring a constant speed regardless of resistance. Conversely, the Thermalright Burst Assassin 120 SE is equipped with a TL-C12C-S PWM fan that operates at up to 1550 RPM, providing efficient airflow of 66.17 CFM. While both products feature PWM technology for variable speed control, the larger fans in the Pure Loop may provide better performance in demanding scenarios.
Installation and Maintenance
The be quiet! Pure Loop 3 offers an easy installation process with its flexible tubes and accessible recharge port, allowing for straightforward maintenance and refilling when necessary. This feature is particularly advantageous for users who appreciate the convenience of liquid cooling systems. In comparison, the Thermalright Burst Assassin 120 SE also features detailed optimisations for installation, including compatibility with various CPU sockets and a design that avoids memory height limitations. However, the maintenance of air coolers generally requires less effort than liquid cooling systems, making the Thermalright potentially easier for users who prefer simplicity.
Aesthetics and Design
Aesthetics can play a significant role in choosing a CPU cooler. The be quiet! Pure Loop 3 is designed without RGB lighting, appealing to purists who want a sleek, premium look without flashy effects. Its cooling block is noted for its elegant design, enhancing the overall appearance of any build. Conversely, the Thermalright Burst Assassin 120 SE features ARGB lighting, providing an opportunity for users to customise their systems with dynamic lighting effects. This difference makes the Thermalright more suitable for users looking to create a visually striking setup.
Compatibility
The compatibility of CPU coolers with various motherboard sockets is essential for ensuring a seamless build experience. The Thermalright Burst Assassin 120 SE supports a broad range of sockets, including Intel LGA 1150 to 1700 and AMD AM4 to AM5. This extensive compatibility makes it a versatile option for different builds. On the other hand, the compatibility specifics of the be quiet! Pure Loop 3 are not detailed in the provided data; however, liquid coolers generally require specific mounting brackets. Users should verify compatibility based on their specific CPU and motherboard before making a decision.
Which should you buy?
Choosing between the be quiet! Pure Loop 3 280 mm Liquid Cooling System and the Thermalright Burst Assassin 120 SE ARGB CPU Air Cooler ultimately depends on your specific needs and preferences. If you are looking for superior cooling performance, particularly for high-demand applications, the Pure Loop 3 is a great choice, despite its higher price of C$138.51. However, if budget, noise level, and ease of installation are your primary concerns, the Thermalright model at C$29.90 offers excellent value and effective cooling.
