Despite the higher price, the be Quiet! cooler offers advanced features that may justify its cost for some users.
Cooling Performance
The be Quiet! Pure Loop 2 FX 240mm is designed for effective cooling with its two high-speed PWM fans that provide excellent air pressure, coupled with an innovative pump designed to minimise noise and vibration. This cooler is particularly suited for users seeking a blend of performance and low noise levels, as it features a doubly decoupled PWM pump. In contrast, the Thermalright Peerless Assassin 120 boasts an effective heat dissipation area of 9600cm², supported by its dual-tower design and six heat pipes, allowing it to handle a thermal design power (TDP) of up to 245W. Therefore, while both coolers are built for performance, the be Quiet! product may appeal more to users prioritising quiet operation, while the Thermalright excels in raw cooling capability.
Design and Aesthetics
The be Quiet! Pure Loop 2 FX 240mm stands out with its stylish all-black design and aluminum-style accents, enhanced by its ARGB illumination that adds a vibrant touch. It also features an ARGB-PWM-Hub that allows for the synchronization of up to six ARGB components, making it a visually appealing choice for gamers and PC builders who value aesthetics. On the other hand, the Thermalright Peerless Assassin 120 offers an attractive white painted finish with colorful ARGB effects from its PWM fans. While both coolers feature ARGB lighting, the choice between them may hinge on whether one prefers the sleek, understated elegance of the be Quiet! cooler or the bright, eye-catching design of the Thermalright.
Installation and Compatibility
Both coolers showcase extensive compatibility with various Intel and AMD sockets, making them versatile options for most builds. The be Quiet! Pure Loop 2 FX supports sockets such as Intel 1700, 1200, and AMD AM4/AM5, ensuring a broad range of compatibility. Conversely, the Thermalright Peerless Assassin 120 also accommodates an impressive array of sockets, including Intel 1150, 1151, 1200, and AMD AM4/AM5.

However, the Thermalright's offset asymmetric layout allows for unrestricted installation on the first graphics card slot, which could be a crucial advantage for users with space constraints.
Noise Levels

Pure Loop 2 FX is engineered for quiet operation, thanks to its specially designed pump that reduces vibration and noise. Its focus on a tranquil environment makes it suitable for home offices or gaming setups where noise can be distracting.

This feature is particularly beneficial for those who plan to use their cooler for an extended period and want to ensure it operates efficiently. The Thermalright Peerless Assassin 120 does not mention similar maintenance features, which may suggest less focus on longevity. While both coolers are designed for durability, the be Quiet! model offers additional maintenance options that could result in a longer lifespan.
