Compare: Liquid Freezer II 240 vs Peerless Assassin 140

Design and Aesthetics:

Liquid Freezer II 240

Highlighted by its captivating ARGB lighting, this cooler presents a streamlined look with a pair of 120-millimeter fans adorning its 240mm radiator. Cable management concerns are efficiently addressed from the start through the pre-daisy-chained ARGB and RPM cords. A seamless blend is achieved with its black radiator, fan frames, and water pipes, tailored to complement darker cooler setups. It's worth noting that the water pump, though possessing a distinctive design, may exhibit a more understated aesthetic when juxtaposed with AIO coolers showcasing more intricate pump designs.

Peerless Assassin 140

The Peerless Assassin 140 shares a similar design with other 140mm coolers from Thermalright, featuring two 140mm heatsinks paired with a 120mm fan at the front and a 140mm fan in the middle. The difference in fan sizes helps reduce RAM clearance issues, which are common with most 140mm air coolers. This model has a polished top and comes in an all-black design, though other color options may be available.

Install Notes:

Liquid Freezer II 240

This cooler is relatively easy to install with the fans pre-installed on the radiator with the RPM connectors daisy chained neatly with a single connector coming out of the pump for the Fan inputs. However, this cooler requires it to be offset to the base mount, which can take some time to get right. Additionally, the heat pipes don't pivot from the pump which may make placement in certain setups difficult.

Peerless Assassin 140

The Peerless Assassin 140 CPU cooler features installation components similar to many mainstream Thermalright designs, making it relatively easy to install. However, it encounters a challenge when uninstalling, as it doesn't allow for sliding or twisting to break the thermal paste seal. This can be problematic if the thermal paste creates a strong bond between the cooler and the CPU.

Cooling Performance:

Liquid Freezer II 240

Despite its compact size, this cooler delivers impressive cooling power through its pair of 120mm fans. It matches the cooling performance of leading air coolers, making it an excellent choice for setups that demand efficient cooling while avoiding the bulkiness of traditional air cooling solutions. However, if you're seeking even higher performance beyond what an air cooler can offer, transitioning to a 360mm setup becomes necessary.

Peerless Assassin 140

While the cooler offers similar peak performance to its competitors, its main advantage lies in its efficiency at lower RPMs, where it provides slightly better cooling. This translates to a noticeable edge in noise-to-performance ratio compared to smaller coolers, making it quieter under lower loads while still maintaining strong cooling capabilities.

Noise Performance:

Liquid Freezer II 240

Operating with near-silent efficiency, the water pump ensures minimal noise disruption, while the pair of 120mm fans provide exceptional airflow at a manageable noise level. Consequently, the cooler excels in delivering impressive cooling performance with barely perceptible noise during typical usage scenarios. Nevertheless, when pushing a high TDP CPU to its limits, the cooler may produce some noise as it copes with the heightened heat load.

Peerless Assassin 140

Due to its larger fans, this cooler becomes more audible at higher RPMs. However, because the fans move more air, lower RPMs are generally sufficient for cooling under most moderate CPU loads, allowing for quieter operation without sacrificing performance.

Summary:

Liquid Freezer II 240

Enhanced by ARGB lighting, this cooler boasts dual 120mm fans situated on a 240mm radiator, ensuring efficient cooling with discreet black components that complement darker setups. The installation process is made convenient through pre-installed fans and daisy-chained RPM connectors. Despite its compact size, it delivers efficient cooling comparable to premium air coolers; however, for heightened performance demands, a 360mm setup might be better suited. Operating with minimal noise, the water pump and fans collaborate to maintain exceptional airflow at manageable sound levels. During regular use, it offers efficient cooling with a slight noise presence, yet handling high TDP CPUs during intensive tasks may result in increased noise due to elevated heat loads.

Peerless Assassin 140

The Peerless Assassin 140 CPU cooler is easy to install, thanks to its design resembling other mainstream Thermalright models, but it presents a challenge during uninstallation as it doesn’t allow for sliding or twisting to break the thermal paste seal. It features two 140mm heatsinks, a 120mm fan at the front, and a 140mm fan in the middle, which helps reduce RAM clearance issues common with larger coolers. While its peak performance is on par with competitors, it excels at lower RPMs, offering better cooling and a superior noise-to-performance ratio compared to smaller coolers. Although more audible at higher RPMs due to its larger fans, the slower speeds still provide sufficient cooling for most moderate CPU loads, ensuring quieter operation without compromising performance.
