Design and Aesthetics:


Liquid Freezer III 240

This cooler showcases a sleek, symmetrical design with a modern aesthetic. While this model doesn’t include RGB lighting, there are versions available that do, allowing you to choose based on your style preferences. Overall, it adds a clean, contemporary look to your PC setup.

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 III 240

The Arctic Freezer III 240 retains the easy installation features of its predecessor while offering added convenience. What sets this cooler apart is its pre-installed fans on the radiator, simplifying the setup compared to other all-in-one (AIO) coolers. The detachable CPU mounting bracket further enhances the installation process by eliminating interference from aesthetic components. However, attaching the control cable to the motherboard can be challenging once the cooler is mounted. To avoid this, it’s advisable to connect the cable to the motherboard before installing the cooler.

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 III 240

The Arctic Freezer III 240 offers some performance improvements over its predecessor, the Arctic Freezer 240, but this comes with increased noise. Relative to other coolers in it's weight class, this cooler outperforms most.

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 III 240

The Arctic Freezer III 240 has a more powerful pump that has the potential to be quite audible. Since our testing was conducted with the AIO pump running at 100% speed, lowering the pump speed during less demanding tasks can help reduce noise levels without sacrificing too much performance.

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 III 240

The Arctic Freezer III retains its user-friendly installation design, featuring pre-attached radiator fans and a detachable CPU mounting bracket for simpler setup. However, connecting the control cable can be challenging once the cooler is installed, so it's best to attach it beforehand. The cooler sports a modern design, with some versions offering RGB lighting for added customization. While it boasts aesthetic improvements and lower noise levels compared to standard coolers and its predecessor, the Arctic Freezer 240, the Arctic Freezer III 240 delivers average performance and struggles to effectively cool high-core CPUs under heavy workloads.

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.
