Design and Aesthetics:


Dark Rock Pro 5 (Quiet)

This cooler features a sleek black design that stands out. The signature Be-Quiet fan adds a unique touch, breaking away from the cooler's boxy appearance. Additionally, the top of the cooler boasts a clean design, contributing to a polished and refined look for your 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:


Dark Rock Pro 5 (Quiet)

The Dark Rock Pro 5 marks a notable advancement over its predecessors, featuring a mounting system that aligns with those of most mainstream coolers. This iteration enhances the design by securing the mounting bracket directly to the cooler, a change from the prior generation. Fan installation sees improvements too; the front fan comes pre-attached, ensuring perfect alignment, while the middle fan is designed to slide in from the top, secured by the top mount instead of side brackets. These enhancements significantly improve the cooler's setup and performance compared to the previous generation. Additionally, given the option to change the power speed on the top of the cooler, the middle fan has a 5 pin connector to facilitate this functionality, which forces you to use their connection rather than direct control through the motherboard.

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:


Dark Rock Pro 5 (Quiet)

There are two modes to this cooler, the performance mode and the quiet mode. The cooler selected covers the quiet mode of the cooler. Overall, this cooler provides better cooling than the average cooler tested. However, this cooler get's puts to its limits when placed under high loads. With that in mind, if you're looking to place this cooler on a CPU that produces a lot of heat, you may want to consider other options. Check out our temperature graphs to see how the cooler performance on your respective CPU.

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:


Dark Rock Pro 5 (Quiet)

This cooler maintains a quiet profile relative to the average coolers tested and won't start to make noticeable noise until around 70% fan speed. This offers a significant benefit compared to most coolers if you're looking for a quiet setup.

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:


Dark Rock Pro 5 (Quiet)

The Dark Rock Pro 5 represents a significant upgrade with its user-friendly mounting system and improved fan installation, ensuring better alignment and performance. It features a sleek design, enhanced by a signature quiet fan, and offers the ability to adjust power speed directly on the unit. This cooler excels in quiet mode, providing superior cooling under average loads but may reach its limits with high-heat CPUs. Its noise levels remain low up to 70% fan speed, making it ideal for those prioritizing a quiet setup.

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.
