Compare: Phantom Spirit 120 vs Peerless Assassin 140

Design and Aesthetics:

Phantom Spirit 120

The Phantom Spirit 120 is a step up from the no frills clean look of the Phantom Spirit 120 SE and has two 120 millimeter fans, subtle Thermalright logo, and a flat textured design on the heatsink top. Other than the fine details. Additionally, this cooler look is also in line with other coolers from Thermalright with slight tweaks to the cooling engineering the primary differentiating factor.

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:

Phantom Spirit 120

This cooler has a similar installation components as many of the mainstream Thermalright designs, which is one of the easier installation setups. However, it also faces an issue regarding uninstalling this cooler, where the cooler is unable to slide/twist off the cooler to break the thermal paste seal. This might be necessary if the thermal paste has a strong hold between the cooler and the CPU.

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:

Phantom Spirit 120

The Phantom Spirit 120 presents a high-performance cooling solution in a compact form, competing with other premium coolers in the market. Its seven heat pipe dual tower setup, combined with two 120mm fans, makes it highly capable of handling the cooling demands of modern high-performance CPUs, positioning it as a top contender for effective cooling.

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:

Phantom Spirit 120

The Phantom Spirit 120 stands out for its exceptional cooling efficiency at a low noise level, making it an ideal option for those seeking a quiet setup while accommodating high-performance components.

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:

Phantom Spirit 120

The Phantom Spirit 120 cooler is easy to install, much like other Thermalright models. It's an upgrade from the 120 SE, featuring a neat textured design, two 120mm fans, and a subtle logo, staying true to Thermalright's style with a few improvements. This compact cooler delivers high-performance cooling with a seven heat pipe, dual tower setup, and it's pretty quiet too. It's a great choice for keeping high-end setups cool with minimal sound.

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.
