Compare: FX360 Pro vs Peerless Assassin 140

Design and Aesthetics:

FX360 Pro

This cooler features a sleek, understated design, perfect for setups aiming for an all-black, stealth fighter aesthetic rather than a flashy, Times Square vibe. The AIO pump adds a touch of reflection, drawing attention to the center of your build. This minimalist style aligns well with those who prefer a clean, sophisticated look for their system, like myself.

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:

FX360 Pro

The installation of this cooler follows the standard procedure for mainstream AIO coolers. You will need to install the fans, which come with an easy daisy chain setup, making the process relatively simple. After connecting the fans, ensure the AIO pump brackets are set up and secure on the motherboard. Next, attach the radiator to the case, make sure the right mounting bracket is on the AIO pump, place the pump on the motherboard mounting brackets, and secure the AIO pump in place. Finally, connect the AIO pump cable to the motherboard pump input and the fans to the CPU input. Overall, this is what you would expect with most mainstream AIO coolers.

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:

FX360 Pro

The FX360 Pro offers excellent cooling performance for an AIO, making it capable of handling some of the hottest CPUs. Testing at 100% AIO pump speed demonstrates that this cooler has enough headroom to run at lower speeds for both the fan and pump while maintaining comfortable CPU temperatures, making it extremely competitive option at its price point.

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:

FX360 Pro

The base noise level is higher for this CPU drive due to the increased pump noise. However, since the testing is done at 100% pump speed, this can easily be toned down to quieter levels. With this in mind, the cooler can offer excellent cooling at moderate noise levels and also handle more demanding tasks, albeit with increased audibility.

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:

FX360 Pro

The FX360 Pro offers excellent cooling performance for an AIO, capable of handling some of the hottest CPUs. Installation follows the standard procedure for mainstream AIO coolers, with an easy daisy chain setup for the fans and straightforward attachment of the radiator and pump. The cooler features a sleek, understated design, ideal for those aiming for an all-black, stealth fighter aesthetic. Testing at 100% pump speed shows the cooler's headroom to run at lower speeds for both the fan and pump while maintaining comfortable CPU temperatures, making it a competitive option at its price point. Although the base noise level is higher due to the increased pump noise at full speed, this can be reduced to achieve quieter operation. The cooler can offer excellent cooling at moderate noise levels and handle more demanding tasks with increased audibility.

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.
