Overview of the Thermalright AXP90 X47 Full Low Profile CPU Cooler

The Thermalright AXP90 X47 Full Low Profile CPU Cooler is designed for users who need a compact cooling solution without sacrificing performance. Priced at $33.99, it features a height of only 47mm, making it an excellent choice for small form factor builds. This cooler is equipped with four heat pipes and a 92mm PWM fan, ensuring effective heat dissipation. Its pure copper base enhances thermal conductivity, while the anti-oxidation protective layer helps maintain performance over time.

With an airflow of 42.58 CFM and a noise level of just 22.4 dB(A), the AXP90 X47 balances cooling efficiency with quiet operation, making it suitable for both gaming and office PCs. The cooler is compatible with various Intel and AMD sockets, ensuring versatility for different builds.

Overview of the Thermalright Peerless Assassin 120 Mini Black CPU Cooler

The Thermalright Peerless Assassin 120 Mini Black CPU Cooler is slightly more expensive, retailing at $34.39. It offers a more substantial cooling solution with six heat pipes and a 120mm PWM fan that can reach speeds of 1500 RPM. This cooler utilizes AGHP technology, which optimizes heat dissipation by addressing the effects of gravity through its innovative design.

The airflow rating of 66.87 CFM and a maximum noise level of 25.6 dB(A) indicate that while it may be slightly louder than the AXP90 X47, it compensates with significantly better airflow. This cooler is also compatible with a wide range of Intel and AMD sockets, ensuring it fits a variety of systems.

Performance Comparison

When it comes to cooling performance, the Peerless Assassin 120 Mini outshines the AXP90 X47 due to its higher airflow capacity of 66.87 CFM compared to 42.58 CFM. This difference translates to a more efficient heat dissipation, particularly beneficial for high-performance CPUs. The six heat pipes of the Peerless Assassin utilize AGHP technology that enhances thermal transfer, making it a great option for users who push their systems to the limits.

In contrast, the AXP90 X47 is tailored for low-profile applications, making it more suitable for compact builds where space is at a premium. While its performance is commendable for its size, it simply cannot match the cooling capabilities of the Peerless Assassin.

Noise Levels

In terms of acoustics, the Thermalright AXP90 X47 operates at a lower noise level of 22.4 dB(A), making it an appealing choice for users who prioritize a quiet computing experience. This low noise level is a significant advantage for office environments or for users who prefer silent operation during gaming sessions.

On the other hand, the Peerless Assassin 120 Mini has a maximum noise level of 25.6 dB(A). While this is still relatively quiet, it is noticeably louder than the AXP90 X47. For users who are sensitive to noise, this may be a factor to consider when choosing between the two coolers.

Size and Compatibility

The size of the coolers is a critical consideration when selecting a CPU cooler for a specific build. The AXP90 X47 boasts a compact design with a total height of just 47mm, making it ideal for smaller cases where space is limited. It supports multiple Intel and AMD sockets, ensuring compatibility with a wide range of processors.

In contrast, the Peerless Assassin 120 Mini is larger, measuring 125mm in length and 135mm in height. While it may not fit in every compact case, it provides superior cooling performance for those with sufficient space. Both coolers are compatible with a variety of sockets, but the AXP90 X47 has the edge when it comes to fitting into tight spaces.

Build Quality and Design

Both coolers exhibit high-quality construction, but they cater to different aesthetic preferences. The AXP90 X47 features a sleek, low-profile design with a pure copper base that not only enhances performance but also adds an elegant touch to any build. The anti-oxidation protective layer ensures durability over time.

Conversely, the Peerless Assassin 120 Mini showcases a fully blackened body with an antioxidant coating, giving it a modern, stealthy appearance. Its CNC precision micro-engraved copper base is another testament to its quality build. Users who appreciate aesthetics may lean towards the Peerless Assassin for its striking design.

Pricing Comparison

The Thermalright AXP90 X47 is priced at $33.99, making it about 1.2% cheaper than the Thermalright Peerless Assassin 120 Mini, which retails for $34.39. While the price difference is minimal, it may influence budget-conscious buyers looking for a low-cost cooling solution. The AXP90 X47's lower price point and compact design make it an attractive option for users with smaller builds.

However, the slightly higher cost of the Peerless Assassin comes with enhanced cooling performance and features, which may justify the additional expense for users seeking top-tier performance.

Which should you buy?

Choosing between the Thermalright AXP90 X47 Full Low Profile CPU Cooler and the Thermalright Peerless Assassin 120 Mini Black CPU Cooler ultimately depends on your specific needs.
