Overview of the Thermalright AXP90-X53 White and Thermalrlght Peerless Assassin 120 SE

The Thermalright AXP90-X53 White Low Profile ITX CPU Air Cooler is priced at $19.39, making it a budget-friendly option, while the Thermalrlght Peerless Assassin 120 SE CPU Air Cooler comes in at $32.90, about 70% more expensive. Both coolers are designed to effectively manage CPU temperatures, but they cater to different needs and setups.

The AXP90-X53 is ideal for compact ITX builds, with a low profile of just 53mm, making it suitable for tight spaces. In contrast, the Peerless Assassin 120 SE, with a height of 155mm, is designed for larger cases and offers greater cooling potential due to its dual-fan configuration and six heat pipes.

Cooling Performance

When it comes to cooling performance, the Thermalrlght Peerless Assassin 120 SE has a significant advantage. It features a dual tower design with six heat pipes and two 120mm fans, allowing it to achieve a maximum airflow of 66.17 CFM and a fan speed of 1550 RPM. This setup results in a rated noise level of just 25.6 dB(A), providing efficient cooling with relatively low noise.

On the other hand, the AXP90-X53, while still effective, has a maximum airflow of 42.58 CFM and a higher fan speed of 2700 RPM. However, it operates at a quieter noise level of 22.4 dB(A). While the AXP90-X53 is sufficient for lower TDP CPUs, the Peerless Assassin 120 SE is better suited for high-performance systems.

Size and Compatibility

The AXP90-X53 excels in size, standing at only 53mm tall, making it perfect for small form factor builds where space is at a premium. This cooler supports various CPU sockets, including Intel's LGA1700 and several AMD AM4/AM5 configurations. Its compact design ensures that it won't interfere with RAM or other components in tight spaces.

Conversely, the Thermalrlght Peerless Assassin 120 SE, measuring 125mm in length, 135mm in width, and 155mm in height, is designed for larger cases. It also supports a broad range of CPU sockets and features an asymmetric layout to enhance compatibility with graphics cards and motherboards. While it may not fit in smaller builds, it provides superior cooling for larger setups.

Installation Process

Both coolers feature user-friendly installation processes, but they cater to different types of builds. The AXP90-X53 comes with a simple installation guide and the necessary mounting hardware, making it straightforward to set up in compact cases. Its design is optimized for ITX motherboards, ensuring a hassle-free installation experience.

The Peerless Assassin 120 SE utilizes an SS2 install system with a metal pressure plate, which enhances contact with the CPU for better thermal transfer. Although it requires more space and careful consideration of case compatibility, it is designed to provide a robust cooling solution once installed. Both coolers require the use of the original motherboard's backplate for AMD installations.

Aesthetic Appeal

In terms of aesthetics, the AXP90-X53 showcases a sleek white finish that blends well with modern builds, especially those focused on minimalism. Its compact design allows it to remain unobtrusive in smaller cases, making it an attractive option for HTPC setups.

On the other hand, the Peerless Assassin 120 SE features an anodized brushed black top cover and a more substantial presence due to its dual-tower design. This cooler not only looks powerful but also signals its enhanced cooling capabilities. The aesthetic appeal of the Peerless Assassin may attract users looking for a striking cooler to match their high-performance components.

Price Comparison

The price difference between the two coolers is notable, with the AXP90-X53 priced at $19.39 and the Peerless Assassin 120 SE at $32.90, making the latter about 70% more expensive. While the AXP90-X53 is an attractive option for budget-conscious users or those with space constraints, the Peerless Assassin 120 SE justifies its higher price with superior performance and features.

Users should consider their specific needs and whether the additional cooling performance of the Peerless Assassin is worth the extra cost. For those looking for a reliable cooler for a compact build, the AXP90-X53 is hard to beat at its price point.

Noise Levels

When evaluating noise levels, the Thermalright AXP90-X53 operates at a quieter level of 22.4 dB(A), making it suitable for environments where silence is a priority, such as home theaters or quiet office setups. Its PWM fan adjusts speeds based on CPU temperature, ensuring efficient cooling without unnecessary noise.

In contrast, while the Peerless Assassin 120 SE's noise level of 25.6 dB(A) is still relatively quiet, it is slightly louder than the AXP90-X53. However, given its increased cooling performance, the noise level may be a worthwhile trade-off for users who prioritize thermal efficiency, especially in gaming or demanding applications.

Which should you buy?

Choosing between the Thermalright AXP90-X53 White Low Profile ITX CPU Air Cooler and the Thermalrlght Peerless Assassin 120 SE CPU Air Cooler comes down to your specific needs. If you have a compact build and prioritize a quieter operation at a lower price, the AXP90-X53 is an excellent choice at $19.39. However, if you require superior cooling for high-performance components and have the space for it, the Peerless Assassin 120 SE, priced at $32.90, offers enhanced performance and features that justify its higher cost.
