Overview of the ID-COOLING IS-55 Black and Thermalright AXP90 X47 Black

The ID-COOLING IS-55 Black CPU Cooler is priced at $39.99, while the Thermalright AXP90 X47 Black retails for $22.39, making the latter about 44% cheaper. Both coolers are designed for low-profile builds, catering to users looking for efficient cooling solutions in compact cases. This comparison will delve into their design, cooling performance, compatibility, noise levels, and overall value.

Design and Dimensions

The ID-COOLING IS-55 Black features a total height of 57mm, which is slightly taller than the Thermalright AXP90 X47 Black at 47mm. The design of the IS-55 is ultra-compact and aims to fit well within small form factor builds. In contrast, the AXP90 sports a robust all-metal platform with a back plate fastener, enhancing its durability. Both products embrace a low-profile ethos, making them ideal for Mini-ITX setups where space is a premium.

Cooling Performance

The ID-COOLING IS-55 Black boasts five heat pipes and a 120mm PWM fan, which provides a maximum airflow of 54.6 CFM. This configuration is designed to ensure excellent heat transfer from the CPU, making it suitable for demanding applications. The Thermalright AXP90 X47 Black, on the other hand, utilizes four 6mm heat pipes and a 92mm slim PWM fan. While its cooling capabilities are effective, the lower airflow may be a limiting factor for high-performance CPUs.

Compatibility

Both coolers offer impressive compatibility with various CPU sockets. The ID-COOLING IS-55 supports Intel LGA 1851/1700/1200/1151/1150/1155/1156 and AMD AM5/AM4. Similarly, the Thermalright AXP90 X47 is compatible with Intel 115X/1200 and AMD AM4/AM5. This wide range of compatibility ensures that users can find a suitable match for their systems, whether they are using older or newer processors.

Noise Levels

In terms of noise levels, the ID-COOLING IS-55 Black operates at a noise range of 13.8-31.2 dB(A), thanks to its PWM fan that adjusts speed based on cooling needs. This feature allows for a quieter operation during less demanding tasks. The Thermalright AXP90 X47 Black has a maximum noise level of 22.4 dB(A), which is relatively quiet but does not provide the same low-end noise performance as the IS-55. For users sensitive to noise, the IS-55 may be the better option.

Build Quality

The build quality of both products reflects their respective brands' commitment to durability. The ID-COOLING IS-55 features a solid construction with five heat pipes that enhance thermal conductivity. The Thermalright AXP90 X47 Black utilizes a black nickel plating process, which provides corrosion resistance and low thermal resistance, contributing to its overall longevity. Both coolers show attention to detail, but the material choices may influence long-term performance and reliability.

Price-to-Performance Ratio

At $39.99, the ID-COOLING IS-55 Black is priced higher than the Thermalright AXP90 X47 Black by about $17.60. However, the additional features, such as better airflow and a more sophisticated heat pipe design, may justify the higher price for users needing enhanced cooling performance. In contrast, the AXP90 X47 offers solid performance at a more budget-friendly price, making it an attractive option for those looking to save without sacrificing too much in terms of efficiency.

User Experience and Installation

Both coolers are designed with user experience in mind, but the installation process may vary. The ID-COOLING IS-55 Black is tailored for easy installation on ITX motherboards, providing excellent RAM compatibility even in tight spaces. The Thermalright AXP90 X47 Black, with its all-metal platform and back plate fastener, also promises a straightforward installation. However, the overall user experience might hinge on the specific motherboard and case used.

Which should you buy?

Choosing between the ID-COOLING IS-55 Black and the Thermalright AXP90 X47 Black ultimately depends on your specific needs and budget. If you require superior cooling performance and don't mind spending a bit more, the ID-COOLING IS-55 Black is an excellent choice. However, if you're looking for a more budget-friendly option that still delivers reliable performance, the Thermalright AXP90 X47 Black is a solid contender. Both coolers have their strengths, making them suitable for different users within the low-profile CPU cooler market.
