Updated August 2026 — full head-to-head comparison.
Overview of the ID-COOLING IS-55 Black CPU Cooler
The ID-COOLING IS-55 Black CPU Cooler stands out with its low-profile design, making it ideal for compact builds. Priced at $39.99, it is engineered to deliver efficient cooling performance with its five heat pipes and a PWM fan. The cooler's total height of 57mm allows for compatibility with various systems, including Mini-ITX and HTPC configurations.
With a maximum airflow of 54.6 CFM and a noise level range of 13.8 to 31.2 dB(A), the IS-55 prioritizes both cooling efficiency and quiet operation. Its compatibility with Intel LGA1851/1700/115X/1200 and AMD AM4/AM5 sockets further enhances its versatility, appealing to a wide audience of PC builders.
Overview of the Thermalright AXP120-X67
The Thermalright AXP120-X67 is a strong contender in the low-profile CPU cooler market, retailing for $27.99. This cooler is slightly taller at 67mm but offers a robust cooling solution with six heat pipes, ensuring excellent heat dissipation. Its design is optimized for both Intel and AMD processors, providing support for a range of sockets, including Intel LGA 1700 and AMD AM4.
Equipped with a PWM fan that achieves a maximum airflow of 59 CFM and a noise level of up to 26.1 dB(A), the AXP120-X67 aims to deliver both performance and quiet operation. The cooler also features advanced techniques such as the AGHP technique, which enhances cooling efficiency even under various orientations.
Performance Comparison
When it comes to cooling performance, the Thermalright AXP120-X67 slightly outperforms the ID-COOLING IS-55. The AXP120-X67 boasts a maximum airflow of 59 CFM compared to the IS-55's 54.6 CFM. This 4.4 CFM difference can be significant for users pushing their CPUs under load. Additionally, while the IS-55 operates at a lower noise level range, the AXP120-X67 maintains a competitive noise level of up to 26.1 dB(A), which is still relatively quiet for a cooler of its class.
Both coolers are designed for efficient heat dissipation, but the additional heat pipe in the AXP120-X67 may provide an edge in thermal management, making it potentially better suited for overclocking scenarios.
Design and Build Quality
In terms of design, the ID-COOLING IS-55 features a sleek, compact profile that is particularly beneficial for small form factor builds. Its total height of 57mm allows for compatibility with RAM modules and other components that might be obstructed by bulkier coolers.
On the other hand, the Thermalright AXP120-X67, while taller at 67mm, incorporates a durable all-aluminum construction with a copper base. This design not only enhances its thermal conductivity but also contributes to its overall sturdiness. Both coolers are designed to fit a variety of setups, but the IS-55 may be more appealing for users with limited space.
Installation and Compatibility
Both the ID-COOLING IS-55 and Thermalright AXP120-X67 are designed for easy installation. The IS-55 supports a range of Intel and AMD sockets, making it a versatile choice for many builds. Its compact size allows for straightforward installation, particularly in smaller cases where space is at a premium.
The AXP120-X67 also offers broad compatibility with various Intel and AMD sockets, including some of the latest models. The inclusion of metal fasteners and a focus on installation efficiency makes it user-friendly. While both products are compatible with numerous systems, the choice may come down to the specific socket required for the user's CPU.
Noise Levels
Noise levels are a crucial factor for many users, especially for those who prioritize a quiet computing experience. The ID-COOLING IS-55 operates at a noise level ranging from 13.8 to 31.2 dB(A), making it one of the quieter options available. This low noise level is particularly advantageous for users who build HTPCs or gaming rigs focused on silence.
Conversely, the Thermalright AXP120-X67 operates at a maximum noise level of 26.1 dB(A). While it is slightly louder than the IS-55, it still maintains a relatively quiet operation, making it suitable for a variety of use cases. For users who are sensitive to noise, the IS-55 may be the better option.
Price Comparison
The ID-COOLING IS-55 is priced at $39.99, while the Thermalright AXP120-X67 is more budget-friendly at $27.99. This makes the AXP120-X67 approximately 30% cheaper than the IS-55. For users looking to save money without sacrificing too much performance, the AXP120-X67 offers a compelling option. However, the price difference may be justified for those who require the specific features and design of the IS-55.
Which should you buy?
Choosing between the ID-COOLING IS-55 and the Thermalright AXP120-X67 ultimately depends on your specific needs and build preferences. If you're looking for a cooler that offers slightly better airflow, advanced techniques for heat management, and robust build quality, the AXP120-X67 is a solid choice at a lower price point. However, if you require a more compact cooler that operates at a quieter noise level, the IS-55 may be the better fit for your specific use case. Consider your system’s compatibility, budget, and cooling requirements to make the best decision.
