Overview of the Products
The ID-COOLING IS-55 Black CPU Cooler and the Thermalright AXP90-X53 White Low Profile ITX CPU Air Cooler are both excellent choices for those seeking low-profile cooling solutions. The ID-COOLING cooler is priced at $39.99, while the Thermalright option comes in significantly lower at $19.39, making it about 51% cheaper. This difference could be a significant factor for budget-conscious consumers looking to maximize their cooling performance without overspending.
Heat Dissipation Capabilities
The ID-COOLING IS-55 features five heat pipes and a 120mm PWM fan, ensuring excellent heat transfer from the CPU. The low-profile design allows for effective cooling, even in compact builds. In contrast, the Thermalright AXP90-X53 utilizes four pure copper heat pipes and a 92mm PWM fan. While both coolers are designed for efficient heat dissipation, the ID-COOLING's larger fan and additional heat pipe may provide slightly better performance under heavy loads, especially in systems with higher thermal output.
Design and Size
The ID-COOLING IS-55 has a total height of 57mm, making it a compact option suitable for HTPCs and small form factor builds. The Thermalright AXP90-X53 is even more compact at 53mm in height, offering a slight edge in low-profile design. This difference in height may allow the AXP90-X53 to fit into tighter spaces or configurations where height clearance is critical. Both designs prioritize compatibility with memory modules, ensuring they do not obstruct RAM slots.
Fan Performance and Noise Levels
The fan in the ID-COOLING IS-55 operates with a noise level ranging from 13.8 to 31.2 dB(A), delivering a maximum air flow of 54.6 CFM. This allows for quiet operation while maintaining effective cooling performance. On the other hand, the Thermalright AXP90-X53's fan operates at a maximum noise level of 22.4 dB(A) with an air volume of 42.58 CFM. Although the AXP90-X53 is quieter, the ID-COOLING cooler potentially offers a higher cooling capacity due to its larger airflow, making it a better choice for users who prioritize performance over absolute silence.
Compatibility with CPU Sockets
Both coolers boast broad compatibility with various CPU sockets. The ID-COOLING IS-55 supports Intel LGA 1851/1700/1200/1151/1150/1155/1156 and AMD AM5/AM4. The Thermalright AXP90-X53 covers the same Intel sockets as well as AMD AM4/AM5, making them similarly versatile. This compatibility enables users to install either cooler on a wide range of modern systems, providing flexibility for different builds.
Installation Ease
The ID-COOLING IS-55 is designed for straightforward installation, particularly in Mini-ITX motherboards, ensuring users can set it up without facing significant obstacles. Meanwhile, the Thermalright AXP90-X53 also emphasizes ease of installation, providing metal mounting fasteners for various platforms. Users may find the installation process for both coolers to be relatively hassle-free, but the AXP90-X53's inclusion of installation videos may enhance the experience for less experienced builders.
Price Comparison
The price difference between the two coolers is significant, with the ID-COOLING IS-55 retailing at $39.99 and the Thermalright AXP90-X53 at just $19.39. This makes the AXP90-X53 about 51% less expensive than its counterpart. For those on a tight budget, the lower price of the Thermalright cooler may be appealing, especially for users whose cooling needs are moderate and who may not require the enhanced performance of the ID-COOLING model.
Which should you buy?
Ultimately, choosing between the ID-COOLING IS-55 and the Thermalright AXP90-X53 comes down to specific user needs and preferences. If you prioritize cooling performance and are willing to invest a bit more, the ID-COOLING IS-55 may be the better option with its additional heat pipes and higher airflow. However, if budget is your primary concern and your cooling requirements are less demanding, the Thermalright AXP90-X53 offers excellent value for its price.
