Overview of the Products

When considering CPU coolers, the be quiet! Dark Rock Pro 5 and the Thermalright AXP90 X36 provide distinct solutions for different needs. The Dark Rock Pro 5 is priced at $84.90, while the AXP90 X36 is significantly more economical at $20.39. This price difference of about 75% reflects their targeted user bases; the Dark Rock Pro 5 is designed for high-performance setups, whereas the AXP90 X36 caters to compact builds.

Design and Build Quality

The design of the be quiet! Dark Rock Pro 5 emphasizes both functionality and aesthetics. It features a distinctive black coating with ceramic particles, adding to its premium feel. The cooler is built with 7 high-performance copper heat pipes that ensure efficient heat dissipation. In contrast, the Thermalright AXP90 X36 is a low-profile cooler with a total height of only 36mm, making it ideal for compact ITX cases. While both coolers boast excellent build quality, the Dark Rock Pro 5 targets users who prioritize performance alongside aesthetics, while the AXP90 X36 is functional for those with space constraints.

Cooling Performance

Cooling performance is where the be quiet! Dark Rock Pro 5 excels, capable of handling peak CPU performance even in heavily overclocked systems. It features two Silent Wings PWM fans, which can reach a maximum speed of 2000 revolutions per minute (r/min) in Performance Mode. This allows it to maintain low temperatures under stress. The Thermalright AXP90 X36, while not as powerful, is designed for lower thermal resistance and operates at a noise level of just 22.4 DBA. For users with less demanding setups, the AXP90 X36 offers sufficient cooling, but it lacks the robust performance of the Dark Rock Pro 5.

Noise Levels

Noise levels are a critical factor in selecting a CPU cooler, and the be quiet! Dark Rock Pro 5 is designed to operate quietly, with a maximum fan speed of 1500 r/min in Quiet Mode. This makes it suitable for users who desire a silent working environment. The Thermalright AXP90 X36, however, also boasts a low noise level of 22.4 DBA, making it a good choice for compact builds where sound control is essential. While both coolers are relatively quiet, the Dark Rock Pro 5 offers more versatility with its dual modes, allowing users to choose between performance and quiet operation.

Compatibility

Compatibility is an essential consideration when choosing a CPU cooler. The be quiet! Dark Rock Pro 5 is compatible with a wide range of sockets, making it versatile for various builds. It is designed to work seamlessly with high-end CPUs, including those from Intel and AMD. The Thermalright AXP90 X36 also offers good compatibility, supporting Intel sockets 115X/1200 and AMD AM4/AM5. However, its low-profile design primarily targets smaller setups, which might limit its appeal for users with larger cases looking for high-performance cooling.

Installation Process

The installation process can greatly influence user experience, and the be quiet! Dark Rock Pro 5 provides a straightforward installation method with a pre-installed mounting bridge and fixing screws that match its design. The detachable mesh top cover simplifies access to the fans and heatsink. On the other hand, the Thermalright AXP90 X36 features an all-metal platform with a backplate fastener that aids in its installation. While both coolers are designed for ease of use, the Dark Rock Pro 5’s design may offer a slight edge in user-friendliness, particularly for first-time builders.

Price and Value

Price is a significant differentiator between the two coolers. The be quiet! Dark Rock Pro 5 retails for $84.90, while the Thermalright AXP90 X36 is priced at just $20.39. This substantial price difference of approximately 75% reflects the performance and features offered by each cooler. Users looking for a high-quality, performance-oriented cooler will find value in the Dark Rock Pro 5, while those on a tighter budget or with less demanding cooling needs will appreciate the affordability of the AXP90 X36.

Which should you buy?
