Price Comparison
When it comes to price, the Thermalright AXP90 X36 Black is significantly more affordable at C$26.90 compared to the upHere H45K6, which retails for C$49.99. The price difference of C$23.09 might be a deciding factor for budget-conscious consumers looking for value in their CPU cooling solutions. While both products offer unique features, the lower price of the AXP90 X36 Black could appeal to those who want effective cooling without breaking the bank.
Design and Build Quality
In terms of design, the upHere H45K6 boasts a compact 45mm height, making it particularly suited for Mini ITX cases where space is at a premium. This low-profile design allows for seamless integration into small-form-factor builds. On the other hand, the Thermalright AXP90 X36 Black does not specify its height, but it is generally known for its robust build quality typical of Thermalright products. The choice between these two may hinge on whether you require a specifically low-profile cooler or prefer a sturdier build that may occupy more space.
Cooling Performance
The upHere H45K6 features six heat pipes designed to manage a thermal design power (TDP) of 150W, which is quite impressive for maintaining stable temperatures under load. This cooler’s efficient thermal transfer is complemented by a high-airflow 90mm fan that operates quietly at ≤27 dB(A). In contrast, the Thermalright AXP90 X36 Black does not provide specific details on its cooling capacity or performance metrics, making it less clear how it stacks up against the upHere model. For users prioritizing cooling efficiency, the detailed specifications of the upHere H45K6 may provide a compelling advantage.
Noise Levels
The upHere H45K6 is engineered for quiet operation with its PWM fan that adjusts between 800-2800 RPM, ensuring that it maintains a noise level of ≤27 dB(A). This makes it an excellent choice for users aiming to build a silent system. Unfortunately, the Thermalright AXP90 X36 Black does not provide any information regarding its noise levels, leaving potential buyers in the dark regarding how it might perform in quieter environments. If noise levels are a primary concern, the specified performance of the upHere H45K6 gives it an edge.
Compatibility
Compatibility is a strong suit for the upHere H45K6, which has been designed to avoid interference with RAM, motherboard heatsinks, and other critical components. It supports a wide range of sockets, including Intel LGA 1851/1700/115x/1200/2011/2066 and AMD AM5/AM4/AM3, making it versatile for various builds. The Thermalright AXP90 X36 Black does not provide specific compatibility details, which could lead to potential issues in fitting within certain system configurations. For users who want peace of mind regarding compatibility, the upHere H45K6 offers clear advantages.
Installation Process
The upHere H45K6 is designed for easy installation, boasting a tool-free setup that can be completed in under five minutes. This feature is especially beneficial for users who may not have extensive experience with CPU cooler installation. In contrast, there is no information available regarding the installation process for the Thermalright AXP90 X36 Black. If convenience and ease of installation are priorities, the straightforward setup of the upHere H45K6 may be more appealing.
Aesthetic Appeal
Aesthetically, both the Thermalright AXP90 X36 Black and the upHere H45K6 have unique designs that cater to different tastes. The Thermalright AXP90 X36 Black is likely to attract users who prefer a more traditional cooler look, while the upHere H45K6’s sleek and compact design may appeal to those focused on a modern, minimalist build. Ultimately, the choice in aesthetics will depend on personal preference and how each cooler fits within the overall theme of the user's setup.
Which should you buy?
Choosing between the Thermalright AXP90 X36 Black and the upHere H45K6 ultimately hinges on your specific needs and preferences. If budget is a primary concern, the AXP90 X36 Black offers a lower price point at C$26.90. However, if you prioritize performance, especially in terms of cooling efficiency, noise levels, and compatibility, the upHere H45K6 stands out with its robust features and proven performance metrics, albeit at a higher cost of C$49.99. For those building in tight spaces, the compact design of the H45K6 might be indispensable. Therefore, consider your priorities carefully when making your choice.
