Dimension comparison
Design and Size
When it comes to design and size, the upHere H45K6 takes the lead with its ultra-compact 45mm height. This low-profile design allows it to fit seamlessly into space-constrained Mini ITX cases without sacrificing performance. In contrast, the Thermalright AXP90 X53 has a slightly taller height of 53mm, which may limit its compatibility with ultra-compact builds. While both coolers are designed to fit in smaller cases, the 8mm difference in height could be a key factor for builders looking for maximum clearance.
Cooling Performance
Cooling performance is crucial for maintaining optimal CPU temperatures, especially under heavy workloads. The upHere H45K6 features six heat pipes that ensure efficient 150W TDP heat dissipation, making it well-suited for mainstream CPUs during sustained use. On the other hand, the Thermalright AXP90 X53 utilises four heat pipes with advanced AGHP technology to significantly improve heat transfer efficiency. While both coolers are capable of effective thermal management, the H45K6’s six heat pipes provide a greater overall cooling capacity.
Fan Technology
Fan technology plays a significant role in the overall effectiveness of CPU coolers. The upHere H45K6 is equipped with a 90mm PWM fan that operates quietly at a noise level of ≤27 dB(A). This makes it ideal for silent builds while still pushing 35.34 CFM of airflow. Conversely, the Thermalright AXP90 X53 uses a 92mm slim PWM fan capable of reaching up to 2700 RPM, but it does not specify the noise levels. While both fans are designed for high efficiency, the H45K6’s quieter performance may appeal more to users sensitive to noise.
Installation and Compatibility
Both coolers excel in installation and compatibility, but the upHere H45K6 offers a slight edge. It is engineered to avoid interference with RAM and other motherboard components, ensuring 100% memory clearance. This makes it particularly advantageous for builds with limited space. The Thermalright AXP90 X53, while compatible with a range of CPU sockets including Intel’s LGA1700 and AMD’s AM4/AM5, requires more intricate installation steps, especially if conflicts arise with the motherboard's backplane. For ease of installation, the upHere cooler may be the better choice.
Durability
Durability is a key consideration when investing in a CPU cooler. The upHere H45K6 boasts a fan lifespan of 40,000 hours, ensuring long-term reliability without a drop in performance. In comparison, the Thermalright AXP90 X53 features S-FDB bearings with an industrial service life of up to 20,000 hours. While both coolers are built to last, the upHere H45K6's longer lifespan provides an advantage, especially for users seeking a dependable cooling solution over time.
Price and Value
In terms of price, the Thermalright AXP90 X53 is more affordable at C$45.99, compared to the upHere H45K6, which retails for C$49.99. While the price difference is only C$4, the AXP90 X53 offers advanced cooling technology at a lower cost. However, considering the features and performance of the upHere H45K6, many users may find the extra investment worthwhile for its quieter operation, better compatibility, and enhanced durability.
Brand Reputation
Brand reputation can influence purchasing decisions, and both Thermalright and upHere have established themselves within the CPU cooling market. Thermalright has over 20 years of experience and is well-known for its innovative cooling solutions. UpHere, while newer, has quickly garnered attention for its effective design and performance in small form factors. Depending on user preference for brand loyalty, either cooler can represent a solid choice.
Which should you buy?
Choosing between the Thermalright AXP90 X53 and the upHere H45K6 ultimately depends on your specific needs. If you prioritise a lower price point and advanced heat transfer technology, the AXP90 X53 may be the better option. However, if you require a cooler that fits perfectly in tight spaces, offers quieter operation, and provides better overall durability, the upHere H45K6 stands out as the superior choice. Consider your build requirements and personal preferences to make the best decision.
