The provided data for the Thermalright AXP90 X36 Low Profile ITX does not explicitly list socket compatibility in the features, though it mentions compatibility with more small motherboards due to its height. Users verifying the Thermalright AXP90 X36 Low Profile ITX should confirm specific socket mounting hardware availability, whereas the Thermalright AXP90-X53 Full Cooper Low explicitly confirms support for current mainstream platforms.

Cooling Performance and Heatpipes

Both units utilize 4x6mm heatpipes, but the technology generation differs. The Thermalright AXP90-X53 Full Cooper Low uses standard AGHP heatpipes. The Thermalright AXP90 X36 Low Profile ITX adopts the 4th generation technology of AGHP upgrade. This upgrade is designed to solve the inverse gravity effect caused by vertical or horizontal orientation. With 2 soldered heat pipe fins, the heat transfer efficiency of the Thermalright AXP90 X36 Low Profile ITX heatsink is claimed to be doubled. This suggests a potential advantage in thermal performance for the Thermalright AXP90 X36 Low Profile ITX in varied case orientations.

Fan Specifications and Noise

Fan control mechanisms vary between the two models. The Thermalright AXP90-X53 Full Cooper Low operates on a 12V voltage with a maximum current of 0.2A. It specifies a noise level of ≤22.4DBA. The Thermalright AXP90 X36 Low Profile ITX is matched with a TL-9015R 92mm PWM fan. This allows for automatic temperature control and ultra-quiet operation. While the Thermalright AXP90-X53 Full Cooper Low provides a specific decibel rating, the PWM capability of the Thermalright AXP90 X36 Low Profile ITX offers dynamic adjustment based on thermal load, which can improve acoustic efficiency during idle periods.

Dimensions and Case Clearance

Physical dimensions are vital for ITX and HTPC builds. The Thermalright AXP90-X53 Full Cooper Low is described as a compact cooler with a total height of 36mm. This low profile is ideal for cases with strict clearance limitations. The Thermalright AXP90 X36 Low Profile ITX has a total cooler height of 53mm and a cooling size of 94.5×95×53mm. While the Thermalright AXP90 X36 Low Profile ITX is taller, it is still considered ideal for HTPC and ITX models without memory limitation worries. The Thermalright AXP90-X53 Full Cooper Low offers a lower vertical footprint according to the provided specifications, potentially fitting into tighter chassis configurations.

Installation and Maintenance

Installation features include back plate fasteners for the Thermalright AXP90-X53 Full Cooper Low, ensuring secure mounting on the motherboard. The all-metal platform contributes to durability during installation. The Thermalright AXP90 X36 Low Profile ITX focuses on optimized details to reduce wind damage, which may simplify airflow management within the case. Maintenance for both units involves standard dust removal from the fins. The nickel plating on the Thermalright AXP90-X53 Full Cooper Low may offer additional resistance to environmental factors, while the anti-oxidation process on the Thermalright AXP90 X36 Low Profile ITX protects the copper base from degradation over time.

Price and Value

Pricing distinguishes these two options significantly. The Thermalright AXP90-X53 Full Cooper Low is listed at $20.39, making it a budget-friendly option for builders. The Thermalright AXP90 X36 Low Profile ITX is priced at $35.90. The higher cost of the Thermalright AXP90 X36 Low Profile ITX reflects its PWM fan, 4th generation heatpipes, and detailed construction specifications. For users prioritizing cost efficiency, the Thermalright AXP90-X53 Full Cooper Low provides essential cooling features at a lower entry point. However, the Thermalright AXP90 X36 Low Profile ITX offers enhanced technology that may justify the premium for performance-focused small form factor builds.

Which one should you buy?

Choosing between these coolers depends on specific build requirements. If budget and minimum height are the primary concerns, the Thermalright AXP90-X53 Full Cooper Low is the logical choice with its 36mm profile and lower price. It suits builds where every millimeter counts and socket support for Intel 115X/1200 or AMD AM4/AM5 is required. If performance technology and fan control are priorities, the Thermalright AXP90 X36 Low Profile ITX is superior. Its PWM fan, 4th generation AGHP, and specified airflow make it better suited for users seeking automated thermal management. Ultimately, the Thermalright AXP90 X36 Low Profile ITX wins on technical features, while the Thermalright AXP90-X53 Full Cooper Low wins on value and clearance.
