The Thermalright AXP-90 X53 Black is a compact CPU air cooler designed for efficient processor cooling in space-constrained systems. With a total height of just 53 mm, this flat cooler easily fits into small form factor cases while still providing reliable thermal performance. The cooler features four copper heat pipes that efficiently transfer heat from the CPU to the aluminum fin stack, where a 92 mm PWM-controlled fan dissipates the heat. This fan operates at a maximum noise level of 22.4 dBA, ensuring quiet operation during normal use, with an airflow of up to 42.58 CFM and a static pressure of 1.33 mmH₂O. The PWM control allows the fan speed to automatically adjust between 0 and 2700 RPM based on CPU temperature, optimizing the balance between cooling performance and noise level. Compatibility includes AMD Socket AM4 and AM5 platforms as well as Intel Socket LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, and LGA1700. The fully black surface gives it a clean, professional appearance that fits well into various system configurations. The package includes thermal paste for immediate installation. This successor model to the previous AXP-90 versions maintains the same compact footprint while offering improved cooling efficiency for modern processors in limited space environments.
