Compatibility and related parts
At 165 mm tall, this cooler needs a case with at least that much CPU cooler clearance, so check the spec sheet of your chosen PC case before ordering. Confirm your CPU socket is on the supported list (AM5, AM4, LGA1851, LGA1700, LGA1200, LGA115x) when picking from our processors (CPUs), and make sure your motherboard has a 4-pin PWM fan header plus a 9-pin header or spare USB port for the digital connector. The PC builder checks compatibility for you, and you can add fresh thermal paste and pads for remounts.
