Common questions
Questions before you buy
Does the Ryzen 7 9800X3D require liquid cooling?
AMD does not require a specific liquid cooler. Choose a compatible solution and account for case airflow and workload.
Will every AM5 cooler fit my motherboard?
Socket support alone does not guarantee physical fit. Check the mounting kit, RAM height, board layout and case clearance.
How tall is the Noctua NH-D15 G2?
Noctua lists 168 mm with fans. Compare that with the CPU-cooler limit in your case documentation.
Is a shorter air cooler enough for gaming?
Height does not determine thermal performance by itself. Compare independent tests under workloads and noise levels similar to your use.
