FAQ
Is liquid cooling mandatory for the 5800X3D?
No, high-end air coolers are perfectly capable of handling this chip, though AIOs offer better clearance for RAM and a cleaner aesthetic in smaller cases
Why does this CPU run hotter than others?
The 3D V-Cache layer sits on top of the silicon, acting as a thermal insulator that makes heat extraction from the core significantly more difficult
Does RAM clearance matter for air coolers?
Yes, large dual-tower air coolers often overhang DIMM slots, so verify your memory height before purchasing to avoid physical interference during installation
