Cool to the core
Effective cooling is extremely important, even at stock speeds. That is why the Prime X299-A II allows consolidated cooling control of the entire system, even for the most hardcore rigs. It comes equipped with onboard heatsinks, an array of fan headers, and options for water pump or AIO headers.
Two M.2 slots are covered by heatsinks to combat temperature-induced throttling that can affect performance during heavy, sustained storage loads.
Tune it your way
Comprehensive controls form the foundation of the ASUS Prime series. The Prime X299-A II packs flexible tools to tune every aspect of your system to deliver the performance that you desire.
ASUS AI Overclocking makes automatic tuning faster and smarter than ever before. Available in Windows or directly through the UEFI, it profiles the CPU and cooling to predict the optimal configuration for each individual system.
