With the addition of fan headers, the onboard cooling of Maximus XII Apex has more than enough capacity for specialization, maintaining system stability under any condition.

  • Heatsink
  • Headers

Cooling Heatsinks

  1. VRM and I/O heatsink

    A high mass, finned heatsink is connected to the I/O cover via a heat pipe, providing an expansive surface area for efficient heat dissipation.

  2. Large‑diameter heatpipe

    The U-shaped design provides rapid and even heat transfer from the VRM to the extended VRM heatsink.

  3. Aluminum heatsink cover

    The heatsink cover is crafted from pure aluminum to efficiently cool the onboard M.2 drive.
