    COOLING

    A comprehensive cooling solution features carefully-designed heatsinks with the perfect balance of surface mass and air flow. 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.
    Heatsinks

    Cooling Heatsinks
    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.

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

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

    DIMM.2 heatsinks
    The ROG DIMM.2 module now passively cools M.2 drives with metal heatsinks that also keep your build looking clean.

    High-conductivity thermal pad
    The high-quality thermal pad improves overall heat transfer from the system by bridging the heat generated by the power stages to the heatsink.

    Extended VRM heatsink
    The extended heatsink increases thermal mass to deal with the additional heat generated by high power consumption.

    Chipset heatsink
    A dedicated chipset heatsink draws heat away to maintain optimum operating temperatures.
    Headers

    Cooler by design

    Maximus XII Apex features the most comprehensive cooling options ever.


    Multiple temperature sources

    Each header can be set to monitor and react to three user-configurable thermal sensors for workload-based cooling. And all settings can be easily managed by Fan Xpert 4 or UEFI.
