    Crosshair VIII Dark Hero chipset repaste

    Dear forum,

    I've got a Dark Hero coming in soon. With the big passive chipset cooler, would you recommend removing the thermal pad and applying some quality thermal paste instead?

    I've been doing that in the past with the actively cooled mainboards (AORUS X570 Pro and MSI 570 Unify) with great success.

    Has anyone repasted their chipset coolers on a C8DH?


    Best regards

    TL;DR: Don't do it or get a replacement thermal pad, _not_ thermal paste!

    OK, I've just tried it, so here's the deal:
    The gap between the cooler and the chip is massive compared to the ones I've encountered on MSI X570 Tomahawk and X570 AORUS Pro, which really benefited from removing the thermal pad and replacing it with a good thermal paste.

    Not so on the C8DH. Repasted it with enough paste, until it made contact (checked by attaching and detaching the heatsink).

    Idle temps: 60-68°C and climbing (with zero fan GPU covering the whole thing)

    That seemed a little high.

    Just redid the setup and replaced the only slightly damaged original thermal pad:
    Idle temps: steady at 60-62°C
