    I think I found the source of the liquid @[email protected]. The thermal pad under the VRM heatsink has begun to liquefy into oily substance. This substance appears to have gone to the underside of the board through the vias around the VRM and discolored itself.

    Some rubbing with isopropyl alcohol and it’s almost gone:

    Perhaps there’s still life left in this board if used with an older chip.
