First thought would normally be with the QRs rather than the crown race. Could be not night enough, or just not be interfacing well with the drop outs.
QR as in quick release? From the wheel's hub? They're alloy on the minimal. Although it's hard to see where the noise comes from in the head tube area, it's definitely coming from there.
