I've had two SP10s in my custody for hosting since about July, and this has happened to me three times (twice on one machine). One of them blew a VRM in January when the intake temps were about 14C. That grey bead to the uppper right corner is the only connection between your VRM/bank and the 12V rail, which means if you're worried just remove it and thew hole burnt section is now electrically cut off. Both my SP10s still work at reduced capacity.
