vcore..
is 1.75 V. if you are REALLY having trouble you could either: A, run it undervolted (-.1 or so) or B, do what I did and add a 7000 rpm 60MM YS Tech fan to your HSF and a 120MM AC powered fan to your case, sucking cold air onto your cpu. Sounds like a jet engine, but at 1.6, its worth it to me.
