I'm not an Intel user but I'd say mid-high 40s? The best way to get your temp down is to put a good cooler on it. And make sure you have at least two case fans, one intake and one exhaust. I'd also suggest a high quality thermal compound like Arctic Silver II.
The three coolers I'd recommend are: Alpha PAL6035, GlobalWin FOP32-1, or Taisol CGK760092.
