It depends on what type of cooling you have. The lower, the better though.
The CPU will last longer, the lower you keep the voltages.
Actually, the voltage have everything to do with it. 65nm's can take alot more abuse because of that extra 20nm between transistors. However, the 45nm's are pretty tough too because of the new cadmium transistors they are using.
And I think the e7400 C2D is a 65nm?
65nm basically maxes out at 1.50v-1.51v. I've heard of people going above it, but it's pretty dangerous.
And the word on 45nm (at least quads) is 1.39v (For the Yorkfields, at least.)
