LN2 cooling VS stock is an extreme case, so I can see having a measurable effect on voltage requirements.
Big differences, big results. Smaller differences, smaller results.... BUT THE PATTERN HOLDS.

Prime95 test 1 and 2 would pass (well 1 hour each during this testing phase) and those gave me the highest temp reading.
But it was the third test, the one that involve main memory, that would randomly fail hard.
You *wouldn't* know if heat was the cause, because heat is NOT alone! This is the point I keep making! If the heat is higher, the chip is less stable, even at the same clocks and voltages. If you then INCREASE voltages, you have COMPOUNDED the heat increase!
This is usually where most overclocking projects end, people say "It just wouldn't get stable, no matter what voltage I gave it". More voltage does two things. It can make the signalling inside the chip "louder" and thus get a borderline signal through, or it increases heat. When OCing you want the first effect, but want to avoid the second. That's why you shouldn't start by putting your CPU at the max voltages you'll allow and backing down. If you want to OC correctly, you start slowly increasing the clocks until things become borderline unstable, and then you try increasing the voltage. If that doesn't work, sometimes you should actually DECREASE the voltage. In particular, "hot bins" like the 4790K I'm running now, they often ship with voltages higher than they really need, though this is much less common than it used to be. By using a better cooler, or more controlled environmental temperatures, you can decrease voltages below stock and still run stable.
At any point, you can say "I don't want to listen to you anymore" and I'll go away, but telling me I'm wrong won't do that. I've done a lot of tweaking and clocking and tinkering and I'm telling you straight; Using an underperforming cooler while overclocking WILL have a serious impact on the clocks you can achieve and the voltages you can use. The stock Intel coolers are the very definition of "barely adequate", and running at any clocks or volts higher than stock while using the Intel cooler is counterproductive.
