I was always under the impression that they wre pretty much the same chips with binning depending on core strength and cache strength. If I'm running a lower vcore should the tenps also not be lower?
That's not how it works. It's the actual speed (frequency)of the CPU. So even though you're at a lower vcore the frequency is higher. So therefore per second, it's doing more. And since it's doing more it's going to get hotter.
I ran into a similar thing with my Opteron 180. I could extract an extra 500MHz out of it with no voltage increase, but since it was running @ 2900 instead of 2400MHz it ran hotter.
It basically boils down to how clock cycles the CPU churns in a given amount of time. And so the more cycles it does per, lets say, second will determine it's heat output.
And isn't the 965 a higher wattage CPU than the 720? I could've swore it was.
