Why would the saw run cooler if there is more voltage to the saw?

Because the current is less, and it's current that generates heat, not
voltage.

Oh, really?

Which generates more heat:
1) a 60-watt lightbulb (designed for 120V) running at 120v
2) a 60-watt lightbulb (designed for 240V) running at 240v

Note that #1 is drawing 1/2 amp, and #2 is drawing only 1/4 amp.

"Watts is watts", applies -- It doesn't matter how they're produced.

I agree that "Watts is watts" but wouldn't the temperature of the
conductor(s) come into play since the resistance of a wire increases as the
temperature rises?
