I have a watercooled workstation (don't ask), and one day I made it spin up the pump when the chips heat up. I believe it goes from 17% pwm to 18% whenever any chip is more than 15°C warmer than the water. Changes nothing, and you wouldn't set it up like that.

But the immediate frequency change is enough for me to anticipate a delayed reaction. "Oh, computer is computing. Reach for coffee."
