The bios may turn off speedstep and other power saving measures while the laptop is on AC power. Less power consumed = less heat generated = less heat to get rid of.

You might look in your bios to see if there are any options for when speedstep and such work.

EDIT:
It's worth noting that all power used in your laptop is turned into heat, with the very small exception of the light produced by the backlight in your screen. All the rest of it turns into heat.
Charging batteries produces heat, and if the batteries are near the chip that may change how much the chip heatsink and heat tube can get rid of passively.
