AC vs battery power temperatures

I'm not sure if anyone help has noticed this, but when im on battery power, the laptop stays very cool and never turns on the fan. However, when i run on AC power, the temperatures rise just enough to toggle the fan on and off ever 5 mins or so. I think it is great that this laptop runs so cool either way, but i was wondering how i can get the computer to run as cool as it does on battery power when on AC power.

I know the different settings between passive cooling and active cooling, but i can feel and measure the difference in temperatures. So it is not as if the computer on battery is running the same temp but the fans arent kicking on. The laptop actually runs much cooler.

Things that i have already tried are matching the power profiles of both "when on battery" and "when plugged in" and also the intel graphics power settings "when on battery" and "when plugged in". Are there any other ideas to what would cause the difference in temperatures between being on battery and being plugged into an outlet?

Thanks.

 

Im guessing when its plugged in it takes in more energy, or heat.

 

Also some of the power plans should have system cooling policy that sets it to passive when on battery. That means less fan and less power consumption.

 

I completely understand the passive vs active cooling, but it is more like the actually heat being produced inside the computer. Im assuming it is more of what Blab said about not really trying to conserve energy therefore the laptop will just produce more heat. I'm just trying to find a way to get the low amount of heat produced on battery to also happen when on AC power.

 

Sorry, I didn't catch that you'd mentioned the cooling policy in your original post.
