Digital Downloads PS4

Out of curiousity and because I could not find anything saying so (I'm also not too savvy with these sorts of things) would the PS4 run cooler if one were to purchase their games and play them digitally opposed to physically? Or would the constant reading from the HDD create as much heat as reading the actual discs themselves?

Well as far as I know all disc based games have to be installed to the harddrive anyway and not just a small amount of data. The entire game data has to be installed to the harddrive but you still need the disc inside the PS4 to run the game. So it probably runs the game off the harddrive anyway.

I guess we are going to have to figure out a way to cool this thing down a bit.
