Pumps always make some heat. Most of the heat comes off of the motor, but the friction of the impeller will make a negligibly small amount of heat, too.

If you run the pump inline, the vast majority of pump heat is dissipated through the pump's housing. It will be dissipated into the air in the case. The small amount of heat made by the impeller will obviously always end up in the water.

Running the pump submerged in a reservoir will capture all of the heat of the pump with the water. there is nowhere else for the heat to go.

Adding heatsinks to the side of an inline pump that has healthy airflow might help the pump run cooler, but it is doubtful that the water temperature will change any measurable amount.

What kind of pump are you using?
