Then why shouldn't tablets, or phones?

  I feel adding fans to a tablet or phone would somewhat defeat the goal of a small, portable computing device as fans need space. We'll always have the tradeoff between computing power and size, and tablets and phones favor the size side.

  Well, for starters, tablets and phones aren't generally equipped with connectors and cables that can supply enough power. Charging over USB limits you to 25W at most, but laptops generally come with power bricks to supply two or three times that, and desktop-replacement notebooks go much higher than that.
