Some of the definitions of intelligence say:
- Merriam-Webster: the ability to learn or understand things or to deal with new or difficult situations; the ability to learn or understand or to deal with new or trying situations.

And emotions are defined as:

Daniel Goleman brought the attention of a wide audience to the term “emotional intelligence” with his book of the same name back in 1995. Emotional intelligence is the ability to understand and manage your own emotions, and those of the people around you. For leaders, having empathy is critical to lead a successful team or organization as it enables the ability to put themselves in someone else's situation. For scientists intelligence is a crucial parameter. They have to think and invent. They do so mostly in their heads. Is this high level of expertise a useful tool in leading people? The same can be questioned by “Is the leader the smartest person in the room?”
Studies by Fiedler show that when under stress, intelligent leaders’ attention “resources”, that could otherwise be devoted to planning, problem solving and creative judgment, are instead focused on worries over possible failure, crises of self-efficacy, and evaluation anxiety. Is this what a leadership is about?
I think the issue is not so duo polar: intelligence vs. emotions! It has to have much more in it and therefore I would argue that for a “perfect leader” some intermediate path is the key to success: having both, intelligence and emotions.
