No.
At least, not without further context.
Emotions are natural responses to certain situations. But if anger or any emotion occurs inappropriately, or at an inappropriate level, it might indicate some sort of mental health problem (might not be serious). Not even intelligence related necessarily.
If you're getting angry when trying to learn or in response to new information, I suppose that could be a sign of low intelligence. Frustration with failure is quite normal though.
