How to make the orcs meet these biological standards?

This is loosely linked to my nature Mage questions. In my fantasy world I want a race of Orcs. These are the characteristics they have to have:

• Stand between 6 and 7 feet tall

• Have crude weapons

• Reproduce quickly

• Reach Sexual maturity at age five and mental maturity at age 15

• Live a maximum of 25 years

• Have mindset of 15 year old human children

• unable to wield magic

How fast would the cells of these orcs have to grow and divide to reach these growth rates and reduce mental capacity to that of a fifteen year old human child? How realistic would this be to a reader?

Note that while there is magic in my world, I want a little handwavium used here as possible. Please try to include known biological processes and cell growth rates as a basis for your answer.
