Fisher's test conditions on the marginal totals being fixed at the observed values. The chi square-squared test does not. Under the assumption of fixed marginals, Fisher's test is exact. TheThe chi square-squared test is still an asymptotic approximation, even under your case where the Cochran rules hold.
