depends how fasts it is moving - but it's all moving at the same speed. The last chip will get less cooling than the first chip, proportional to the amount of cooling the previous chips received. Delta T doesn't lie.
Whether it's significant or not, I can't know - but you want it to be significant, otherwise it's less efficient.
