Ah, I see.

Well, if the fan is the same size and style and everything, it should work just fine. If it can cool the faster of the two processors it can cool the slower. =) (Unless of course the faster one has some special low voltage magic voodoo that keeps it from getting as hot, but even then the fans don't have big variances in terms of speed and air moved)
