I don't think it really matters, Just blow the hot air from the CPU at one of the two exhaust fans in your case. The 140mm fan would probably do a better job, so I think if I were to chose that would be my pick, but as long as the CPU cooler isn't blowing air down or towards your drives I don't think it will matter much.
