I was looking at the red led fans that are offered by Cooler master and I'm wondering which fan will be the best for cooling my system. I currently have the 140mm fan and wonder if putting the 120mm would be better because of the higher CFMs, or is the larger 140mm better? Here are the fans descriptions.

Thank you for the info. The question I'm trying to answer is would I be better off replacing the 140mm fans in the case in the front and top with the 120mm because of the better CFM air flow. So is the larger fan in MM better that the smaller fan with better CFM.
