The NF-P12 that c/w the above cooler, why does Noctua use a 12 cm fan on that end but a 14 cm fan on the other? Why not swap the 12 cm w/ the 14 cm? And for that matter, what if some1 swap out the 12 cm to a 14 cm?
I bet the 120 was done on the outside for RAM clearance issues (the 140 would probably hit even regular sized RAM), and the 140 was done due to better noise/airflow ratios. The 140 on the end would probably work if you were using the low profile Samsungs.
