Thanks for the chart. It is a great visual for what I already have in a spread sheet. Nice work!

But... it does not answer the question about static head pressure. Fans with a higher pressure are more capable of forcing air through dense cooling fins.

Air flow changes with the resistance of the load (fin density). A fan that moves 113 cfm in open air, may not move anywhere close to that volume when faced with an array of dense cooling fins.

On published tests, the fans that do the best in dense coolers are those with the highest static head pressure. This usually goes hand-in-hand with a thicker depth (i.e 38mm vs. 20mm).
