The old 120 hardly seemed like it was doing anything. All the pics are in this folder. I'm sure you can tell what I did when you see the pics, for example the red dots.. I was holding the cardboard outside the case and poked trough the outermost holes to get a perimeter..
New LED fan seems like push out ALOT more air, temps are doing a few degrees cooler, and we just turned off the AC today too.
Comment, question, whatever..
