This is an excellent guide! Got the Chili pad a couple weeks ago, and it is great. Wife is not so happy with it because it is to loud. Looking at the two fans mentioned in the original article and the comments, it appears the “be quiet! Pure Wings 2 92mm, BL045, Cooling Fan” is the one to choose. My only concern is the CFM for the be quiet fan (33.15 cfm) may not be enough. Does anyone know what the CFM was for the original fan?
