[QUOTE="NAV33N, post: 1198463, member: 26344"] Fan Configuration for CM 690 or CM 690 II. Front Fan - Intake Top Fans - Exhaust Side Panel Fans - Intake Bottom Fan(s) - Intake Rear Fan - Exhaust 80mm CPU Fan Behind Motherboard - Intake If Intake Fans have more CFM than exhaust ones then total air intake in the system is more than total air exhaust. in this case temps are higher. If Intake Fans have less CFM than exhaust ones then total air intake in the system is less than total air exhaust. so,automatically air is being sucked into the case to level the negative pressure. in this case temps are lower. about CM 690 II & NZXT Tempest EVO,i believe that both are very good cases & it's the matter of perception who like or prefers the look of which case. although IMO i feel that the build quality of CM690 is better than Tempest (i'm not comparing new versions) but i'm not sure about the current versions as they are updated. but i do like that Tempest EVO comes with all fans which CM 690 II doesn't.
