My friend just came over so he could transfer some 4gigs of MP3 to my PC (via network). We have the same Inwin case but his has a lot more "extras" to it. Like 4 80mm Deltas that flow 80cfm and screams at 53db. Yes, thats FOUR of them, one at the front, at the rear, one on top of his Swiftech MC462 and one as a blow hole on top of his case. To make matters worse, the side of his case has TWO of this monster YStech 120mm fan that blows 130cfm at 45db! I thought my Kirby G4 was louder but this PC is giving it a run for the money..😛
