when i still had my board, i didn't recall the northbridge being very loud. I had a very loud 120mm case fan, but when i turned it off, i could barely hear anything else. Still, i've heard lots of people say it is pretty loud. Unfortunately, due to the placement of the northbridge, a small, active cooler had to be used to avoid interfering with an SLI setup. If you aren't planning on running 2 graphics cards, or want to use the secondary slot for a small X300 or something to drive an extra monitor, then you can throw on a taller passive heatsink. I've heard that Zalman makes some great northbridge coolers that are passive, i.e. totally silent, and i don't think they are very expensive.
BTW, has anyone used the Vantec Stealth 120mm case fan? I was looking at it, and I thought it might be just the ticket to quiet down my loud system, but i'm not sure how well it performs. I'm running 2 80mm fans in the front, a 120mm in the rear, and my 3 fan Vantec Stealth VAN-520A PSU also in the rear. I figured that 53CFM for the rear fan should provide enough airflow, but i'm not sure. Also, how quiet is it? I got some generic 120mm fan, and it sounds like a freakin jet taking off!
