Zalman's ZM-NB47J is a fully adjustable Northbridge heatsink. It comes with 2 springs. Because the links aren't permanently attached you can adjust them so that the heatsink fits onto the motherboard with maximum clearance.
The 37mm square unit is 47mm high with a plethora of pins placed perfectly to provide a large amount of surface area to dissipate heat. This makes a fan unnecessary, giving you all the peace (or maybe war) and quiet you need. Zalman's ZM-NB47J is a cool customer to keep your case from cookin'!

This user purchased this item from Newegg
Pros: Lowered temps by about 8 degrees celcius.
Installation so easy "a caveman could do it."
Nice tidy footprint.
Got rid of my very noisy fan that was on its last leg.
Newegg delivered in two days, no problem.
Cons: As with replacing a cpu heatsink, it takes a couple weeks for thermal paste to "set," so don't expect lower temps immediately.
Consider tall profile before purchasing-- depending on where you intend to put it and what may be over that area (side panel fan, extra long graphics card, etc.).
Not for mobos with anchors for hooks around chipset. Designed only for chipsets with plastic "push-through" anchors with springs (comes with 4 in pkg).
Other Thoughts: when assembling for installation, go ahead and loosely screw (less than hand-tight) the small anchors onto the heatsink. Don't apply paste to heatsink or chipset yet. set on chipset as if installing and carefully tighten the anchors after eyeballing where they need to be. loosen slightly to make small adjustments and tighten again. Instructions are down and dirty and don't include these kind of remarks. Made install very very easy.

Good cooler

This user purchased this item from Newegg
Pros: Have had for over a year on my a8n sli deluxe board cooling a athlon 3200@ 2700. Keeps temps down very well.
Cons: I just installed a 8800gts 320mb card into my rig and the zalman cooler was too big and in the way. I ended up sawing half the metal fins off at the base and the 8800gts fit right in. Temps are still the same! Saved me some money because I didn't have to buy a new cooler.
Other Thoughts: Cant beat that price.

This user purchased this item from Newegg
Pros: Heatsink works great and has helped improve my computer's performance since the northbridge is able to operate at cooler temps.
Cons: The thermal compound took some time to settle at first causing my northbridge to constantly overheat which caused my computer to crash a lot to the point to where it would only last for about 5 minutes at most before it crashed. That only was that way for the first week or so, but it works perfectly now.

Only works for mobo's with holes

Tech Level: somewhat high - Ownership: 1 day to 1 week
This user purchased this item from Newegg
Pros: Looks nice. Probably works well if you have the right motherboard
Cons: Included kit only works on motherboards with holes around the North Bridge. Attachment with the included parts doesn't work if you're replacing a cooling device that has prongs that fit into loops in the motherboard.
Specifically, did not work for an ABit IC7-Max3.
Other Thoughts: If parts exist to make this work for such a motherboard, it would be nice if the instructions mentioned them.
