  • ZM-NB47J is compatible with all Northbridge chipsets that do not have a built-in graphics chipset Caution: ZM-NB47J can not be used on motherboard that lack mounting holes around the NorthBridge chips

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'!

  • newegg Supreme Cooling With maximized heat dissipation surface area, the ZALMAN ZM-NB47J heatsink delivers supreme cooling to your motherboard Northbridge chipset without generating noise.
  • newegg Easy Installation With bundled innovative push pins as well as bolts, nuts, links and springs, the installation of the ZALMAN ZM-NB47J heatsink is quick and easy. The direction can be adjusted to prevent the interference with CPU coolers and other components.

Pros: Kept my HD4870 1GB (XFX) cooler and quieter than the stock heatsink. The ability to manually control the fan speed was a nice option.

Cons: None.

Overall Review: With a well ventilated case (HAF 932 for me) this heatsink can really help bring the temps and noise down.

Subjectively, I think the copper looks good.

Pros: Looks nice, quality

Cons: Not as big as I thought. Maybe teh same amount of material as alot of other NB HS's, but for me, much more was involved in the cooling fins, and I believe that made the difference.

Push pins were tiny, my GA-MA770 ud3p has HUGE NB pins, I had to work out an 11th hour solution using four zip ties: push one zip tie through mobo hole, bracket, spring, then the other on top to hold down. Works fairly well!

More push pin options would have been nice!

Overall Review: I added a 40mm fan on top of this sucker. Used some simple deck screws to screw down through the fins of the HS. Got a cheap active on NB and I've managed to push my NB another 200hz higher because of it!

Nice 4/21/2011 3:25:09 PM

Pros: Fit onto my old MSI Neo4 Platinum SLI (MS-7125).
Removes the heat from the smoking hot nForce4 chipset
Price

Cons: Bottom surface is blue anodized; should be bare metal for least thermal resistance

Overall Review: Pin fins and mounting method design makes this heat sink forgiving to motherboards with poorly placed chipsets. Great purchase to replace those stupid 40mm fans on a lot of chipset heat sinks.

Efficient, inexpensive cooler 4/18/2011 8:19:05 PM

Pros: Lowered Northbridge temps on my Gigabyte G41-M Combo drastically. Nice fit, even with a Zalman CPU cooler right above it. Cool blue color, matches my blue LED scheme in my case.

Cons: Had to use original push pins from old Northbridge heat sink because supplied ones were too small in diameter to snap into my motherboard (Gigabyte G41-M Combo). Had to drill out holes in links to make the old push pins fit. getting links to line up properly before tightening links screws a somewhat tedious process.

Overall Review: If you're not at least somewhat handy with tools or don't have the patience to do this right, I recommend getting someone more tech savvy to do it or not doing it at all.

Works fine 4/14/2011 7:14:19 PM

Pros: Attached easy. No moving parts, so it made no sound (obviously). Seemed to work well. Nice color.

Cons: No problems.

Overall Review: Wish I bought it sooner and hadn't bought a fan first.

Cooled me down about 10c 2/4/2011 3:22:51 PM

Pros: Cooled me down about 10c on my MSI-770 g45

Cons: It doesn't feel tight on, it is on properly but just doesn't feel right...

Overall Review: This will fit most of your motherboards from AMD, just don't loose the screws and nuts, they are very small
