One of the problems with old motherboard chipset heatsinks, apart from their small size, is the little fans almost always seize up. Constant use, time, and dust bunnies conspire to stop impeller blades from spinning. If the fan stops on a postage size heatsink, there's a good chance the chipset will overheat - there's just not enough surface area to adequately release the heat from the chipset into the surrounding air.

For this problem Zalman have introduced a small chipset heatsink called the ZM-NB47J.

The Zalman ZM-NB47J is a compact passively cooled aluminum chipset cooler that measures 37x37mm in size. This extruded aluminum heatsink is compatible with through-hole attachment methods. The base of the aluminum heatsink is a mere 24.5x37mm in area.

The ZM-NB47J heatsink comes with a mounting brackets that fit into channels in the side of the cooler. Each steel bracket swivels around in just about any direction so the little northbridge heatsink can accommodate different motherboards, and mounting points in any orientation.

The versatility of this system allows the Zalman ZM-NB47J to fit on a wide variety of motherboards with a minimum of fuss. After assembly, the ZM-NB47J is installed without the use of any tools.

Unlike our normal CPU heatsink reviews we won't be doing any temperature measurements. Here's a quick look at the Zalman ZM-NB47J from all sides.

The Zalman ZM-NB47J heatsink is made from an aluminum extrusion, cut into fins 2x1.5mm in size. For a passive heatsink such as this, it's understood that the user will have some airflow directed towards the heatsink - a case fan, the CPU heatsink fan exhaust, whatever.

There's not much else to the Zalman ZM-NB47J really, and in that respect it makes a useful replacement for expired northbridge chipset heatsinks. There is no fan to break with time, and its' surface area should ensure adequate cooling with a moderate breeze moving over the aluminum fins.

The only shortcoming we can see with the Zalman ZM-NBF47 is that it won't be of much use on modern Intel chipsets - the 975X, P35, X48 are all far too hot for a small aluminum heatsink such as this. It's hard to imagine a motherboard with a massive copper and heatpipe chipset cooling system being replaced by a cooler as compact as the Zalman ZM-NB47J, so don't try. As a general rule of thumb, we suggest you only replace failed motherboard chipset heatsinks of about the same size as the ZM-NB47J.
