Unless you are "driving" the latest model of motherboard, your tiny chipset cooler won't protect the underneath chip for too much time, should its fan suddenly stop. Prolonged use and dust are likely to prevent the impeller blades from spinning, and since the heatsink alone cannot dissipate all the chipset heat, it is likely to get fried before its time.

Zalman introduced a fan-style chipset heatsink that will be able to dissipate the chipset heat even without the need of using a fan. Its special, fan-like design maximizes the heatsink's contact surface with the surrounding air and thus, dissipates the core heat faster and more efficient than the classic, monolith-style designs.

The Zalman ZM-NBF47 is completely built of aluminum and reminds of Zalman's first CPU heatsink design. The cooler is 37x80 millimeters large and is compatible with all the chipset mounting options, be it mounting hole or loop-style attachment. The cooler's base is 30x23 millimeters and is made of solid aluminum, too. It has an excellent, mirror-like finish that dramatically improves heat conductivity.

The chipset cooler can accommodate different motherboards and mounting points, thanks to its steel brackets that swivel around in any direction. The ZM-NBF47 can be fully installed with the bare hands only, since it is extremely simple and user-friendly. This is extremely convenient, as tools that slip on the bracket's surface can easily penetrate the motherboard's PCB and send it directly to trash.

The ZM-NBF47 heatsink is comprised of 20 blade-like aluminum fins 0.5mm thick, that are disposed into a fan configuration, pinched together at the base. The air current can easily "wash out" the fins and transfer the excessive heat away. The case fan or even the CPU heatsink fan can substitute for a small, dedicated cooler.
