Zalman Northbridge Cooler: Great Quiet......passive cooling!

1. ZM-NB32K does not require a fan, thus does not need to be powered, and does not generate noise
    or vibration.
2. The Northbridge chipset can be cooled to an optimal temperature without generation of noise.
3. You can adjust the direction while in installation. So you can prevent the interference with CPU
    Coolers and other components.

Recommended CPU Coolers:

PS6000 (Socket 462), CNPS6500B (Socket 478), CNPS7000B (Socket 462/478/754/939/940),  
    CNPS7700 (Socket 775/478/754/939/940) and CNPS9500 (Socket 775/478/754/939/940)
    allow more stable and silent operation.

Compatible with Northbridge chipsets that do not have a built-in graphics core. Must have holes around the chipset.
