ZALMAN CNPS7700-CU 120mm 2 Ball Cooling Fan

Zalman bills itself as the "quiet cooling solution" and they have a reputation for easy to use, reliable products. They also have a reputation for creating products that look as good as they run. With the CNPS 7700 Cu, "bigger is better." A quiet, downward blowing 120mm ball bearing fan sits at the heart of a radial array of copper convection fins.

While it works silently in its normal setting, its Silent Mode virtually eliminates all noise as well as vibration as it cools not only the CPU, but the RAM, VGA card, Northbridge and other components. The included FAN MATE controller lets you choose in which mode the fan operates.

Heat is drawn away from the CPU by the pure copper base of the heatsink and it is transferred up into the twin semi-circular arrays of copper fins for dissipation. Both Intel Socket 775 and 478 Pentium 4 chips are supported by the 7700-Cu. It is also compatible with AMD 64 processors using 754, 939 and 940 sockets.
