ZALMAN CNPS7700-ALCU 120mm 2 Ball CPU 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 AlCu, "bigger is better." A quiet, downward blowing 120mm ball bearing fan sits at the heart of a radial array of aluminum and copper convection fins.

While the fan runs at a low 32 dBA in its normal 2000 RPM setting, its Silent Mode drops it nearly 50% to 20 dBA as well as eliminating vibration. With its unrestricted flow, 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 aluminum and copper fins for dissipation. The 7700 AlCu is only 2/3's the weight of the pure copper model. Both Intel Socket 775 and 478 Pentium 4 chips are supported by the 7700 AlCu. It is also compatible with AMD 64 processors using 754, 939 and 940 sockets.
