PC Stats posted a review on the Zalman Fatal1ty FS-C77 Heatsink

The Zalman Fatal1ty FS-C77 heatsink is the Zalman CNPS7700-Cu heatsink with a coat of red lacquer applied and a slightly beefier 120mm red LED illuminated fan. The two heatsinks are compatible with the same variety of processors, but the CNPS7700-Cu is skewed for silent running while the FS-C77 ships without the Fanmate 2 fan speed controller. Apart from these three differences, the two heatsinks are identical in every other way. The Zalman Fatal1ty FS-C77 is a large cooler by any measure, and unlike every other Zalman heatsink this one is entirely tuned for performance. It's translucent 120mm fan rotates at 2400RPM, and a series of red LEDs light up the blades nicely in a darkened case.
