It actually has a fan that spins faster, so it is louder overall (42dba vs 32dba rating by Zalman). Heatsink wise, same material as the 7700Cu but the colour is different. The fan is a red LED fan that spins 400rpm faster (+/- 10%) than the 7700Cu version. The Fatal1ty also does not include the FanMate 2 accessory.
You can do better for the price.
