You did use it, right? I've been told the Silver thermal compound works better and is worth the extra bucks.
Also, on the super duper heat sink/fan. Be sure it is flush with the CPU surface and not touching part of the ZIF (Zero Insertion Force) CPU socket. I managed to fry an Athlon because the edge of heat sink was resting on the "hinge" edge of the ZIF socket which was just slightly higher than the top of the CPU. Turning the heat sink/fan around 180 degrees did the trick (with the new Athlon :( ). There had not been a warning with the heat sink/fan manufacturer or with the Asus mobo manual about the potential problem. Expensive lesson.
