This is my first time building a system and I just got a Phenom ii x3 720 BE from newegg. I plan to use the stock heat sink for a while at least and I am surprised to find out that there is no thermal compound come together with the CPU. Instead, there is something like a paste (with rough surface) attached to the bottom of the heatsink. And the instruction does not mention anything about applying the thermal compound neither. Should I just attach the 'paste' to the CPU or should I tear if off and apply some thermal compound like OCZ freezer? Thanks.
