This might seem like a silly question to most of you, but this is my first time putting together a system an d I just don't know. Anyways, my question is: Is the black material that comes adhered on the bottom of the heatsink supplied with a P4 enough for a non-overclocked system, or should I also apply the paste that came supplied with my Soyo MB? If it makes a difference, it's a 2A GHz P4. Thanks
