I have a 1.2gig @266 t-bird (retail) in the mail on its way to me. Should i get a better fan/heatsink than the one they are shipping me? I do plan on overclocking one day but not immediattely. is it okay to pull the fan/heat sink off the cpu and replace wtih one that is more suitable for overclocking? And would anyone trust the themal compound which is already applied to the heat sink in the retail package? should i just go buy some other themal compound myself and apply that. I am a first time cpu builder and not sure any help would be great.
