A friend of mine recently brought parts to build a new computer except a hard drive. The question we have when we assemble this computer is that will we need thermal paste. Like I said in the topic that it is a 530J 3.0Ghz processor(Retail Edition). I know the Prescotts run hotter than most processors(I have a 520 2.8GHz myself). Ive been searching around about this question, and found that the retail edition heatsink uses some plate or something that cares of the thermal paste issue. I also heard that since they use this heatsink, that putting thermal paste voids the warrenty. But I also read that thermal paste is very much needed, and that if you dont put any on you will overheat and fry the processor. So does anyone know the answer to this question. Preferbly a person who put in a 5xx series processor, and has first hand experience to this question.
