I am finally getting my Sandy Bridge replacement motherboard and have a question about removing the processor. I have the i5-2500k and it is not overclocked, I was just using the stock heat sink. Since the processor has the thermal paste on it, I imagine that will need to be replaced when I remove the processor and heat sink and put it on the new motherboard. I am just wondering if I just need to buy some thermal paste, and if the paste that is on there now will have to be cleaned off or does it just kind of disappear since it has been on there. Or am I better off buying a different heat sink or cooler that is not too expensive. I don't really have any heat issues though since it is not overclocked. What do you guys think is the best bet?
