hello everyone I am doing my very first build here and got a question. first my setupo so far(still building) Asrock H61M-GGS 1155 socket H2 board Intel core i7 3770k 3.5 ghz 16 gb dual channel DDR3 memory seagate Barracuda 1 TB HDD Need advice on a basic video card as well. My question about the paste is that I boughjt a i7 processor from ebay(used) it comes with the stock heatsink and fan. How do I know if I need to apply new thermal paste? This is my very first build and just dumped $285 on that cpu so just want to know how to keep it cool! Also I purchased an extra 120mm fan to go up front does it need to blow out of the case or act as an intake?? Thanks for any replies!!
