I am getting ready to upgrade the processor in my 6.1 from 4 to 8 cores. I have looked and a few videos on the process and don't think i willl have any problems. But I am a bit confused about applying the thermal paste application. I will be using arctic silver and the website says apply a single line to the E5 processor. The CdW video says to spread a line layer over the entire processor. If you have done this upgrade what method did you use?
