Hi, im a noob at this stuff. I just bought a Volcano 7+ and Arctic Silver 3 for my computer. I am runnin on a Intel P4 1.6 cpu and wondering how do i apply the artic silver. Do i spread it around or what? thanks. also, how do i take off the retail heatsink and fan, and would i have to scrape or do anything with the thermal paste already on the chip. thanks
