This is my first build and I'm wondering whether it is safe to use the thermal paste that came attached to the cooling fan. How long will it last for and is it sufficient? Do I have to buy different paste and apply it directly to the cpu? Can I mix new paste with the pre-set one? Do I remove the pre-set paste all together? I only intend to use my pc for gaming and other less demanding uses.
When you apply thermal paste you first clean off the old paste off the CPU and HS with cleaning alcohol, get the new paste and put a small blob in the middle (if more liquidy then apply less) and put the cooler on.
