Thermal Paste

In my own genius, I bought some Arctic Silver 5 Thermal compound not thinking that the Hyper 212 Evo I ordered would come with any. However, since it does come with some cooler master branded compound, which should I use? Does it matter, or is there a actual performance benefit to using the Arctic compound?

Use the Arctic Silver, usually thermal paste that comes with CPU's and coolers are kinda meh.
