I've bought a noctua nh-d14 and I want to use it with an i5-7600k the cooler came with a noctua nt-h1 cooling paste, I've checked the website where I've bought it and it didn't said anything about the paste being included so I've also bought an Arctic MX-4 (-,-). If I already have both I was wondering which is the better option, I've looked at some reviews online and they seem similar. I am confused because both of them calim to be better than the other one.
