That was the thermal paste, you're gonna need to buy some thermal paste for when you put the heatsink + cpu back on the motherboard when you get it.

Edit: Also when you put the thermal paste on the CPU, only put a little splodge in the middle then put the heatsink back on and it will spread out on its own, but don't put too much on otherwise the thermal paste will squirt out the sides of the CPU.
