Dude, you really need thermal paste/grease. If it is a boxed CPU, one that comes with cooler, there might already be a pre-applied pad on the bottom of the cooler.
Not the best quality, but it will do for standard application.
No surface is perfectly smooth, and air is an insulator. The grease serves to fill the (microscopic) gaps between the CPU and heatsink.
