A well-aimed blast of compressed air will always provide some cooling, due to decompression cooling. Not as good as water, but some help.
Another advantage of air is it's ability to clear chips out of the cut. This helps give you a better finish. I use it on my X2 CNC mill.
For most of my milling cuts, I don't use any coolant. I'm more likely to use cutting oil or Crisco as a lubricant, especially with aluminum.
