What's the best air cooler for a smaller case? Im talking smaller than mid-tower. I have a buddy that wants a well built, overclockable system but he doesn't have the room for any of the giant cases most people use these days. He has purchased a very well ventilated small case, but we lack the room for one of those giant tower CPU coolers like the Zigmateck and the T.R.U.E. What is the best small cooler? I know it wont be as good as the giants, but that's not really the issue. We are just looking for the best of the best, of the small.
