In my antec 900 the fan is on the "bottom" blowing up toward the large 140mm fan. I believe that the top of your CM690 case is open...if so you'd want it to blow either out the back...or out the top...since heat naturally rises directly out the top of the case would probably be optimum..
One thing...on AMD systems the S1283 only bolts on one 1....meaning 1 direction. My Zalman could be mounted all directions in 90' intervals.
Like this. Also you always want the fan blowing across the fins.....not sucking thru the heatsink....as the fan blades actually compress the air slightly allowing it to absorb more of the heat transfer.
