hmmmm, with the upper outtake fan, i would suggest turning it 180 degrees, so that the air flows upward, through the zalman to the outtake fan in the top of the case.
or turn it where it is blowing out the rear. either way would be better than having it blowing downward as it is now.
i'd use that outtake fan to it's full potential, hence the reason i would turn the zalman 180 degrees.
