I recently installed a Zalman 9700 LED using the S clip. After i tightened both screws, I can twist the cooler and I can tilt it slightly left and right, so when my case is closed, it's tilted a bit. I have no problem it being able to twist, but when it tilts, the cooler is elevated from the CPU slightly. I've searched a similar thread, and the thread starter mentioned only twisting, so I was wondering is it alright if it tilts a bit?
