I pulled it off before reading this, but I'm having trouble understanding what you mean. I need to pry one of the ends off with a flat-head?
Also, I am wondering about CPU heat. The reason I wanted to take it off was that no heat is blowing out of the end where the Zalman blows. When I take the cover off after restarting the computer, the heatsink isn't hot at all. For some reason nothing has temperature sensors so I have no way of monitoring my heat (other than the GPU). I had a few freeze-ups and was wondering if the CPU was getting too hot.
