You can't take the heatspreaders off without risking damage to the memory module. It will void the warranty as well as being very hard to do without damaging the chip.
Taking the heat spreaders off was easy. I took a heat gun, warmed them up, and they pulled off with the greatest ease. The only "difficult" part was getting off that goop that they used to stick the heat syncs on.
Now I have fully functional, but ugly, RAM that doesn't get in the way of anything
