I've personally never done it exactly like that but I have cut the whole CPU part of the shield off in the past and mounted the heat pipe directly on the dye. You have to be careful though because doing the way I did there is a chance you can crack the dye or get uneven mount and personally I noticed no temperature difference so I would just do it with the copper sticker intact. That's just my input though.i saw some people remove the copper tape.
removing the copper good or bad idea??
