Thanks mate !
bug why mate ? im pleased to help
i took the IHS off just using what i showed gently on the corners and then moving around, then popped off clean that black thing over the PCB of the chip clean all with isopropyl alcohol and replaced the paste over the die, then just put over the IHS you will see it goes loose, so you put it on the retention mechanism it will move just be sure to align it good and thats it, and i did it with my mobo on lol i mean inside the chassis
cheers hope it helps !!!
