you shouldnt tighten them all the way. it pushes the base of the sink to the motherboard, in such a way that it might actually break.
how i did it: overtighten them slightly, so you can see the mobo bend a little under the pressure, then loosen each bolt little by little untill the mobo is perfectly flat again. that way enough, yet not too much pressure is applied.
