The Ideal heatsink hold is provided by a single articulated pressure point right in the vertical axis of the center of the core. The pressure point is connected to the holds at socket lugs or mainboard holes by some kind of rigid or flexible element (arm).
This way any unbalance of claming force between the holds is automaticaly compensated by the pivoting arm.
Most of the socket clips comply with this concept, but almost none of the mobo hold down. The best one I’ve seen is from Paul Vodrazka. There the four springs press down the connecting “spider”. So when you tighten the center bolt, in compress the springs and apply all the force only at his tip.
