Hey guys, I'm about to design a custom heatsink for my system. I've got a little question and I'd like to hear your thoughts about this. As you probably know, the screws which are fixing the heatsink on the GPU are hold by two pieces of spring steel which get slightly bent when the heatsink gets screwed on the GPU. Now one possibility is, I could try to design the heatsink in a way that allows me to reuse those two pieces for holding the screws and fix them to the heatsink. The other option would be to just make a copper plate with holes for the heatsink screws. Do you think this would work as well? I imagine it'd require some care when mounting the heatsink on the GPU in order to prevent to much force getting applied on the die. I somehow think it may be difficult to get the heatsink flat on the die with such a design. What do you think? Are these spring steel screw holders necessary or not? Here's a pic in case you're not 100% sure what I'm talking about, it's the stripped down heatsink (no heatpipes, no copper plate, only the two pieces which are holding the screws are attached).
