My vid card,; Radeon, dosn't have holes, so I just got done Lapping the senfu water block I put on it, removed the thermal tape, cleaned up the gpu, put thermal Paste on the gpu, except for the very edge of the four corners. Put a Very small drop of super glue gel on each corner, applied the block, and started up the system, ran 3dmark 2001, and my temp taken with a probe on the back of the gpu never made it to 77f. It works great...... and the glue holds very well.
