(just a quick basic fitting recap)

First off, any waterblock must fit over the CPU, and must cover the core. Then, to make sure it doesn't crush the core, it must extend to the 4 pads on the CPU, so that it stays flat, because if it tips, it will crush/damage the core.

Then, to hold it down, we have a number of options:
1-extend the baseplate with notches, and clamp it to the CPU socket tabs.
2-extend the baseplate with tabs (with holes) so that the plate can be screwed into the mobo. Alternatively, extend the cover plate.
3-use a hold down that is bolted to the mobo, then applies pressure to the block from the top
4-Thermal epoxy the whole kit-n-kaboodle. (not recommended!!!)

OK. back to the cooling part...
