Downward pressure on heatsink?

Exactly as the subject says, How have you guys set up the heatsinks so that they are pressed against the ic's? I just need a few suggestions because i'm not sure how much presure they actually need.

You need firm pressure, but not REALLY hard, since you could crack the chip. Take the example from liquid cooling manufacturers for video cards. They use a thin metal strip that is pressed down on the waterblock to have it make contact with the die. You could also use heat paste, which will work well and won't require screws or pressure.

Heat paste is waht I would go with. But that's just me.

You may find it very tight and getting the pressure is easy to do but you can also make your own thermal epoxy. This link will show you how http://www.overclockers.com/tips683/
I tried this and it worked quite well for me. [/url]

the ram chips i believe have two convinient mounting brackets that are part of the board. you could make some clever device with those. too bad the other chips dont have them.
