Sounds like you need some Arctic Alumina (http://www.arcticsilver.com/arctic_alumina_thermal_adhesive.htm), as long as you never want to take it off that is :))
My laptop SSD heatspreader doesn't seat flat on the controller chip, so it's NOT TOUCHING all the way.. It's stupid, cuz the only 2 screws are on diagonal corners of the heat spreaders, which leads to this outcome.
