Does anyone know of some sort of thermally conductive paste, filler, gel something that will fill a gap in between two metal pieces. I want to dissipate heat from one object through to an aluminum housing/heatsink. Based on the design its not possible to have a full contact and there will be gaps. Anyone know of any products to maximize the conductive heat transfer?
