So I'm swaping out my old nvidia failed board on my latitude D630 for a used intel board.  I've cleaned off the old heatsink and CPU of the thermal paste and will use arctic silver.  The heatsink arm to the NB seems to be a pad rather than paste.  Can I just reuse the pad?  Should I use thermal paste on the pad connection to the NB?  Finding replacement pads of the correct thickness is a problem and removing the pad and just using paste does not look viable as there appears to be a significant gap between the heatsink and chip to bridge.  Anyone have a solution?  Thanks
