I'm about to replace my IC7-G's NB HS with the Zalman NB32J, so I removed the heatsink and promptly put it back on so that I could come here and ask about it. The 'chip' of the north bridge appears to be much smaller than I thought, with many smaller tiny bits sticking up around. The stock cooler has some kind of tiny shim on it; do I need to transfer this to the NB32J? Should I be worried about either frying the small bits due to contact with the heatsink or squishing them while I apply the new heatsink?
