well ya there's danger with any mod to do with overclocking... I've never done a pencil mod but I did do that safer route and found out what I needed to change the resistance to and then just replace or double mount the smr's
but I feel this is easily undone with erasers... lol all it is, the conductive lead... just make sure you got good enof cooling (witch is a given)
