I repasted my Dell Latitude D530 with good results, 20*C reduction in CPU temperature. However I didn't have any thermal tape available to do the northbridge correctly, instead I put a huge blob of thermal paste. A few weeks later, I am having some occasional instability with explorer and firefox, it could be caused by memory issues (northbridge). I am willing to tear it apart and do it with a copper shim to fill the gap but I am unsure as to the thickness. I am not sure how thick the thermal tape was, maybe 1mm? I don't want to crush the NB chip with a shim that is too thick. Does anyone have a thickness suggestion? Otherwise I'll just buy some thermal tape. Thank you. edit: I am looking at thermal pads, Are the generic blue colored pads on ebay legit? Or should I be buying the 3m brand 8810/8815 stuff that is a lot more money. Has anyone ever tried Thermagon 6100?
