I made a really dumb mistake last night while installing a wireless pci express x1 card. I normally grab the cpu fan to hold motherboard in place when snapping something in. Instead I accidentally grabbed the north bridge which I think is actually the north bridge heat sink correct? and it snapped part way off. I pressed it back in place and it seemed firmly in place. Started my computer, no problems and it's been running for over 3 hours. Should I take the north bridge heat sink complete off and reinstall? If so how do I go about that? Thermal paste? and if not what should I look out for in the future for north bridge problems. I've read in a post before that a north bridge fell off somebodies motherboard. That probably means mine is at huge risk of doing so considering it already sort of disconnected. A north bridge break down would be helpful thanks.
