i just finished pulling the heatsink on one card and taking pictures of the poor thermal paste job. not going to bother posting them now. wow, some of those are a joke! mine had a couple of chips without paste. some of yours have a couple with paste.....
can you post what you feel is the ideal amount of paste?
i used one 4ml tube of paste for one board. little dab on each chip. hope it's enough.
will reinstall tomorrow.
