i owned both the max3 and regular ic7
i ran the thermalright sp-94 heatsink on them both, but i had to file about 1/4th inch off the corner of 3 fins of the max3 northbridge heatsink to get it to fit, wasn't much of an issue
the northbridge heatsink is pretty large on the max3
the shorter (but identical looking) nb heatsink on the non-max3 makes no issues
most all the incompatibilites in that list are related to the the NB heatsink i believe
I can take a picture if you want
