Allrighty then the problem sort of solved itself.
After letting prime burn the CPU at a steady 70 degrees for a week the max temps at the same overclock settings are only 72 degrees in prime after 1 hour of extreme burning mode. During rendering it stays below 70, makes me happy.
The initial overheating problem is caused by the ram though. If I remove all my 24GB and leave 1 4gb stick in there the CPU temps drop 10 degrees!
It is running exceptionally hot at 24GB ram.
This concludes that there is nothing wrong with my H60, only that a CPU runs way hotter if you put more RAM in your machine.
One funny I can't withheld you:
Saw this after the overheat protection of Coretemp put the system to sleep. Not an accurate readout ofcourse but funny nonetheless
Those temps are Oughtfully Crazy.
