I thought I would dive in into it a bit and it turned out that's actually quite interesting...
Some sources claim the TJMax to be as high as 115C which would actually render all of your tested apps wrong.
It's unusual that HWMonitor and HWinfo64 report it differently too.
However since intel actually states max die temp 100C if you must choose then you should go with HWMonitor readings (Hottest core 67C; lowest dist to TjMax 33C; 67+33=100 )
All that being said technically all you should care about is your distance to TjMax and this reading will be the same in all monitoring apps.
