I think the only true accurate test would be physically testing the temperature of the core. Everyone has an opinion about which one gives the 'correct' reading, most people believe it's core temp and so i'd just go with that .
according by intel temperature 72.6 C if over than it , i think not safe for longtime
Some other things to check, take the sides off of the case and get some air flow with a room fan to see if that helps. Make sure that the CPU is clear of major components like video cards and hard drives. Bundle up any loose wires inside of case that may restrict air flow.
I would reset the heatsink before you run it again tomorrow. Even if the paste isn't settled yet, it should not be hitting anywhere near 100 C
Thanks, that seemed to do it, now running OCCT my max temp is 70c, a little high for my taste/ or what i expected, but much better than 90C. When i lifted the Heatsink i noticed that only about half of the thermal paste made good pressure contact, the other half of the cpu had a very light film on in, which indicated i didnt push the pins in far enough. Now the only question i have is about turbo boost, im only getting 3.5ghz according to the intel turbo monitor. i was hoping higher around at least 3.8, but maybe because the max temp is 70c it wont go that far?
