Hi I have a problem with my new cpu. Here is my setup:
i5 3570K
asrock Z77 pro4
corsair 650 tx v2
cpu cooler: spc spartan 923
AAB cooling thermal grease 2
2x4gb hynix ddr3 1333@1600
Previously i had i5 3350p clocked at 3.6 and it runned just fine with temps 67-72 under stress. Then i bought 3570K set it to 4ghz and stress tested it. The temperatures immediatelly went to 100 degrees. I checked with speedfan, open hardware monitor and gpu-z temp of hd4000. I made sure that the heatsink sits properly and is clean but nothing changed. Then i delided the cpu and changed that old hardened thermal paste on the die to a new one, But the temperatures were maybe 5 degrees lower at idle. At idle they go down to 29-30 at 22 room temperature so I think that it's not a problem with connection to the heatsink.
Other cause could be that the cooler is too small but few years ago I had an athlon ii x4 at 2.9@3.4 which has 95 W tdp and the temp never exceeded 80. And with Xeon 1240v2 (essentially i7 3770) they were under 83.
There is also preety big difference between the individual cores and it is fluctuating a lot, like 75 in one second and then 90 and back to 75 which didn't happen with previous cpu so i think there might be something wrong with temp sensor.
Heatpipes at the place closest to the cpu are around 45-50.

My conclusion: as the temp goes immediatelly from 30 to 100 under stress
1. connection to the cooler is not right, but I checked that a few times. Maybe thermal paste is bad?
2. sensors on cpu are faulty. Or maybe somehow it is drawing more power than needed?
What do you think is the issue?
Edit: After few hours of trying to fix it i looked at the cpu and heatsink closely and there were something like a burned points where are the corners of a cpu die. Now I think that the paste that I have is either old or fake.
