Possible the CPU is damaged..TjMax is 105C for an i7-4820K whereupon PROCHOT will be asserted, as long as Thermal Management/Protection is enabled in the BIOS, and the frequency and voltage will be throttled down in an effort to keep the cores temperature in check so that no harm comes to them..If the cores temperature cannot be kept in check, THERMTRIP will be asserted and shut off the CPU, regardless of whether Thermal Management/Protection is enabled or disabled in the BIOS..Intel does not guarantee a CPU that hits THERMTRIP will go undamaged..THERMTRIP is usually about 10C to 15C higher than PROCHOT.
What's the cores temps getting up to with the Intel cooler now and what did they get up to when it 'overheated', if you know?
You can try assigning a fixed manual downclock of the CPU to run it at a lower frequency (maybe 2.9GHz Turbo instead of the stock 3.9GHz Turbo, or even 1.9GHz) and/or manually increasing the Vcore a little and see if it helps..If it works okay/better at a lower frequency and/or at a higher Vcore, that's a good sign it's damaged..Best way would be to try the CPU in another machine or try another CPU in yours and see how it rolls.
UD3 not UD4 boards support an i7-4820K (Socket 2011).
