CPU throttle, 1 core temp much higher than the others

[ThatGuyMoon]

Hello so i just randomly checked my cpu temps and 3 of the cores are fine at 60c on load but then core number 2 is at 100c and i have no idea why.
Here is a picture on core temp while runing the stability test on aida 64 its a i7 7700k btw

Strange?? Maybe a sensor is off, because I am quite sure Intel chips, especially 7700k, shut off if they reach 100C as a safety mechanism. Are you using a stress program during this like prime? Check if your OC is stable

Hey sorry i down voted ur answer i thought i could change my vote but i cant. Yes i was running the Aida64 stability test when i took that picture and yes my OC has been stable for aboub a year. its completely random and i have no idea why its happening.Is it possible that a stable OC just dies after a while? also why just 1 core, wouldn't they all be heating up?

Edit* I tried it with the OC off and still the same results

This is likely a wonky sensor. How does this core report when at idle and under normal load, like when gaming?

Also, have you scanned for malware/viruses lately, just in case?

I haven't tried running a scan its been a week since i last did a scan. Il start a scan and post an update when its complete

I would suggest only measuring temps with one application at a time. Apps can conflict with each other and report erroneous results.

The results are the same whether i use 1 or 2 programs i just used 2 programs in the screenshot in case one showed something different.
The scan is gonna take a while.. What else could be the problem? Yesterday i tried replacing the thermal compound but it didn't change anything

Scan came back as clean.

Sounds like a bad sensor reading (or sensor). What is the make/model of your motherboard?
