I guess 120c is too hot for 7900x doing sustained rendering

It's the only way to be sure...

All 5 of the Intel chips I'd used with my old external water cooler shut off at precisely 106C. I know this because I've never seen 107 on screen
Generally if I'd seen 105 it was then too late to get to the cooler on/off switch in time. To my surprise none of the chips or motherboards failed over their years of heating abuse.

Although the OP states that its 1 core playing up, so perhaps the 120 is just for that one core? I'm just wondering what the overall cpu temp is as surely it cannot be possible to be 120c? Also would need know what cooling as said above. If it were a budget chip, I'd assume it was on the cheepo stock cooler with one of the legs not fastened.

The 10-core chip is estimated to be 322 sq mm big. It has 10 cores and each is tiny compared to the overall size of the die. https://www.anandtech.com/show/1155...-core-i9-7900x-i7-7820x-and-i7-7800x-tested/6
I can't exactly explain to myself how it would be possible that a cause for the higher particular core temperature could be something between the die itself, the chewing gum under the IHS, and the down surface of the cooler.

That poor CPU... running it at those temps is going to kill it very quickly.

Definitely something wrong with the CPU or cooler. A 7900x at stock will generate no where near those temperatures with a decent cooler.

Think when I had mine it ran at about 50c at stock on prime95 and that's with autovolts and turbo. It's the overclock that makes them hot.

Maybe that one particular core is already somehow damaged.

"Stock" settings of 7900X are rather fluid.
Only with motherboard/BIOS following TDP limit and throttling clocks its full load all cores power consumption is anywhere near advertised TDP.
Which shouldn't be no surprise considering what just four cores of same architecture take.

is it me or has he still not said what cooler?

It's not you unless I'm also blind

I've got one of these chips coming in a new rig this week. Due to this thread I changed to a 4.7Ghz pre-binned and delidded cpu. With a 360mm AIO and some good case air flow I'm hoping I don't have any of these issues.
