Not sure if this is the right forum to ask this, is there another forum or area that's better suited?

I built my first pc in 15 years in April and was a bit of a learning curve, lost some hair in the process. There were some issues that I didn't resolve at the time as it seemed stable enough, I was able to complete the tasks I needed at the time and had enough of scrawling the internet for fixes. One of the main issues was the CPU overheating and constantly being 100 degrees (80ish when idle), but I read in a few places that the 13900k runs very hot and was not something to worry about so I moved on.

However I've had to do some rendering and getting the blue screen of death and the programme I've been using(sketchup/vray) has been frequently crashing. My first thought was to see if I can do something about the overheating cpu. I'm using a peerless assassin, I was thinking about upgrading to something more high end but from what I've read in various places it doesn't seem to be the issue here and it's not going to half my temps.

The crazy thing is everywhere is showing that my CPU is 12700k when it's a 13900k. In BIOS, CPUID, coretemp, task manager, device manager... everything reports it as the wrong processor. I just tried flashing the latest bios to no avail. Not really sure what other options I have, I've scoured the internet but there is very little out there. The box I have is for a 13900k, I'm more than certain when I looked at the back that's what was on the back. I dont have any paste to take it off and check atm but ordered some prime delivery. But I'm 95% sure it's the correct processor.

The 13700K string is hardcoded onto Processor registers. If it says 13700K, it IS a 13700K. To add insult to injury, check how many cores you have. 8P + 8E = 13700K.

You were scammed. And if you purchased in April and took this long to notice... good luck getting your money back.

Not to mention delidding, and the person buying both cpu and then putting 13900k lid on the 13700k proc and returning it for whatever reason, alot of shady ppl out there.
