i9 13900k showing wrong CPU (as i7 13700k)

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.

Hi sorry I'm a bit unfamiliar with some of the terminology. I just realised it's showing as i7 13700 not 12700, but should be i9 13900k.

Here's a couple of screenshots of what I'm seeing










When it crashes either SketchUp just disappears instantly, or I get the blue screen of death and need to restart.

I'm not sure how to check the bsod report, going to look into that now thanks

was the cpu bought second hand or from online retailers?, it sounds to me the cpu may have been delided on purpose and a 13900k ihs has been glued back on, if taskmanager, device manager, cpuid and coretemp are all showing a 12700k, then thats the cpu you have, if you can i would strongly recommend taking the cpu out and giving it a very good looking over, check the cpu carefully and if you can post pictures of the ihs and where it is glued to the chip, also post a picture of the back of the cpu the 13900k will have a fair few more transistors compared to a 12700k, i'll update this to show both cpu's (13900k) vs (12700k)

Sorry I wrote the 12700 but its actually showing as i7 13700k, but it should be i9 13900k

I took the cooler off and it is def a 13900k

Hey guys thanks so much for the replies. As it was suggested the lids were in fact switched, on closer inspection this morning you can see at the bottom (ignore the arm hair, yes it's an air hair) there's a slight gap at some parts where the lid meets the board. I spoke with amazon who instantly offered a refund which I was surprised about. But I was armed with the information between here and toms hardware, and pre-empted that they would find my chip was probably a return though sold as new. The ridiculous thing is I had searched on my laptop (when autofill was suggesting terms last night after taking the chip out) about it being the wrong chip at the time but came across a post where someone suggested the mobo can detect the wrong chip if the BIOS predates the release of the chip you're trying to use. Along with everywhere saying the 13900k runs really hot I just assumed it was fine.

Have a bit of anxiety about returning the chip though as I've read similar stories about people being offered a refund and then the item going missing. They won't collect it which is concerning, but have sent me a QR to drop off at the local post office.

So glad I wrote on the forums as I was planning on trying to reseat with paste I have coming today, failing that shelling out £200 for a new cooler that I can't really afford atm due to my car dying on me last week and needing replaced.

So thanks again, have a great weekend!
