cpu CPU overheating problems

[Enroit]

I have an Intel i7-8700k. It's worked great for me for the last couple months. A few days ago I decided to get a new SSD and psu. After installing these new components I was very happy with performance. The SSD I had bought had come with an optane as well so I went into bios to allow activation of this optane. After I had done this my fans on my radiator and case started going crazy and I checked my CPU temp, and it was at ~65°c. I undid what I had done in bios and hoped that would fix my problem. It did not. Being sort of knowledgeable on computers I took off my old thermal paste, applied new stuff, and reseated my liquid cooler. This seemed to have worked as my temps dropped to 35°c, what it used to be. Making sure that it wasn't a fluke I restarted my computer and agian the temps at idle reached 65°c. For the last 5 days I have been scowerring my own knowledge and this forum for any solution. Nothing has worked and I'm about to see if I can replace my CPU as I believe that may be my problem.

What do other programs outside the BIOS, such as MSI Afterburner, NZXT Cam, etc say in regards to your CPU temperatures?

What motherboard and cooler are you using?

Thanks for the replies, so quickly aswell, but I believe I have found the problem. My h100i v2 liquid cooler has failed and needs to be replaced. I believe and hope this is the problem.
