I am not an expert but from what I have understood in trying to fix my own overheating CPUs, comparing your test with Kens which I believe was Intel stock cooler, it looks 14°C too hot Vitoi.
I can see your reported core voltage is 1.115v where set voltage is 1.108v so higher by 0.007v. Makes me wonder why the board is overvolting. You said 2012 BIOS so how old is this mobo? What model and does it have a BIOS with I7 4790K support? If not maybe try contacting the manufacturer about that? I dont know if it would be an issue or not but several Z97 mobos I was tracking got BIOS updates to run the Devil's Canyon cpus so maybe.
Also as I understand it, for this test RAM should be run at SPD rather than XMP for a like for like comparison. That can make a difference, though I found my first CPU which was RMA'd was more prone to heating with XMP than my second replacement CPU, though it does still make a couple of degrees difference.
You could also try reseating the cooler to improve contact and if available use optimised thermal compounds to be sure.
Once you rule out the seating XMP and BIOS support, if temps remain high like that, I would suggest discussing what it takes to get an RMA with your retailer then apply whatever tests they use yourself, to check it will meet their requirements for replacement when they test it.
Is all I can think of for now, hope that helps.
