@Fullmental Thank you for being willing to type it all over again! It had me barking up the wrong tree as I interpreted PROCHOT(processor hot?) as some kind of core, or system agent thermal problem. I added another fan and adjusted the fan curves, no change. I tried to roll back to a previous bios and the Asus flash utility would not take anything but the current bios so I flashed that for the heck of it. I went ahead and scrapped my previous OC settings as I read that the new bios requires a fair amount less voltage for some people. It looks like this bios isnt the bad one but the previous one I was used to and stable on was buggy at the very least. I can now boot at 5ghz with less than 1.3v, I could never even post at 1.3v previously. Now it looks like stability will be near 1.35v instead of 1.4v. Here is a photo of my current set up with the additional fan up top and the rear set up as an intake now.

@Crunchy Dragon, Awesome! Thanks. I didn't know if I needed to move it to the right place as I posted in general discussion earlier.

I am at a loss and admittedly new to the scene. I have overclocked my delided 8700k to 5.05ghz at 1.405 volts (didn't win the lottery) on my Asus z370 F gaming Mobo. It's cooled by a Corsair 115i pro aio. My problem is that in prime 95 (avx and non avx versions) I now get the IA:prochot limit and the CPU down clocks to 800mhz as if it's thermal throttling, yet it never reaches 82c (it also doesn't seem to pick a certain temp when it trips). Is there a thermal sensor for vccsa or vccio that I can't see causing this? I did just update my BIOS and this makes me suspect it's a problem with version 1002. It didn't do this before as far as I know even after hours of testing but I could be fooling myself or perhaps a setting got changed (even though I've combed through them for days). Thanks so much to anyone who can throw a little knowledge my way! I hope the photo is readable. Also in my fit of panic I posted this wayyy in the wrong place. Should be under Hardware.
