What is so special about pure nexus?

I tried pure nexus resurrection remix aicp and maybe briefly some other rom with the stock kernels and then with elementalx and elite kernel and i found out that all roms i tried except the pure nexus and both kernels (on pure nexus too) make my 6p heat up to insane temperatures almost instantly when running light things such as a web browser (no games or video) and by insane temperatures i mean the upper part of the glass gets nearly too hot to hold and the whole body gets less hot but still very hot. For some reason this does not happen on pure nexus with the stock kernel and it can stay between cool and slightly warm while doing the same things that make other setups nearly melt a hole in the phone. I know all about how the snap 810 runs hotter than other chips but this just cant be normal and on top of that it works flawlessly with the stock purenexus kernel. So, does anyone have any idea what might be causing this? I assume its going to be a rare or maybe even a one off issue, since i don't see much in the way of similar issues from other users but i really have no idea what could cause it. (BTW, each rom was flashed after wiping everything and each kernel with a wipe of both cache options in twrp so i doubt that any issues could be caused by that)

Seeing as the only bug is a locale after reboot change, can any of the most mighty devs here create an AOSP style ROM from it or use the base of that ROM to stabilize the current set of custom ROMs?

I am a novice be nice to me! :cowboy:
