Stumped on high Temps under load and low idles

So I have an 8700k that I actually feel pretty lucky with. I've got it stable at 5.1 ghz on 1.27v but I'm having a weird issue with my 100i pro AIO. At idle in windows I'm seeing around 28-30c but when I run the small load in OCCT, temps immediately shoot up to 90C. If I run medium or large in OCCT I never see it jump above 70c which I'm still not sure if that's normal. I can see pump and fan speeds in icue and I have them set to extreme. The fact that I can see it keep the temps low at idle and under smaller loads makes me think the pump is functional but most everywhere else I read people putting 1.35+ volts on this processor and keeping it under 75c at full load. Does anyone have any suggestions? I should mention I've reseated it twice and even threw cryonaut on it and saw temps drop a couple of C at idle so I know it was done properly. X pattern and all of that.

Is the chip delidded? If it is not then the temps are normal.

Yes, that's normal for a non delidded 8700k. Mine runs 18°C lower after the delid.

It's not delidded. Kinda nervous to do it tbh and figured something like this AIO would make the difference negligible. It's really that much of a difference?

Yea you need to delid it if you want reasonable temps.
You could throw 4 480mm radiators on it and it won’t help the temps as the stock TIM is so poor that the heat transfer into the waterblock is pretty much non existent.

Yes, even for aircooler it's a pretty big difference. I think everyone saw at least a 10°C improvement, but most people saw a 15°C improvement on average.

Get a Rockitcool kit. If you damage your CPU while using their kit, they will replace it. Super easy to do.
