What happens if you leave the side off the case?
Temps still high?
That cooler does look under powered for the 7700K.
I am on air with my 7700K at 4.8 GHz and idle is like 29-31C and full load is like 70ish, gaming in the low 60's.
Yup, temps are still high I tried this one as well..
Here are some screenshots:

Your voltage is good so that's not the problem.
Your case temps are high though, 45C is high.
Sounds like you need to replace that AIO with a better unit or go with a high quality air cooler.
