Question CPU Temps in NZXT H510i

[rqres]

Hi,

Like a month ago i finished building my first gaming PC:

i7 12700k on Gigabyte Z690 AERO G
32GB of 4800MHz Kingston Fury RAM
Gigabyte Vision RTX 3080 10G LHR
Lian Li Galahad 240 CPU Cooler
Corsair RM850 2021 Edition PSU
Built in the NZXT H510i Case

I've got the 2 included case fans in the back and top getting air out of the case and the AIO in the front pushing air in the case through the radiator
Idle temps are 24-30C for CPU and 47-50C for the GPU

Yestarday I decided to stress test my PC
I ran Cinebench R23 and FurMark at the same time for 30 minutes

These are my recorded temps of the last 2 minutes of testing:

I am quite concerned about my CPU temps in this Case. As you can see the hottest cores managed to hit 100C in 30 mins of stress testing while running at a 22-23C ambient temperature. My room gets quite hot on summer time, in the 27-28C range, so I'm worried I might have some issues.

Having the exhaust fans set to Performance in NZXT CAM, which gets them up to 100% at 65C CPU temp, the pump at 100% all the time, the AIO Fans on silent mode which gets them to 100% at like 70C CPU temp, and the GPU Fans on Auto, so they were averaging around 87-88%.

What should I do to improve my temps? I thought about a push and pull configuration on my radiator, but I'm not quite sure on that because I only got about 3cm of space between my GPU and radiator. I'm afraid of having to either swap out the Case for one with better airflow, or having to mod it to add a mesh in the front.

Hope someone can help me out, Thanks!

A case with a mesh front would do wonders for radiator temps, if nothing else.

how much ventilation has it got on front of case? where are those rad fans getting air from?

the cores didn't change speeds, so it wasn't slowing it down if we ignore the drop right at start when it went from 62c to 98c

What fan plans do you have on AIO? is there a medium setting? My AIO has quiet, balanced and extreme plans, I generally run in quiet, although its max isn't 65c

you could add more exhausts and make it reverse pressure, that will suck all the heat out of PC. Since you have AIO it doesn't matter how many exhaust fans you have.

Worth remounting and repasting the cooler block as well, make sure its all tightened down properly.
