Need help with 3900X & AIO

[FunksterPanda]

I just built the machine from my sig and the temps seem a bit high.
CPU is stock with PBO etc all on auto.

In a closed case 1 front 140mm brings cool air in, one back 140mm takes hot out, the AIO is on the top 2x120mm taking hot air out, room temp 24C and using Thermal Grizzly Kryonaut.

Cinebench R20 all core temps hit 80C.
Prime95 temps only hit 70C weirdly enough.
Battlefield 5 1080p ultra never goes above 65C.

I am coming from 1700 with an AIO and these 3900X temps seem high for the Arctic Freezer II 240 which in all reviews performs like a champ.

Do these temps look normal or should I be worried about maybe installing the cooler wrong or something else?

Any input is much appreciated.
Many thanks!

Did play around with it some more and here are the results:

I turned on PBO instead of auto and turned on AutoOC and set it to 200mhz.
To my surprise, it really did bump up the speed by ~200mhz.

So I ran prime95 and it set all cores at 4.0 (prior to PBO and AutoOC they stayed at 3.8).
The CPU used 190W (I checked the wall with a meter not only hwinfo) and the CPU didn't go over 85C.

I think 85C max temp at 190W in prime95 is ok but let me know what you think.

BTW I use Ryzen High-performance power plan.

Thanks!

I'm assuming you have the cover off the top of the case?

Yes I have left it open
