Question Case airflow - High CPU temps *apparent* low AIO airflow?

Hey all. I recently upgraded my system to a 5900X and have been running some benchmarks. I have been running at about 84 degrees C during these tests and I am a little worried. I havent seen this high of temps regularly and my 3700x seemed like it was doing just fine. I've attached a quick diagram on how my fans are currently set up, and I am wondering if I did it correctly as I feel almost no airflow from the side the air should be exiting the radiator from. The rear exhaust fan is pulling alot of air out of the case but I am still concerned. Should I be changing anything?

Specs:
Ryzen 5900x (PBO + XMP)
Gigabyte Aorus Elite X570
32gb Gskill trident Z neo

3 Lian Li stock case fans (front intakes)
3 Coolermaster LL120 (rear, top, bottom exhaust)
GPU marked in green

some things you should try;
move the top-front exhaust fan to top-rear position,
remove HDs from case(along with drive trays) to an external dock,
move PSU tray "exhaust" fan to the very bottom-front where it can be used as an additional intake,
and make sure fan curve profiles are aggressive enough.

also if CPU temperatures are higher than anticipated;
look into setting up the radiator in a push/pull configuration.
I feel almost no airflow from the side the air should be exiting the radiator from.
if the radiator is placed in front with fans pulling air into and through it you would not feel any "side" air exiting.
the radiators heat will be pushed throughout the case and the top & rear exhaust will be the only place you would feel this.

The computer is definatly running hotter than id like. Its idling between 45-55 deg C. Sometimes hits 60.
remove HDs from case(along with drive trays) to an external dock,
Ive removed the entire drive enclosure previously to fit the radiator.

move PSU tray "exhaust" fan to the very bottom-front where it can be used as an additional intake,
So try flipping the fan 180 and moving it forward?
and make sure fan curve profiles are aggressive enough.
I've got a pretty aggressive curve, they're quite loud when idle.


move the top-front exhaust fan to top-rear position,
Unfortunately there is no room because of the rear exhaust fan.

no.
moving it forward would still be on PSU shroud.
you want it on the lowest level pulling in cool outside air directly.
it would be where the drive tray was originally.

your edited image shows tray and drives still located here,
may want to re-edit to show your real world usage/setup.
Unfortunately there is no room because of the rear exhaust fan
are there only predefined 120mm slots?
should be able to place this fan anywhere along a long track in the ceiling.


if this case is new, you may want to just return it and get something with much better options.
