Thermaltake E600MX build

[Lightning_Touge]

Hi all, Finally had time to swap cases. The O11 Dynamic mk1 I initially built the system on wasn't up to the task.
It's not as fancy as some of the awesome hard tubing builds I've seen here but I'm happy with it.
Specs:
Case: Thermaltake CTE E600MX
CPU: AMD 9800X3D + Eisblock aurora edge XPX
GPU: AMD XFX 7900XTX + Eisblock aurora + PTM7950
Mobo: Gigabyte X670E Aorus Master
Ram: 32GB G.Skill trident Z5 6000C30
Rads: 2x 360mm NexXxoS ST30
Pump: VPP Apex
Res: Eisbecher Aurora D5
Fittings: All Alphacool HF fittings except 2x bykski 45deg.
Fans: 11x Aigo AR12Pro.
Others: Alphacool 13/10 tubing, Alphacool TecProtec 2 fluid, Bykski flow meter, Alphacool fluid temp sensor, Bykski exhaust valve.

It is my first watercooled build (well second if you count the previous case). I'll give some details and would appreciate if some more seasoned builder give some advice.
Coolant temp with case open (520W CPU+GPU gaming load) is 32C, 35C with case closed (this is 12 and 15C over ambient respectively). CPU temp is a non issue at around 55C, GPU temp is also fine at 58C, 67C hotspot and 68C MEM. Case temp when closed is 26C (probe is front of the ram above the GPU power cables).
My question is, I have a feeling this coolant temp is a tad high and would benefit from a third radiator. Any insight on this?
Few friends have pointed out my fans being Aliexpress and I'm sure this comment will come so I'll address it straight away. These fans will surprise you, their performance matches the advertised specs when compared to more established brands. QC isn't great so I ordered more than what I needed and chose the best ones.

Thanks!

PS: I must say, I've dreamt of building something like this for the last 15 years but the feeling of "a small mistake could cost 1k in damage" isn't great ahahah.

Are you sure theres no air inside the rads? Tops are both above Pump.
Try turn backside fans also push in. Positive pressure will find a way to get outa case

Also try undervolt OC CPU/GPU. (allways, any system)

Thanks for the suggestion.
I can't say with 100% certainty that there's no air on the top of the rads but I'm almost sure. When bleeding the system I tilted the case in every direction a "thousand" times until nothing came out. Also there's never any sounds of "bubling" ever.

System does have an undervolt OC on both GPU and CPU.
-CPU is at -35 offset.
-GPU is also undervolted but I'm keeping the clocks high. It boosts to around 3000/3050MHz depending on the title and power is at around 450W TBP (total board power). I know this is not the efficiency sweetspot but I want to get everything I can out of it. .


As for the rear fans it doesnt matter much. I have a temp sensor behind the GPU, the air going into the back rad is about 3C/4C over ambient.
I honestly think I need another RAD for this system, but at 38C liquid temp I think I'm gonna be fine for a while. Maybe next time I replace the fluid and tubes I'll add it.
Also at that point I'll probably go hard tube since soft tube always gets a bit yellowy.

More RADs is all we need Im fine while Gaming and FPS Lock 100/120 with 2x 240x30 and 1x 280x45 HPE. (all intake) 14900K and 5080 Astral. CPU@ 5600/4300 P/E -0.055, GPU full throttle water is +6 to +8 over ambiant. CPU-Out thru 2x240 and GPU-Out thru 280.
Mabe change the PC position in your Room? Corners mostly bad ventet or just try turn your backrad to bottum intake? But 2 360x45 should work fine anyway
