First Watercooled build, looking for temperature feedback

Recently finished my first water-cooling build, thought I'd share since it's definitely neater than my last PC!

- Fractal Define R6
- ASUS ROG STRIX X570-F
- AMD Ryzen 9 5900X
- Corsair Dominator Platinum 32GB 3200MHz
- Nvidia 3080Ti FE, EKWB Special edition vector block
- 8x Noctua NF-A14 140mm Industrial 2000RPM
- 420mm top and 280 front Rad
- All EKWB water cooling parts
- Corsair Black XT Acrylic tubes - Corsair 750RMi

Since this is my first Water cooled PC I've nothing too compare my temps to! I'm wary of people online bending the truth slightly on their reported temps, so some feedback would be appreciated.
So I was playing "A Plague tale" on 1440p, limited to 144 FPS, on ultra settings, no overclocks on either GPU or CPU, RAM running at 3200. water temp not shown but is stable on load at 31*C. Room ambient is around 18*C These where my temps:

Not sure if these are high but you can see once the game is shut down the temps quickly drop to idle, so I'm assuming this means a good transfer of heat in the blocks to the water. you can feel the pipe coming off GPU is hot compared to input pipe. Obviously great improvement over my air cooled one which would be 70/80*C on load.

On idle (once fully heat soaked) I get 26*C water temp, 31*C CPU, 34*C GPU, which is a massive improvement from my last air cooled build, where the 3080Ti was at 50*C on idle, which impacted on CPU temp of around 40.
My fan setup is so overkill I'm super happy with it, with 18*C ambient I can get water temps down to 22*C on full speed, but boy are they moving air and loud! although my PC is in a different room so noise isn't an issue.
 
Welcome to the forum!

I really, really like the dark theme of the build. The tubing, fittings and blocks look great. The whole thing comes together really nicely.

What is the GPU temp while still under full load after 1hr of gaming? I’m looking at the graph but I’m not sure that I’m reading it correctly.

Mike’s thread here might help since he managed to gather quite a few reports on watercooled 3080 temps you can compare to.

Here’s another that might help as a reference, but it is about the 3090 so keep that in mind.

Thanks man those other threads will be useful! just wanna make sure al is good since never water cooled before.

Those temps are after over an hour of gaming

And yeah I hate all that RGB light show nonsense! shame they don't do black coolant! only turned them on blue because they're the only parts that have them

Also why do you think the rear fan as intake would help? there are also 2 of the same intake fans in the bottom not visible
 
Your build looks great and your temps are excellent. Way better than I have with my loop but I barely turn my fans up at all.

If you have the rear fan as an exhaust then it will be pulling air away from the rad and less air will be passing over it. Have it blowing air in and it will promote positive air pressure and more air will flow through the top rad. Thats the theory, you can always test and see if theory matchs your experience. If you get worse temps then turn it back around.
