So I just completed a custom loop on a Corsair 7000D airflow with the following loop:
D5 pump, 360mm rad, 420mm rad, 7900XTX and 5800X3D
However after 1hr on microsoft flight sim I got these temperatures that seem high to me (mostly gpu):
Ambient temp 29C
Water temp 41C
Pump speed 4850 RPM
CPU 65C
GPU Hotspot 81C
GPU 57C
I'm pretty sure that the paste was well spread since I used the KPX and used the spreader to make sure it was done correctly on both the cpu and gpu, all the fans are at 100% and the radiators are warm to the touch
