This is my first loop and a pretty standard one. I think I'm done revising this for the moment, I started out with an 3080 Ti and the standard EK D5 Pump and things got out of hand. I used Thermal Grizzly Kryonaut for the dye's and TG-PP10 Thermal Putty to replace the thermal pads, the drain is off a T fitting off the lower port of the intake radiator with the High Flow Sensor 2 on the other side. I am quite happy with the outcome I undervolted the CPU with no performance degradation and applied a slight OC to the GPU, CPU temps don't break 80 C in Cinebench and GPU not breaking 60 C with 3D Mark Timespy.
