Hey guys,
Sorry for the delayed response. Been busy with all these issues and other things that I completely even forgot I posted the issue here -_-
Anyway, after some extensive testing (taking apart my entire loop and going on air for a little bit, then connecting the loop with individual components, I figured out that one of the GPUs is simply bad. It over heats even at stocks speeds, I just didn't notice (somehow). One of the cards works great, and runs at a cool 38C at 100% load, while the other runs to >80C at heavy load and stock speeds.
I'm just RMAing it.
But to answer your questions:
It is a single loop with a XSPC RX360 rad with 3 Gelid 120 PWM fans.
