It was a challenge, but I got everything I needed into the 303. With the two 360 radiators, my temps are pretty decent. My 5900X sits around the 65-70C range, game depending. My 6900 XT doesn't normally go above 55C with "Rage Mode" enabled. My fans are set at 80% (1625RPM) and I have my pump at 48% to make it pretty much inaudible. I'm quite pleased with this coolant so far, but we'll see if it holds up with time.
