Took a look and it doesn't look like the AIO will fit in the front above the first radiator. Shame, because that would have worked better. I'm guessing the guys at the PC shop tried this already and had to settle on a pull-push setup
Not gonna lie, it's a little noisy when at load due to the fans, but no worse than air coolers. It's the Noctua fans that make the noise, really. I think if I were to do it again I would get a 3-pin 2000RPM Noctua fan to replace each 1080Ti hybrid fan, rather than bolting the 4pin 3000RPM fan on in addition to the stock fan. That would be quieter than the setup I have now (not quite as good airflow, but I'm sure good enough). I had already purchased the 4 pin, so that's why I did it the way I did (for a direct swap it must be 3 pin).
Thank you sir!! Much appreciated
