I decided I was unhappy with the ML140 fan noise with just the 420 + 140mm radiators and was bored during quarantine. Ended up making an external radiator/pump setup to add some additional cooling. I have a MO-RA3 on another build and considered buying another, but they can be hard to find in stock and I had 3x 240mm rads laying around in storage. Bought a Phobya rad enclosure and an additional 240mm barrow rad mount on top. Connected it all to a scrap of wood. Fans are Arctic P12 connected to a Splitty9 connected to a Poweradjust3 Ultra. Since I had 10 of these fans, I used all 9 ports on the splitty and did push/pull on half the radiator area. It has a G1/4 temp probe connected and runs all the fans based off liquid temp. After a momentary startup boost, they settle at 4.1v which puts them at 715RPM and is almost completely inaudible.

The system is now always at single digit water/air deltas while being very quiet.

I also added another 32GB of B-die and swapped the "clear" fluid for Mayhems UV Pink while I had things apart.
