So this machine has been in the months coming (built last year) It is meant to be my dream workstation. It was the first time I did hard tube watercooling.
This build has 4 480GTS HWLabs which I had to cut the sides of the radiator frame to fit since HWLabs is much wider. It has 16 fans in the front radiators (Push-Pull) and 8 fans in the top radiator (Pull) and 2 rear exhaust fans, with a total of 26 fans in the main build. I do know this is major overkill but it was something I wanted to do nonetheless.
Cable managing was a pain, with 52 cables from the fans alone(RGB + Power) I ended up using 6 corsair commander pros in the back to manage these, basically one COPRO for each set of 4 fans.
The cables are extension cables from mod-one, in white black and white grey.
As for the loop, it is a dual parallel loop, the top radiators are for the CPU, while the front radiators are used for the GPU( I might add another RTX 2080TI, IDK).
The mini ITX is an 8086k running freeNAS(yes I know, but I already had the parts), used mostly for plex + raddar/sonnar
Cable management was a pain. I was not able to get 128gb ram to 3200mhz so I settled for 3000, who knows perhaps in the future. Had to reorder some Commander Pros since some came dead on arrival.
I was able to run the 2990WX stable at 4.2ghertz but ended up leaving it at 4.0, idle temps for CPU is in the low 30celsius and while under load I have not seen it over 50celsius, with that many radiators I was able to maintain 60-65 celsius under load with the fans off, basically passive cooling.
I haven't played with OC the GPU yet, but it is the same, very cool however passive cooling is not possible.
All in all, this was a fun build to do, a total overkill and I would most likely never do it again. But one must realize their dreams!
