Instead of purchasing custom cables, I pulled apart the ribbon style wires that came with my SF600. It made cable routing so much easier and too a lot of stress off the connectors. I need to go back in with some cable ties to tidy them up a little more.
I also removed the bottom fans from the case which has actually improved GPU thermals and reduced fan noise. I think that having the fans so close to the GPU was creating turbulence and choking the GPU for air.
Honey, I shrunk the PC
Decided to downsize from a O11D to reclaim some of my desk space (much needed now I'm working from home!).
Tied the build in with getting my hands on a new GPU and moving from a custom loop back to an all air cooled setup.
