Info: My love for space-optimized PCs came at the cost of noise and thermal limitations. I decided to design an external radiator with quick disconnect coolant lines. I was able to score 96th in the world for a single GPU on a popular 3D benchmark called 3D Mark Time Spy out of 12 million runs.  My GPU core will max out at about 48c when pulling 470w and CPU 74c at 250w!

Specs: 

• PC standalone is 5.9L in volume (shoebox size!)

• Radeon RX Reference 6800XT (power/volt reg edit mod) 2750mhz Core 2150mhz Ram  @ 1.25 Vcore

• R9 5950X 4.65GHZ @1.3 Vcore LLC mode 4 

• 32GB 14-15-14-39 3800mhz @ 1.5v DDR4 Samsung B-die based dual rank kit 

• MSI B550i MPG Itx Motherboard

• SX750 PSU Noctua mod + Custom wiring (due to space constraints)

• 420mm Hardware Labs GTS Radiator

• 3x Thermaltake Toughfan 140

• Heatkiller AM4 water block

• Alphacool RX 6800 XT water block

• Alphacool D5 pump

What I learned: I learned just how important good cooling is for pushing my computer to the absolute max.
