Arctic Cooling Accelero S1 (and Turbo Module)
 

It is also worth pointing out that the watercooling loop also contained the processor before the graphics card which would have added heat to the loop and raised the GPU’s temperatures. Lastly, the fans on the radiator were set to 7v which decreased the watercooling performance, but made less noise. Wow, I really am trying to defend and justify my expensive watercooling setup aren’t I?
