To SDatl404: We know, koolance, under those conditions, will perform better. That's not the point though: Answer me this: Who runs their watercooling systems with 300+ CFM fans, with water at 85c + ? The tubing isn't even rated to that high. Crank it down to realistic values: 35c water, <100cfm fans. You'll clearly see that the HWLabs and Thermochill will outperform the koolance.
