That is a nice rad, Very tight FPI like 16
300 watt load / water temps above ambient
1000 RPM = 9.86C
1350 RPM = 6.39C
1550 RPM = 5.06C
2000 RPM = 3.3C
3000 RPM = 1.87C
You can see where the this tight fin design of this rad lends itself to High speed fans
This would be optimal for you set up, just make sure you have fan gaurds as these bad boys will cut a finger off and at 44db buy some noise canceling headphones
