Northbridge Waterblock Recommendation?

[AuDioFreaK39]

I'll keep it short. I have an ASUS P5LD2 motherboard and a Thermaltake BigWater 745 cooling system which cools my cpu very well. Any recommendations for a northbridge chipset waterblock? I'm looking for something under $50. Thanks in advance.

The Corsair Cool Northbridge block is a damn sexy all coper one. I use in on my Asus a8r32.

DangerDen Maze4
Swiftech MCW30
Asetek WaterChill Chipset Water Block North Bridge
or the Aqua computer CS Cooler
