Chipset coolers only needed if 1. Your stock one sucks, which generally the ABits do. 2. If you're going for high FSB's not so much just CPU clocks alone.
Bigwater sucks dude for GOOD cooling. high end air solution would out perform it, my SLK-900A and tornado sure does.
If you spend $200
Danger Den TDX
D4 Pump
Tyon Tubing
Weapon 302 core <---heatercore (like a radiator)
then you will have a good performing water cooling setup.
