If you are not overclocking, I would not water cool your PC. At standard clocks with a standard build, you won't really get any acoustic benefit.

What I do choose watercooling for however is for a clean case and better airflow design which can contribute to increased cooling and decreased noise.

Instead of hanging a giant heatsink with two or three 120mm fans on it off the motherboard and generally being a pain and in the way and also a large weight on your board, I prefer to use the all-in-one water-cooling solutions.

This also allows me to mount the radiator by the 120 or 140mm exhaust vents of my PC and reverse the airflow to intake so that cool air comes into the radiator first, then I can exhaust it to the front or top of my PC. I find that this creates better cooling and also adds to a quieter PC.

Also, I will never buy an Arctic Cooling product for a videocard ever again. I forget what those specific components are called but they are like mosfets and generate enourmous amounts of heat. The AC solution for my 5870 came with tiny heatsinks with poor adhesive tape that constantly fell off or provided no cooling to these units leading to 125° + temperatures which exceeded the operating temperature of these components according to their data sheets. It caused me an enourmous amount of headache and crashes. Eventually the fan controller burned out on the AC Accelero as well and I had to chuck the whole thing in the bin and put the stock cooler back on. A terrible waste of money with poor engineering.
