water cooling 4870s in crossfire

[JTs]

ive got a pair of 4870s in crossfire and want to water cool them. if any one is doing this can you tell me what your using and the temps. these cards will be mildly overclocked. thanks.

You will need a waterblock for the each video card, pump, reservoir, radiator, tubing and non conductive liquid.  If your doing this you might as well get a waterblock for your CPU.  Depending on your room temp, efficientcy of the radiator (single, dual, triple or quad fan), the CFM's of the fans what voltages your throwing at your cards and cpu but all in all you will see a decrease of 5^c to 8~10^c on your processor and more on your video cards.  You may see more.

If your not in a very hot climate, doing high overclocking or have no A/C then the investment in a correct H2O system is not worth the envestment in my opinion.  Two GPU waterblocks, CPU block, pump, radiator, fans, reservoir, fittings, tubing etc your at about 400.00+ for 5^c not worth IMHO if your running stock.

What are the benefits of overclocking?

Overclocked things go faster.

As OOZ mentioned, overclocking your hardware speeds it up. However, there are side-effects. For instance, more heat requiring more air-flow requiring more or faster running fans generating more noise. Don't think speeding something up is simple. While increasing the throttle is simple, keeping it there is the challenge.
