The Nvidia GTX-470 was overclocked a bit with our DD-GTX470 block. At max voltage I was running 850/1700 on the GPU and 2000/4000 on the RAM. This was using the simple Black Ice Pro II radiator and a CPX-1 pump. Max temp was 53C. So, you get a massive overclock with this video card!! Check out the video on YouTube.
Have you ever wanted to power up a pump or a fan quickly? Didn't want to open your case to do it? Or you just finished installing the liquid cooling system and now you want to prime the system without using your main PSU?
