Hey guys I have a GIGABYTE EX58-UD5 in an Antec 900 case with the cooler master hyper n520 cpu cooler. When I had one GTX260 I was running @ 720mhz core clock, 1175mhz ram. Now that I've got SLI the top card is getting too hot and I've had to throttle back my speeds. I've toyed with the idea of WC and wanted to hear from anyone who water cools their 260's. What waterblocks do you use and do you like them? And remember I have to make sure it will fit in my case with 2xgtx260's. Also I'd be happy to hear about what WC setups you have and what you folks would recommend for my setup. If I went to WC I would def cool my cpu & northbridge as well. Also I'd rather pay a little extra for quality parts. Thanks for your input.
