Posted this in the xXCrossXFire ClubXx section, but figured it deserved a cross post here.
Added some H60 DIY water cooling to my Sapphire 7970's until I can sort out the issues with my H220. I fixed the tubing from the top card pushing the bottom card down after I snapped this picture. My computer is now almost completely silent when gaming!
Here are the temps with 2 Gentle Typhoon AP-15's in push/pull for the bottom card, and one in push for the top card. The fans are running at 40% or so on a fan controller at all times and the H60 pumps are running at 80% to avoid the H60 pump grind.Top Card

The Sapphire cards already had heatsinks on the VRMs, and the VRM temps seem to be about 3-6C cooler than with the stock heatsink / fan. This is with a Fractal 140mm fan blowing on them from my side panel at 40%.
