2 x 7970 1.4 GH

Nice rig, I am trying to water cool my miner, but 4 VGA water blocks are really pricey, still thinking

Are you using 2 * 240 rad in the loop?
Yes, the top rad is a thin Blackice GT (all I could fit up there) and the front is an XSPC RX240. Cards run at about 60c.
nice, nice, I finally ordered 3 EK universal GPU water blocks and a Koolance 450 pump for my 7950s, but I guess I will need more rad, one 360 maybe not enough for the summer
