I have a few suggestions/comments:-
Considering your mainboard is EVGA P55 FTW 200, I suggest you to use the 1st and 3rd PCIe slots for the SLI, if you have not already done so. This provides ample space in between the 2 cards for ventilation. See the 2 green rectangles
in pic 1.
Icy Vision is designed to extract the card's hot air via the rear case fan. See pic 2. When 2 cards are installed with Icy Vision, the bottom card's exhaust will have to flow over the top card in order to reach the case rear fan. It is inevitable that part of this hot air exhaust will be sucked by the Icy Vision intake fans of the top card (smaller red arrows
) while porton will go up through the case rear fan directly (larger red arrows
). See pic 3.
If the rad-fan of your H60 is installed in the case rear fan position, its performance will suffer because the hot exhaust air of the 2 graphics cards will now go through the rad-fan.
: remove the case top 200mm fan and install the H60 rad-fan as exhaust on the case top, preferably in the opening which is closer to the case front in order to be as far away from the case rear exhaust fan as possible. And, if possible, install an additional 120mm intake fan to the front 5.25'' bay to provide more fresh air to the rad-fan in an efficient straight line path.
