So my 3 ASUS ROG MARS cards with 2 GTX 760 chips on one PCB arrived.
I am currently having some thermal issues with the cards not receiving enough air. Some of the fans run 100% and the GPUs still show 98 deg C.
And this is with Yacoin which doesn't max out the TDP fully

Conclusion: NEVER buy a video card with those stupid two-fan coolers!
They may be a bit more quiet if it´s your only card in the system, but as soon as you have a second card, you´re gonna hate them.
