Once we flip the card around the dual PCB design becomes a little more apparent. Please realize that you'll need a lengthy PC chassis to be able to fit the graphics card as the tubing unfortunately is not mounted at the top of the card, yet at the back.
I measured it up and it's a fairly familiar length, 30cm /12in.
Right let's have a look at the cooling unit. Here we can see the 120mm fan. You position it at the rear 120mm fan exhaust...
...and then mount it securely with screws. Incredibly simple really.
At the opposing side of the fan we can see the radiator a little better. It's only 120mm and for it to be able to cool down two hard working GPUs, the unit will have to compensate with a lot of airflow. If you look at tubing for a second, next to it you'll spot the pump.
