Here's the image EK have on their cooling configurator when it tells you they're compatible:
This is how the VRM section on the Galax looks, note the different and badly aligned chokes have invaded the space of the VRM's and forced the factory heatsink to be installed away from some of the VRMs (oh, and apparently the die had more TIM squished out around it than most people put on their entire CPU in case you were wondering what's going on to the right lol):
And here is a shot from above without the heat sink showing the full scope of the problem, the different and badly aligned chokes are so far out of position they are basically in the VRM zone:
From what I can see the sad point is even though they use different chokes, if the factory in China had installed them in an organised way in the right place they would still have fitted in the gap for them in the water block
