It depends on your gpu, but the space there is 50mm
Sorry I quoted your post and forgot tonanswer my bad
I did think of that to make the fans off centered.
However, I decided against it, due to several issues.
1) is that the fans concentrate the flow to periphery of the circle, and the air expands from there to the form a cone
2) it may make the mounting points weak, given that there would be a large gap
3) I didn't think it would be that efficient
However with all said and done, don't fret! I say, because in the prototype I do intend to make that happen, so far I have ordered 3 different fan brackets
Why 3?
1- centered
2- offset to the side of the component
3- offset to the side of the component with a wide space for the air to come
I will also test it in a inverted position, aka offset on the other side of the component.
Its the usual while I believe something is true, it doesn't mean its actually true, gotta test it to make sure that I'm giving 100% of what the project can be
