honestly I dont think this case is badly engineering from q cooling point of view considering the other ITX designs on the market.
Out of interest, are you driving the fans via a 3rd party software solution like SPEEDFAN or from your mobo and GPU built in software? not sure it would effect your results but I found SPEEDFAN so much better vs my GIGABYTE mobo and GPU offering....
Not sure how other software changes a whole lot. eVGA provides the ability to do custom fan curves - so I can set fixed RPMs or a more aggressive curve. I can certainly lower the GPU temp, but at the cost of sound levels. Right now it's tuned for quiet operation (as it came from the factory). I'm obsessed with keeping things quiet if I can. The eVGA 1070 is a pretty quiet card compared to the 980TI I had previously.
I have a Gigabyte MOBO as well...I have the front fan set to a fixed RPM. I don't really see a benefit to going above 450-500RPMs. Well, I see a benefit to cooling, but not for noise. I could set a curve - but the curve is based on the "system" temps. I've found the system temp hovers around 60C and only deviates a little. It's not really a great sensor to use to change RPMs.
Anyways - I need to install the two exhaust fans tomorrow and try my tests again. It could be the ticket.
