Inspired by @DrAwesome95 , but lacking access to any sort of laser cutting at a price that made sense, I had a fan panel 3D printed to go on top of my RVZ02. I added 3 slim 80mm fans from Coolermaster, 3 wire fan grills (because they make the least noise)
, a Zalman Fanmate2 rheostat to keep the fan speed and noise down, and I run the fan setup off of the fan header located on my Asus Strix 1070 so that they only spin when the GPU is over 60 degrees.
The results are a triumph. Before the mod, the GPU would hit 80 degrees and throttle after 3 minutes of Unengine Valley. Now I have it overclocked and volted, and it never goes over 72, and it's still barely audible.
The only issue I had was that the 3D printer had a length limit of 316mm, so the panel couldn't reach the front screw holes.
