if that little pads are for cooling, then i think evga should have used the same gpu pad in arctic hybrid 140.

 
Wonder if this is as good as it gets short of liquid. https://www.arctic.ac/wor...ccelero-xtreme-iv.html

One thing that hasn't been mentioned or covered much in testing is how the fans pull in reverse on the ACX 3.0 instead of push. 

Warm/hot air rises so you would only be recirculating the hot air unless you owned an inverted ATX case.

It all so looks like this will block air flow between your PCB and Back Plate.
I would re-review what you are doing here and also use the correct size of them pads as you do not want to bend the Back Plate.
This may lead to bending the PCB and even cracking the PCB.

i dont give a care about the backplate being bent. you should choose 2mm pads or you can measure the gap by yourself.
 
you have the mid plate and pcb is tough enough too, i dont think slightly bent backplate will hurt the pcb. 
 
if heats from vrms of the back of the pcb spread to the backplate, why do you need airflow to the gap?

speaking to gpu cooling, there is no way air coolers can beat aio.
although this cooler from arctic can kill most of the stock coolers from aib.
palit jetstream and gainward phoenix coolers are insanely powerful, hopefully i can see evga coolers to meet that level in future.

The first thing that came to mind was reversing the side panel and floor fans to exhaust.

dont miss this part too. i dont know whether the pads will be sent by evga would have covered this too, just dont miss that.

That's why i said "short of liquid". Obviously a custom loop would be an improvement, but i think it may rival 120mm hybrids.

reviews of evga hybrid and msi pascal seahawk like gamernexus show you 120mm rad is powerful enough for heavy overclocking like ~300w. 

Yeh fair enough i don't doubt that. I don't read into them, as i prefer passive GPU's. I put liquid on my CPU's tho.
 
End of the day, no-matter what card you talk about, you always have 3 main components generating heat of their own.
GPU, VRAM, and VRM's, and its up to the manufacturer to strike the right balance of heat distribution from those
components, to the right available areas of the cooler to maximize its effectiveness. I'd hate to be the engineer that's
responsible for this task. There's a lot at stake and getting that balance wrong would be quite a concern for them.
