Need help from air flow expert: My case has bad air flow

My dilemma can best be described by the following photos:

As seen, I have a Vivo mid tower with 3 front fazing fans. I have a corsair H100i v2 which I installed the radiator behind these front fans. Following the advice of another, I put the two corsair fans that came with the water cooler on the opposite sides of the radiator facing inwards to create a push-pull effect for maximum airflow through the radiator.

Before I added the two corsair fans, I thought that I didn't even need them.. and was getting around 90C on my cpu which is ridiculous (due to no airflow at all). There was a pane of glass in front of the three fans which was getting extremely hot, and only allowed air flow coming in from the side vents, so I removed the glass and added the two corsair fans to pull air in, which amazingly reduced the max temp to around 60-66C and when idle is at ~33C.

Now that I've solved the problem with the CPU, I'm more worried about the GPU. I've gotten into hobbyist bitcoin mining selling my GPU's hash power for a miniscule amount of money per day. I know I probably spend an equal amount on electricity but I enjoy doing it. When I do this I tend to leave it on all day while I'm at work and all night while I sleep. The temp stays at a consistent 70-73C while I do this.

I know this is a decently hot temp and not dangerous per say, but I'd like it to be lower. If you look at the picture of the inside of my case, My GPU actually has two fans on it that face downward, and my front facing 3 fans lowest-fan blows through the undercarriage towards the PSU (sorry if the picture's arrows are badly drawn I did it on my phone). So the two top fans are already blowing hot-radiator air in and it is being trapped beneath the GPU it seems like. There are very few holes for air to escape out the back ambiently beneath the GPU. I guess what little air is removed is simply sucked out the top fan in the back.

My question is, would it be possible to remove the GPU tabs that cover the place where a 2nd GPU would sit, and put a fan on the outside to increase airflow? I don't have any more places to hook in fan cables so how would I go about doing that? Also with the specific version of the 1080 Ti that i purchased is it possible to install a GPU water cooler? It seems like a GPU water block requires an entire integrated water cooling system, so I'd just be trying to get a water cooler similar to the way my corsair H100i v2.

The GPU:

I'm sorry that this post is so long, but I would appreciate any advice greatly!

Adding the additional fans to the back of the radiator was the right thing to do for cooling, and we even recommend that in the manual (only online right now - printed copies will be included with the next batch).

For cooling your graphics card, mount one or two 120mm fans to the PSU shroud. Position them so they draw cool air in from below and blow directly against the graphics card.

Nice looking system, BTW! :)

1| You've got the airflow diagram wrong. The fans pull air through the fins towards the PCB not away from it.

2| I'm wondering if the front fans are doing any benefit at this point since the given point is that not all fans are meant to be slapped onto a radiator/fins(on heatsinks) since the former would need high static pressure to overcome the densely populated array of fins. Which in essence would mean you pick out fans that are meant to be used on your radiator(which are RGB) or use the included fans in only push.

3| You shouldn't be doing that with your hardware, bitcoin miners have known to sell off their hardware because they know the computational task on said hardware can and will degrade them.

4| In essence you don't need to do anything to the PCI slots as long as you have the right fans on your system to push the air out.

FYI you should be having the system in an open air bench if you're bitcoin mining...
