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?
 

My apology acxcoolerssuck

why??? what happened??
i am someone who dont care about appearance, so bent or broken backplate is fine for me. i simply dont trust the functions of the back plate claimed by aib are practical like better cooling without pads and reinforcing the pcb without linked to the pcie slot. i know lots of ppl really care about the looks so for these ppl you should pick 2mm or whatever the size of the gap is for not hurting the back plate.
 
beside from that, adding pads to back of the pcb will destroy the great look of the back plate, even someone like me dont care about looks and think rgb is stupid, it is quiet disgusting indeed. it may be because of the blue color of the 3m pads, evga may send the black one, should have better look lol.
 
 

Half tempted to tear out the mesh on the back plate and put a temporary fan there myself. Mesh would void my warranty so that's out. But the fan idea i like.

This was the most effective solution i found to cool the back, an AMD processor 6cm cooler connected with pins reversed 5~7 volts, enough to cool and not generate noise.

That's pretty ingenious.
 
My fan setup allows for direct air flow towards the card so it never really gets too top-hot.
 

 
 

I have three fans in the front panel and the middle one blows cool air directly to the graphics card, no obstructions (I removed all the drive cages :) ). But I was wondering, if use the EVGA PowerLink, won't that mess up the air going to the card ? Seeing as the PowerLink will kind of block the back of the card...
 
My case is the Be Quiet Dark Base Pro 900, so it's a beast of a case with massive space.

 Good Question. StijnDC
 
My cards have no back plate so for me it would not make any real difference.

The cooler your processor blows air through the side at the bottom that is has air circulation at the back of the vga you using a cooler there will cool the backplate without problems, any cooler to put on top of the backplate can see the difference temperature only in contact with hands.

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.

 
What? You mean your card's fans pull air through the top and push it down toward the bottom of the case, like in a traditional ATX setup?

Is there actually a model that 'pulls' air off of the heat sink versus drawing air IN and over the heat sink? There's so many incorrect claims being made, it's hard to separate the wheat, from the chaff.

He just gave a hint of what could be done to reduce the temperature.

I remember reading this a few times before buying the card, but forgot all about it till now. Take a closer look at the ACX 3.0. 
The blades are inverted sickle blades that sucks air away from the heat-sink, rather than blowing towards to the heat-sink.
I never got around to verifying which way the fans spun, so if they spin anti-clockwise, itl be towards the heat-sink, and vice versa.

Not that I'm aware of. Considering most people use ATX case designs it would be incredibly inefficient (and you'd probably see worse temps) to have the fans drawing in air from the heatsink then out.
 
Hot air rises so once the air was drawn over heatsink then expelled via the fans it would naturally want to travel upwards as the air is hot. It would then be drawn back into the heatsink causing higher temps and the cycle would continue.
 
Also motherboard design wouldn't really allow this to happen due to the expansion slot layout. Take running in sli for example, The hot air would be expelled onto the back of the lower card increasing temps significantly.
 
So unless you were using a single gpu setup (with no expansion cards occupying other motherboard slots) and an inverted ATX case it wouldn't work. That's an extremely limited market and simply isn't worth tailoring for.
 
I think it was either Gigabyte or MSI who used some self cleaning feature where the fans would spin in reverse for 30 seconds or so during boot to clean the HS. Don't know if they still use this feature tho but it was never practical.
