Nvidia's RTX 3080 design gets stunning fan-made 3D renders

If you look at the curvature of the leading edge of the fan blades, the design feature I would say is best place to tell you in which direction air is to be pushed, it looks as though the fan over the core would spin anticlockwise blowing air into the pcb, and the fan on the backplate side would spin anticlockwise, blowing air down through the card to the bottom of the case. Fans spinning opposite directions, pushing air in opposite directions, but feeding each other.

It just get funkier and weirder and more fake (or in the very least a rejected design) the more I look at it.

you're 99% right. Direction wise of the flow yes. but the fans are clockwise. Check your own fans and you will see based on blade curvature and which way they actually spin.

The inner part of the blade moves towards the air.

I'm sure we're talking about the same thing, just from a different perspective, which seems to be the trouble with this darn thing. lol They say a picture says a thousand words, so this was what I meant by 1 clockwise, 1 anticlockwise

But why would they invert both the fan blade design and the motor direction? The end result is the same as if they'd done neither? The only logical reason they could have to go through the expense of using two different blade designs, one inverted to the other, is if they were using the same motor direction on both sides

IE, if the card worked how you say it does, they could have just used the same fan blades and motor direction on both sides, rather than inverting both blade direction and motor direction (-1 * -1 = 1 and all that)

On that picture there's 2 cards faced opposite ways, so the fans in that orientation will spin in opposite directions, but the same direction if you could look through a single card in action. I think that's where me and warchild were getting wires crossed.

Don't worry too much though, you won't see it on a production card.

Yeah I have no clue why I thought the blades were angled the same, perhaps I saw one photo and then used the new 3D renders. Not the animated one above...
 
Wouldn't this mean either 1) super short PCB or 2) 2x PCB's joined by something that will probably break or 3) standard PCB with the rear fan cooling the back of the PCB??:confused::confused::confused:

NVidia have done this a lot in the past, the PCB is standard but shorter than the card/cooling, so the cooler "overhangs" from the PCB.

Eg: GTX 760 with stock cooler (Image of the back)
