Mining with style!

Anyone know what the pictures say.

I sincerely hope those arrows on the fans are the wrong way around, otherwise this would have a pull-configured fan array with terrible blade geometry for that layout :/

But the blades are also oriented the other way around so it's still pushing air into the heatsink. I think there are other cards which have the same configuration, apparently it creates less turbulence.

ToothlessAnyone know what the pictures say.

just some advertisements saying how the backplate is protecting and designed etc. Nothing leaking or important

Backwards spinning fans, how is that going to help with cooling?

They're going to be extinct just like their namesake.

as a guess about £1100 to £1200 quid on ebay if you want one.. otherwise just dream..

trog

Carcharodon Megalodon, extinct, gone, just pictures and stories. Nice naming, like a joke thrown on our faces

all these 3070 cards look the same lol.

I didn't mean that - it's clear that the middle fan spins a different direction than the two other. I meant the fact that the direction of the arrows is the opposite of how each of those fans would need to spin in order to push air into the heatsink. Fans 1 and 3 clearly have a clockwise fin direction (i.e. with the convex side of the fan blade pointing counterclockwise and the "scooping" edge of the blade oriented clockwise) with the middle fan being the opposite. Yet the arrows are counterclockwise for fans 1 and 3, and clockwise for 2. So if the fan rotation matches what is indicated by the arrows on the picture, the fans are spinning backwards, which would be... rather problematic.

I'm sure the Chinese gamers look forward to seeing these cards out of stock on launch day.

Cool! Proof of concept art! /s

Super duper cool! /s (again)....

I think that is the airflow direction not the spin direction.

ratirtI think that is the airflow direction not the spin direction.

If there is an "airflow direction" (rather than a highly complex flow with far more than one direction) it is into the heatsink, i.e. not something that an arrow could represent well on an image showing the card from that direction. Air obviously doesn't flow the opposite way of the fan blades' rotation - their job is to push air, after all.

Not sure what you are trying to say but air flows the opposite way the blades spin. Blades push it backwards. Are you talking about the mid fan going the other direction the the side fans?

Uhm ... very simplified, axial fans (as opposed to radial fans) create airflow along their axis of rotation. So the main "airflow direction" is into the fin stack. This flow is of course not linear, but rather more of a turbulent vortex shape. Some air will inevitably loop around and flow in the opposite way of the blades' rotation in dead zones with little flow, but the main direction of the vortex is the same way as the fans spin. How would they go the other way? If you push something (like a bunch of air molecules) it tends to move in the direction it's pushed. The fan blade imparts momentum to the air, pushing it at an angle influenced by the blade geometry as well as the direction of rotation. Air does not flow "backwards" from the fan blades. How would that work in terms of physics? Fan blades are essentially shovels shovelling air. If you stick a shovel into the ground and lift it up, dirt does not fly into the ground.

So if you get it what was your point earlier?

The blade are grabbing the are and push it into the heat-sink.
The middle fan spins in a different direction but still same thing applies to it. It grabs the air and push it towards the heat-sink.

Wow, is this really that hard to grasp? I mean, you quoted me on it for crying out loud.

Valantarthe direction of the arrows is the opposite of how each of those fans would need to spin in order to push air into the heatsink.

In other words: going by the blade geometry, fans 1 and 3 are designed to spin clockwise, with fan 2 being designed to spin counterclockwise. The arrows on image 2 in the news post shows counterclockwise arrows on fans 1 and 3, and clockwise arrows on fan 2. Again: you quoted me on this! It's right there in what I wrote! Did you actually read what you quoted? The arrows on the images are clearly pointing in the wrong direction, which is really weird.

You are a hard nut crack bro.
No, it's not hard to grasp for me since I don't have a problem with the design but you do, You don't understand how the fan works but maybe you just can't clearly explain what your problem is? Are the arrows in the picture the problem for you? The arrows show the air flow. Which is opposite to the spin of the fans. Arrows show the direction of the air being pushed by the blades.

Jesus christ. No. Airflow is not opposite of the fan's rotation. That is not how physics works. Imparting momentum on something (such as air) causes it to move in the direction of said momentum until said momentum is modified in some way (friction, turbulence, gravity, other opposing forces). Rotating blades push air in the direction of rotation (not opposite!), modified by the geometry of the blade and turbulence from surrounding objects - but for said geometry to create flow opposite of the direction of rotation it would need some very exotic designs indeed. And to repeat myself for the umpteenth time: I never talked about how the cooler works, nor the fact that the central fan rotates the opposite way of the other two, but the simple fact that the marketing people made a really silly mistake in their materials. It really isn't more complicated than that. I mean ... are we having reading comprehension issues that big? Seriously?

YES!

Valantarthe direction of the arrows is the opposite of how each of those fans would need to spin in order to push air into the heatsink.

Isn't that pretty clear?

I only mentioned blade geometry because that's how we can tell from the images which way the fans are designed to rotate. I wasn't talking about how the fans nor the cooler works. I was talking about the marketing images having arrows clearly meant to illustrate the direction of rotation of each fan (highlighting that the middle one rotates opposite of the two others, which is common for coolers like this after all), but managed to make all of these arrows point the wrong way! Which is silly and amateurish. It obviously has no relation to the function of the cooler, I just pointed out a silly mistake.

Everything is clear for me but for you not. I see no problem with the design or the arrows.
Think about the air flow and the arrows and how else would you have drawn them to show the airflow . Hopefully you will get your answers you seek and get to a conclusion. I'm done here :)
