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!


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

Your degree of condescension here is pretty staggering, especially considering that you're arguing that fans are managing to break fundamental laws of physics by imparting momentum to something in an opposite direction to the application of force. If the arrows are meant to indicate airflow, whoever made them has no understanding of how airflow works - as I said, axial fans create (mostly) axial flow, not circular flow or radial flow. If the arrows are meant to illustrate the fact that the fans spin in opposite directions - which makes sense, as this isn't something the average GPU buyer is likely to understand intuitively - then the arrows are oriented the wrong way around. I really, really don't understand how this even became a discussion.

The arrows are meant to indicate the direction each fan spins, but some clown drew them facing the wrong way. Simplez.

Exactly what I've been saying since post #4 in the thread
