So after looking at the card, vs reading the guide, while installing the block, I'm genuinely confused, post install, as to whether or not my card is actually setup in the correct "recommended" way or not.
 
I know the guide is semi-generic in some ways and specific in others to the card you have, but the guide has this:
 

 
But then the block has these little "triangle" "arrows" that my brain just assumed is meant to be flow direction indicators that literally contradict the "recommended" layout:
 

 
My main question is just that - is the Guide correct on & the Inlet being closer to the NVLink Bridge is correct, and those "triangles" aren't meant to be flow direction indicators at all, or is the guide wrong?
 
Also, the nook area that's circled in the picture, does that sort of impede flow?  I think I'm thinking too much of how airflow works as opposed to water/liquid.
 
Also, why is it on the Kingpin HC block that the design (if you're using the stock KP backplate) makes it impossible to actually DO an inlet fitting on the port closer to the BIOS switch?
 
 
Oh, picture of the system's setup for reference: 
 

 
She's a bit of a tube-nest, but the flow is pump --> cpu --> radiator --> gpu --> radiator --> pump/res - so the Inlet is currently on the "left" top port on the card in the picture... is that right for the "recommended/ideal" setup? 
 
 
Am I the only one that saw those triangles & didn't go "are those flow indicators?" lol  I know I was loopy Wednesday during assembly but I hope I'm not the only one that made that connection.

    I think as long as you use one side as an inlet and the other as an outlet you are good to go.

    GPU waterblocks don't really have a direction unlike CPU blocks, where the water from the inlet hits the jetplate directly at high pressure, so it cannot be used as an outlet.
    You can do anything as long as you don't provide a direct path for the water to bypass the GPU completely which is shown in the 3rd and 4th images. You can even have the inlet at the bottom left and outlet at the bottom right, or top left and top right. If you have two GPUs you can even have them in parallel, which is a valid configuration even though half of the water flow bypasses GPU 1 to go into GPU 2.

    All these show flow going from top to bottom can that be reversed?

    IE I want bottom left as my inlet and top right as my outlet will this be the recommended setup or not?

    I’ll have to redesign my whole loop in it has to go top to bottom

    Have you ever tried to swap inlet and outlet?

    GPU waterblocks don't really have a direction unlike CPU blocks, where the water from the inlet hits the jetplate directly at high pressure, so it cannot be used as an outlet.

    GPU waterblocks of the impingement design with a jet plate do.
    You can't just make a generic statement claiming that no GPU waterblocks use the same design as some CPU waterblocks.
    I agree that this waterblock doesn't appear to be designed in a way that it should make any difference which direction the water flows.

    Inlet and outlet of this waterblock would perform the same. The fin pass through design is non-directional.

    The only time the inlet/outlet would matter is on waterblocks with a jet plate that forces flow from the center of the fin outward. This block does not do that.

    *edit* Ty_ger07 posted while I was busy and is 100% correct.

    EKWB uses the impingement design, and even they show that flow path is a 1-2% difference if you reverse the flow. In the end, that isn’t much.

    Follow the directions of the manufacturer. In the EVGA waterblock case, either side is an inlet, and either side is an outlet.

    Note, that the "Arrows" you are referring too are not meant to be flow direction arrows.  They are flow diverters that are intended to split the flow water as evenly over the entire block surface as possible.  So the diagram is correct.

    I run mine in the recommended pattern.  The only reason I could think of why it would be reverse is if for some reason your video card pump was on the left side of the video card.  But who knows what people are doing out there.  I know my build was nutso...
