Enhanced Blower Graphics Card Design

So I suddenly came up with an idea and decided to spend my whole day on it. This thing combines a double fan, tilted fin and a separated video port slot, with no feature lost.

Compare to conventional blower cards, this design gives 150% of cooler fins' area with enough space to mount 4 narrow heatpipes, the video ports are gone so air can pass the pcie shield easily, 2 fans can pump much more air, and that's about it, I guess.

 

I think this board also has enough space to cut 2 some holes for the 2 fans to draw more air from the back of this card.

 

!Please note I did not work with strict scaling, so everything in term of size are wrong.

!Please note those small details are just placeholders to make this drawing more promising.

!Please note that this picture is not made from MS Paint, its made from FastStoneCapture.

!Please note that this could be the reason who drawn this image has trouble to find part time jobs.

 

For the video port cable management, you can actually get away with a group of curved cable in both vertical and horizontal mount. Just like the curved AIO watercooling tubes. You can also add RGB on these internal cables like that glowing Lian Li 24pin power.

Oh shit the left up corner was not connected, r/mildlyinfurating warning...

Unless you expect this card to be significantly longer than a normal GPU you can't fit 50% more heat sink and a second fan, unless you switch to much smaller fans, which have the problem of a much larger portion of their area being fan hub that does less than nothing for airflow.

 

Also are those internal display connections?

¯\_(ツ)_/¯

It is 150% because usually the heatsink is smaller and not even high enough fot 2 pcie slots, and I don't see why you need a fan hub when the graphic card can just control the fan with some circuits

Looks like small fans. Small fans are much louder and have a higher chance of dying due to constantly running at a higher RPM.

Everyone seems to be focusing on it not being realistic, or why it wouldn't work but I say neat!

It's fun to brainstorm these kind of things, and I'm sure there are hundreds of designs that have been prototyped by GPU manufacturers that are similar to this and were scrapped but led to a newer improved design in the end. No need to take it so seriously, it's not like this is actually going to end up being manufactured and it might inspire this person to become interested in thermal engineering.

If you dont like internal cables, you can always add R Gee Bee on it lol

Yeah, but that's the exact same size, 10mm as most blower fans

Very nice but why blower what's the idea behind that? Wouldn't it be much better to have proper fans instead (that cool the whole GPU, you know)

 

Seriously I have no idea why blowers are a thing, I guess price but that's ridiculous at what prices these things are going...

 

But yes, nice concept, I get it 2 = better than 1 ;)

It's because of multi gpu, sfx PC, servers and data centers. Which makes blower design popular. I just put myself a restriction to design a better blower card than any others (that sounded bold but I didn't make it terrible atleast XD)

Datacenter GPUs don’t have any fans

they use the airflow of the case

It‘s still a very interesting design

That's not the issue, and why bother to design, if you don't have limitations?

Final update: 80% more heat transfer area, and took VRM and capacitors' height into consideration, one of those fan can be shrinked to 80mm for a thinner card tho1531584111_pp.thumb.png.cf40ea5b55de3b44afd931e15aa51f22.png

Just add 2 examples of Nvidia GTX 1080 and AMD RX Vega, which shows this layout is totally possible without changing the GPU size, nor the fan size, it's just the layout of other components and cost

At this point I feel blower cards are not using a larger radii fan could be due to it's thickness limitation*, but that can be solved by open up the other side of fan's PCB board completely aswell... so that might give a better design and a smaller card

 

*e.g., air becomes too fast to get to the end of fan blade as blower fans usually runs faster, causing some high pitched noises
