Prototype AMD Vega RX 56 Triple-Fan Graphics Card Pictured

Trying to keep our community entertained and distracted from the growing pains and expectations of waiting for the death of AMD's imposed NDAs on Vega reviews is one of our missions. As such, while we know what you want are actual performance numbers, price/performance charts, and an in-depth, independent review, you'll not find such answers in this post. You will find, however, some interesting tidbits on AMD RX Vega designs. In this case, a triple-fan cooling solution for AMD's RX Vega 56 (the smaller Vega).
A behemoth, triple-fan cooling solution isn't all this prototype model (it does have some debug connectors that won't be found in retail versions of a graphics card), showcased by TooliusTech, has going for it. For one, you'll be forgiven for thinking that is a long graphics card; in fact, it's the cooling mechanism that's longest. As you can see from the pictures, roughly 40% of the added length belongs to the cooling solution itself, with the PCB actually being in line with expectations on a GPU paired with HBM2 memory. Another interesting bit this design has going for itself is the usage of 1x 6-pin and 1x 8-pin power connectors, whereas AMD's reference design makes use of 2x 8-pin. Maybe AMD is being especially careful in their reference design after the RX 480's PCIe power hoggling?

The placement of PCIe power connectors is funny because of the short PCB :D I do like this thingie. One fan blows through the heatsink entirely which is actually a nice feature. I never liked how all heat from cooler is dumped on PCB...

If you have a tower CPU cooler, that hot air will be blown through that cooler and outside the case.

Even if you don't, intake air will circulate through and out the top. Even in my case despite me using AiO. The heat naturally goes up and with the flow of air going through the case. With full length PCB, it is forced to the sides into motherboard and side panel which is worse than this direct pass through.

Having a shorter PCB than the reference 56 is kinda cool.

most side panels come with exhaust fans for dumping this GPU heat.

Looks pretty much like the Nitro R9 Fury , functionally speaking.

Really? all the cases I have had with side panels have been intakes.

I can already tell that this card will run hot

It certainly wont be worse that the reference cooler , if you have a well ventilated case there is no reason why it would not run cool. Cram it inside some micro-ATX case and sure , it will be hot.

every open fan gpu needs a good exhaust on the top or rear (also air cpu coolers need that).... side case panels take intake fan only on closed fan Gpus and take exhaust only when it's open fans like this triple fan gpu.
Also the amount of AF on side panels must be lower than 50 to protect the air turbulence and hot air mixed .
This is my opinion.

Identical layout as my Tri-X Fury. Keeps mine plenty cool.

I wouldn't call that a feature, more like a necessity, since the fin structure has to be that long to properly cool this hot-running card. The short board should go well with mITX builds, but obviously only if water-cooled.

depends.... the config...
Cold air must be inserted down ... and hot air exhausted up...
But.... this works great with closed gpu fans that need a lot of cold air...
The opposite works on open air Gpus these already have fans on the gpu pushing inside the case hot air and this air must be out of the case . So the correct config is push cold air from front ... if it has dust filters it needs fans made for pressure like the ones one cpus not Air flow fans ... air flow fans is used for cases that don't be close to the fan dust filter .
Then we need at least 1 fan top and 1 fan rear as exhaust.
Also most important ,intake must be always 2/3 of the exhaust for example 2x 12 in front at 1.200 ? we need 2x 12 at 1.500 as exhaust... It depends by the size the rpms and the flow... hot air is lighter and we need to take it outsife of the case fast .if we get more cold air than take it out it's worst. Also it depends by the thickness of the dust filters and where they placed... there are a lot of air flow meters o the market ... the best is to place the fans and use the flow meter ... after that use a thermal camera and u know exactly what the hot air is going.
But if you don't want to do that then just see the specs of the fans the pressure the blades if they are open or closed ... the rpms and the size ... write down the flow in and flow out... then take 10% off the flow where dust filter is and you are ok.

I hope this is just manufacturers going overboard with their designs (they do that quite frequently - recently GTX 1060 suffered from the same issue, until EVGA stepped in and designed a card not longer than the PCB). Because I'd hate to see the lesser Vega actually needing this much cooling.

cant tell if sarcasm or...

exhaust/intake doesnt matter, you switch it around to your need. the GPU usually receives air from the bottom or the front of the case.

If only there was some kind of extension to place the power connector at the end of the card.

My only problem is that the third fan is going to throw hot air directly in front of the CPU intake.

An extension that long could never be as sturdy as needed.
I don't have a problem with connectors placed in the middle, the only downside is they add to the height and that may prevent usage in some (few) cases.

My EVGA 970 has similar placement of the PCIE connectors, almost in the middle of the card. :)

Looks very much like a Powercolor Fury cooler on a Vega Nano PCB.
Which also suggests Vega64 variants and means I found my future GPU...
