ASRock Launches AMD Radeon RX 7900 Passive Series Graphics Cards
ASRock, the global leading manufacturer of motherboards, graphics cards, mini PCs, and gaming monitors, today launched the first passive series graphics cards -- ASRock AMD Radeon RX 7900 XTX Passive 24 GB and ASRock AMD Radeon RX 7900 XT Passive 20 GB graphics cards.
ASRock Radeon RX 7900 Passive series graphics cards are powered by the AMD Radeon RX 7900 XTX and Radeon RX 7900 XT GPUs. Both of these two cards are supporting multi-GPU collaborative computing, and designed for multi-card parallel computing for better performance. ASRock AMD Radeon RX 7900 Passive series graphics cards are featuring a VAPOR-CHAMBER heatsink, efficiency aluminum cooling fins with v-shaped cutting. Furthermore, thanks to the single horizontal 12V-2x6 power connector, to install couple of ASRock AMD Radeon RX 7900 Passive series graphics cards become much easily due to less power cords.
In additional, ASRock AMD Radeon RX 7900 Passive series graphics cards also have a metal backplate to provide solid construction. Undoubtedly, ASRock AMD Radeon RX 7900 Passive series graphics cards are outstanding choices for systems integrators.

"the blower fan of ASRock Radeon RX 7900 Passive series graphics cards"
Passive? No.
Blower fan pictured? No.
250W GPU cooled without a fan? No.
Please Asrock, do better. These are GPUs for rack-mounted servers with forced chassis airflow. Using them passively will result in abysmal performance, if not rapid damage to the card. No SME or creator wants this in a workstation that sits within earshot of a human. We're talking 65dBA of screaming delta fans and this is a server-room or datacenter GPU.
I wish companies would make single-fan blower GPUs again. They fell out of favour because manufacturers stopped at 2-slots wide, which is stupid because even dual-slot open coolers need 3 slots of space, so a blower design equivalent to a 2-slot open cooler is 3-slots wide. Now that we have GPUs needing 3 slots and a 4th slot to breathe, I would love to see a 4-slot blower design where ALL 300W of the heat are spat directly out of the back of the case, none of this recycling hot exhaust air nonsense that we have with today's gargantuan open-cooler designs.
There you go.
Most 7900-series cards are 2.5 or 3-slot designs, so the equivalent blower should be 3.5 or 4-slot blower.
That piddly little thing looks like it's going to struggle with a 200W TDP at any fan speed, let alone acceptable noise levels - the heatsink fins aren't even full length!Not as useful as you think. The static pressure of an axial fan is nowhere near enough to drive air through such a long column of fins, hence the radial/centrifugal fans normally fitted to blower-style coolers.
When you see a pressure-optimised axial fan like the Phanteks T30 or Gentle Typhoon, they're geared towards a 20-30mm radiator or air-cooler's tower stack, and you still have to double them up or push-pull to get the best results. The fin stacks on these blower cards are usually 5-10x longer than that, and turbulent airflow for efficient heat exchange drop off with distance according to an exponential decay curve.
As a rough figure, the "pressure optimised" axial fans have 2-3x the static pressure of a typical case fan, but for a blower you need order(s) of magnitude (50-200x) more pressure. 2-3x more pressure might as well be nothing at all. Take this with a grain of salt because these are only my rough estimates but I do have a background in computational fluid dynamics, even I'm pretty rusty.
I just plucked that from the eWaste recycling pile behind me - but as far as I can remember these cards were whisper-quiet and really damn effective.
I wish we could still use AMD GPUs but CUDA dominates the software scene so totally that nothing except Nvidia is actually useful to us.
Well, I guess I was technically correct (the best type) since the same chip and all, lol. But yeah, the current situation is abysmal and something tells me it won’t improve next gen. I absolutely wouldn’t be surprised if NV again releases 8 gig cards into mainstream with a bold face and acts lile nothing is amiss.
(I also would love to see this tested in a normal case just to be funny)
Just unplug the fans on your XTX and watch it cook at it rapidly climbs to the hotspot throttle temperature and just sits there forever! ;)
