If you're looking for an ITX sized card, you now have another option from PowerColor.

Their Radeon RX 5600 XT ITX card comes in at just 175mm long with a reference height of 110mm (including the PCIE connector)

https://www.powercolor.com/product?id=1582011980

It ships with 14Gbps GDDR6, and a slight overclock of 1560MHz(Game)/1620MHz(Boost).

I can only currently find it for sale at Scan Computers for 299 pounds:

Lets hope this RX5600 XT VBIOS supports UEFI GOP (Unlike their RX 5700 ITX which shipped without supporting it).

Would be nice to get a low-profile Navi card one of these days. Is it because there's still no model that can be fully powered by the PCI-E slot?

Even the Radeon RX 5500 draws 100-120W, which is around the same as a GeForce GTX 1650 Super. Unless a Radeon card with 75W or lower power consumption is released we probably won’t see any low profile cards.

Currently, the GeForce GTX 1650 is the most powerful low profile card available. Hopefully the GDDR5 models will be replaced with GDDR6 models soon. They should run 5-10% faster even with slightly lower core clock speeds to keep under the 75W limit.

Anyone buying one of these make sure you watch this video.

The video says that somehow fan RPM goes down when GPU hotspot is still high.

But what is "GPU hotspot"? It can be a mosfet or choke, which, IIRC is made to handle 105°C right?

Fan curve is usually based on the GPU core temperature, not the mosfet or choke temperature.

The GPU hotspot is also sometimes called the junction temperature. There are many temperature sensors built into and spread across the GPU die itself.

Where we normally see the GPU Temp as an average of the values recorded by all of these sensors, the "hotspot" is the highest temperature being recorded by a single sensor.

This was AMD's official statement on the matter when it was brought up during RX 5700 testing:

"Paired with this array of sensors is the ability to identify the 'hotspot' across the GPU die. Instead of setting a conservative, 'worst case' throttling temperature for the entire die, the Radeon RX 5700 series GPUs will continue to opportunistically and aggressively ramp clocks until any one of the many available sensors hits the 'hotspot' or 'Junction' temperature of 110 degrees Celsius. Operating at up to 110C Junction Temperature during typical gaming usage is expected and within spec. This enables the Radeon RX 5700 series GPUs to offer much higher performance and clocks out of the box, while maintaining acoustic and reliability targets."

Still, the manufacturers need to have appropriate fan curves set even if a temperature this high within the core is "expected and within spec"

Another difference in Navi vs. other GPUs is that thermal sensors are distributed across the die rather than just being located around the edges of it (AFAIK all other GPUs from both manufacturers only have edge sensors). This allows for more accurate temperature readings but also makes them seem higher (there's easily a 10C difference between the GPU edge and middle). This is also why AMD implemented its hotspot reading, as that simply represents the single hottest sensor at any given time. Still, even these temps should be kept in check, and if the board gives off fumes and noxious smells when it gets hot, there's something wrong somewhere. And that fan curve makes no sense whatsoever.

Beyond that though, this seems like a really nice GPU. Here's to hoping PowerColor fixes the fan curve. It would make for a fantastic upgrade for my OptiplRX 570 down the line.
