From the video I believe they are comparing an air cooled card where the fans are powered by the card (so will show up in power draw) against an AIO externally powered.

31W is way too much simply as a consequence if temperature.

What would have been smarter is to just run the AIO card at different fan speeds and then measured the power draw difference.



Flawed test imo. Not like for like.
Indeed. In fact it seems, from watching the build log video, that the AIO they modded onto the Air FE wasn't even cooling the VRMs, so they were running external fans to cool those...

So in short all they did was to measure the power of the GPU (chip only) and pretty much ignored the power to run the extra VRM fans or the AIO cooler.
 
Yet I've read users posting a lot about NVIDIA planned obsolescence... So what is this? They're all the same. We all get the short end of the stick.
Planned obsolescence is something completely different. It's basically a way to ensure your customers feel a need to upgrade at best, and building stuff to break just after the warranty runs out at worst.
 
Yep, water cooling will enable it to hold a stable higher clock, but that also means it will pull more power to run at that speed.

Also, the limited editions appear to be getting the top-binned chips. So don't expect great overclocking on the "peasant" editions.

Where did the binned chips news come from?
 
"Increasing the fan RPM to 51dBA and sustaining about 80-83C on the core, we see that power consumption is around 26A from the PSU, whereas the Hybrid card’s power consumption – with temperatures around 43C – sits closer to the 23.4A mark. This is also largely unchanging from the start of the test to the end, while the air-cooled card scales from about 22A to 26A over the period of the test. After the relatively short burn-in period, the air-cooled card is drawing an additional 2.6A over the hybrid mod, resulting in a power leakage of 31W due to heat."

Does make a small difference, but yeah the pump is probably going to eat into that reduction in power consumption.
Next you'll be telling me that 2 completely different cards running at exactly the same temperature are definitely outputting the same amount of heat.
