It's EVGA's fan controller going totally haywire.

It tries to get the performance up... by increasing fan speed to 6 digits. This results in the fan #1 spinning at above 100% fan speed, yet it's still not enough to reach what the fan controller tells it to do, so it pulls enormous power trying to reach what it's getting told. Enormous power as in, pulling a comparable amount to the GPU chip itself. Of course the fans can't take that for more than a few seconds, and even the boards struggle with so much current flowing through them.

Also, they are calling out EVGA for saying that since the patch, it doesn't happen anymore, but it still does, as their test and the screenshot with those 6-digitfan speeds are from after being patched.

Finally, it's not just New World. It also affects their cards in other games, like Anno 1800 for instance. In their test, Anno often made the fans spin up to 100% and dropped down again immediately after. But rarely, the fan speed didn't drop down, and the PSU's overvoltage protection stepped in and shut down the PC to save the hardware.

tl;dr: Don't buy EVGA

Thanks for the explanation!

You're welcome.

One thing I didn't mention before is why NVidia seems to be more affected despite EVGA making GPUs for both AMD and NVidia. It's not only due to market share, but on how and where power gets measured.

AMD measures power directly at the gates of the GPU, while NVidia measures all the incoming and outgoing electric transmissions of the card. This not only results in different ways to define the TDP or TGP of their cards, but also how fast these measurements are. IN AMD's case, they're very fast as they measure at the source and can immediately act on it, but can nontheless get overwhelmed, especially with higher clock speeds outpacing the controllers.

NVidia's way of measuring everything coming in and out of the card instead of the GPU proper is coming with a natural delay. This delay is at the source of the ramping up the fans to 100% and then dropping down again almost immediately after.

And while I have no proof, I do think that if the controller gets overwhelmed while ramping up to 100+%, it stays that way and causes the bricking of the cards unless power is cut in time.
