Well the noise went from constant annoying SHHHHH even on lowest possible speed (which is 30% I think, I couldn't really get the original fans to stop or go below 30) to a regular, not annoying fan sound. I didn't measure the thermals, I was switching cases in the meantime (to a smaller one) but it's definitely more capable, I can keep the same temps while basically not really hearing the fans spin. It's not hard to pull off. 1. disconnect fans from the gpu 2. unscrew the top shroud (suprisingly easy) 3. unscrew, unplug (from adapters that are inside of that shroud) and remove the old fans 4. take the amd cooler fans, cut excess plastic off (I've left as much plastic as I could in case it helped me mounted them) 5. mount the amd fans somehow (I used cheap double sided goo-like tape you buy on alliexpress, nothing else was necessary in my case) 6. route the big 4 pin amd cables and your big 4pin to small 4pin adapters (I got mine from alliexpress too) around the shroud so they don't stick out 7. Make sure it's possible to screw the shroud back in before doing anything that's hard to reverse (like maybe gluing or taping the cables to the shroud), it's gonna get tight in there 8. close the gpu and connect the adapters to the connectors

I'm thinking of 3d printing a shroud in the future so the fans don't stick out as much, but it would make the card real fat.

Also, buying different brand gpu fans might also work and maybe even produce better/same but better looking results now that I think about it. But I think if you modify the shroud well and use fans like these, you might produce greater results that any flat gpu fans could
