Sapphire pulse radeon rx 5700 xt fans not working

Hey there.

Yesterday I have built my first gaming pc with a radeon rx5700 xt graphics card. But when i start the pc the fans work for about 30 seconds and then just stop. I have tried taking the gpu out, unplugging it and putting it back it. The pc itself works just the fans Don't spin... What can I do? Do i need to replace the gpu?

Many modern cards don't run the fans all the time, only when they need to. Do the fans start up when you play a game?

Have you tested a game to see if the fans start working. 

The 5700XT fans don't start spinning below 50 degrees unless a custom fan curve is set.

I didn't know either until I read about it. 

In the end we're here to help each other because AMD doesn't share all the info

I use a custom fan for my RX 480 so that the card is continually cooled, same for my PSU which also runs slowly unless it's loaded hard
