Question RX 580 but something weird.

[Bigbry]

The display and performance of the SAPPHIRE RX 580 are working well, but there's an issue with the fan not spinning. I've resorted to using an external fan blowing through the side panel of my PC to compensate for this. Additionally, the LED on the Sapphire card isn't lighting up. What could be the underlying problem here? It's worth mentioning that I've recently replaced the fan.

Welcome to the forums, newcomer!

It would probably mean that the card might need replacing. At the very least you're adept with circuity, perhaps see if the part that manages the power to the fan is needing replacement.
