Journeyman III

Fans always full speed on brand new RX 580 Pulse 8GB

Hi all, new to the forum but here's the issue I have with a brand new AMD GPU in case someone has any ideas.

Installed a Sapphire RX 580 Pulse 8GB on this system:

5GHz i7 7700k

64 GB DDR4 ram

Maximus IX Hero (MB)

Corsair RM850x (PSU)

My problem is no matter the PCI slot, power cable I use and where I connect on the PSU the fans on the card always run full speed like a mini-jet, from the moment I power up until I shut down. This happens with or without drivers and regardless of OS (fans start at full speed even before the BIOS screen).

Managed to monitor temps and they are pretty low (20-30 celcius soon after startup - if readings are correct) which is to be expected since the card is idle and there are no running tasks but the fans are still full speed, super loud and not as expected to operate.

FYI I tried connecting it on the 6+2 PCI slot on my power supply with 6-8pins, 8-6pins and 8-8 pins cables.

Any ideas of things to try before I RMA this product? Would be much appreciated. Thanks in advance!
