Hi I have a Radeon 570 Nitro + Graphics card. I havn't used it for gaming as yet but i have noticed after the initial startup the fans do not ever run. I have used the Wattman and turned the maximum temperature to below that which my system is runmning at but nothing has changed. I just want to make sure they will run once I get all up and running.
Normal on idle for your Sapphire card,
Restore your wattman settings to default and run GPU-Z render test to see at what temp fans start kicking in.
