GPU fans don't spin unless under load?

[Sharks445]

Hello, I have a Powercolor PCS+ r9 390 and I noticed that the fans never spin. On idle the temps are around 37-49 and load is usually 60-65 (75 on stress marks).
I noticed the fans only turn on when I play a game. After I stop playing the fans turn off, even if its at 50c.I can manually set the fan speed to go flush out the hot air, and temps will then stay at the high 30s on idle. Is this a major problem? The idle temp is usually in the low 40s when the fans completely stop, and usually stays there. They start up once I start hitting 60c when I start a game. Changing the fan curve on MSI burner does nothing, so I believe the fan thresholds are deeply embedded in the BIOS

Idle fan noise is fantastic as the card completely turns its fans off in idle (up to 60°C). Light gaming does put enough load on the card to make the fans run at all times, though.

This is how it meant to be. No worries. Your temperatures are fine.

You're fine. That video card (and many others) dont spin up the fans until the card hits 60c.
