This is likely normal.
Most graphics cards XFX has made in the last 5 years feature Zero dB technology. Meaning the fans will be turned off most of the time. Usually fans will not spin up until a graphics card gets into the 60-70'c range which will usually only occur when a card is under a load such as a game.
If the cards fans never turn on, even after a gaming load then physically check the fan, make sure the fans spin freely and the heatsink is not clogged with dust.
If you feel you graphics card fans have completely failed, please register your graphics card and file a support ticket at https://support.xfxproducts.com/, in the ticket describe the issue in detail and also provide what troubleshooting steps you have taken.
