Gpu fans stopped spinning after a day or 2

[Sir tablespoons]

I recently finished a build, my first build actually. Things were going pretty smooth those couple days except some minor issues but when I booted up my pc today I noticed that the gpu fans aren't spinning at all. They turn on for a second during the powering on process but then turn off shortly after. I can't seem to figure out how to get the running does anyone have any ideas? The GPU i have is a sapphire nitro+5700rx

That card has a zero fan option on it.  When your gpu isn't running warmer than 55c it won't turn on the fans. Above it, the fans turn on.  Perfectly normal.
