Ryzen 5 3600 fan not working

Hi all, just building my new rig.

Msi b450 gaming Pro carbon ac
Ryzen 5 3600 with stock fan

The fan doesn't seem to spin at all, yet if i connect an old fan it works and the bios detects the spinning speed.

Temperature sitting between 45 and 50.

Any help would be great. All parts brand new

Forgot to say it all boots up into windows fine. But I then turn it off due to the fan not working, just incase.

Should the fan start straight away?

I've checked the bios and the lowest temp setting for the fan is 20 degrees, so I assume it should be on!?

That's correct yes sorry.
Is it safe to run whilst the fan isn't working?

Yes it's the stock cooler.

It seems very odd that an older fan works and this one doesn't so I presume the new one is dead
