Gtx 1050 ti fan not working

[famillesavor]

I recently bought the evga gtx 1050 ti and for some reason the fan won't start. I have tried softwares like evga precision or msi after burner but even at 100% ( pressed apply btw ) it doesn't start. In games it still runs good but reaches temps like 90 after 20 minutes without the fan starting.
Should i return it or is it a mobo/bios/voltage,etc problem???

I am looking into that but what if ( i know right? A what if!! ) when i get the new one it does the same thing? Could it be eelated to anything else?
