Question Case fan not spinning

[Sgt.Crawer1116]

I just bought a new PC, custom built at a local store, and it's specs are the following
Geforce RTX 2060 6G
Intel i5-9400f 2.90GHz
Gigabyte h310m H 2.0
Spectrix RGB 16GB 3200MHZ
SSD Crucial BX-500 480GB
Don't remember exactly the HDD.
Finally the case is a DT3 Edge Glass, which came with a fan.

The issue is that the case's fan isn't spinning. It seems to be connected to the power supply. Anyone know what's the standard installation of this fan? Should it be connected to the motherboard?

You can connect the fan (non RGB) either into the MB ( sys-fan header) or to the PSU. But if the fan has 4-pin connector, you should connect it to the sys_fan header on the MB.

Recommend to go back that local store let them check it out. In case the fan has problem, you need the replacement.
