3D printer extruder fan not working

[paarth]

I have the Ender 3 Pro printer. I noticed that the extruder cooling fan is not working (fan in the front). Is this normal during printing or is there an issue?
Would appreciate if anyone can help out here .

Thanks.

@paarth Dear, the front fan normally work during printing, is it convenient to provide fault videos? Thank you.
