How do i control the rgb fans?

You should be able to control the fans either with the motherboards lighting software or you can simply connect them to the ARGB controller that comes in the cases. Just google it there’s a ton of info on this case. Hopefully this helped

how many fans does it come with?

I did not buy this specific version. However the tech specs from Cooler Master states it comes with 3 X 120 mm fans. I assume their product info is correct.

Yes, the case comes with some a basic screws, and standoffs kit. CM-PNguyen
