Hola I have a question since it will be my first build and I don't want to mess it up, my question is, how do I know how many fans my motherboard supports and how many do I need it is a question I had for a very long time but can't get an answer. So I know the case has two preinstalled and the aio has 2 more fans so do I need 4 connectors, should I buy a Usb Hub cause supposedly the mobo has 3 but I only find 2 in the specs if someone can answer my question it would be awesome, thanks.

According to ASRock

 

- 1 x CPU Fan Connector (4-pin)***
- 1 x CPU/Water Pump Fan Connector (4-pin) (Smart Fan Speed Control)
- 4 x Chassis/Water Pump Fan Connectors (4-pin) (Smart Fan Speed Control)****

You can zoom through the board on this page to see where the respective connectors are. Looks fine to me with your needs

So I am sorry for asking what connectors am I looking for exactly?

Like how many of each do I need

And the motherboard you linked is not the same one

Be aware that the benefits of SLI (assuming you don't need the GPUs for productivity workloads) does not really make too much sense any more (see a recent LTT video regarding that topic on RTX 3000).

It sounds weird but that is the name of the gpu and dual as two fans not two gpu's
