PC Motherboard fan connector questions

[Pemalite]

I have RGB. But I have everything set to a white light to match my white case, mouse, keyboard and monitor.

As for fans, it's always good to try and match your motherboard to your needs, that includes the number of fan headers so you can more accurately control them and have them respond to temperature needs more rapidly... Or minimise noise which I have prioritised.

Especially as many cases these days don't even come with optical drive bays to install fan controllers.
