u/Classic-Wash6417

I finished a build but I don’t know if I need fans on the top or not. When I feel the inside it’s pretty cool though so I think I could live with it. If I do need fans which ones should I get

My motherboard doesn’t have a 3 pin rgb connection and uses the 4 pin one so I have to buy a argb hub which is this one, it didn’t come with a sata cable to connect to my psu and I can’t find one that’s compatible. If there is someone that had this before or can find a cable like this please help. Also the motherboard is msi b450i gaming plus ac just in case.

I could also upgrade the motherboard but I don’t know anything about motherboards I just need it to have 2 nvme slots and am4. That’s just if I don’t want the hub.

This is like the last cable I am plugging in after the case swap but I don’t think my motherboard supports this kind of rgb cable. Is there something I missed?
