Hi

I am building a new pc (firs one so a noob), the Antec 902 has 4 case fans. I have connected these to my PSU(be quiet dark pro 650w).

Do these also have to be connected to the mobo?

Thanks for your help!

don't think so unless they are controlled by software you got with the case

I found that because the power to the fans is controlled by a sensor in the PSU that they sometimes didn't spin up so mine are either plugged into the motherboard and controlled via the BIOS or through molex/fan adapters like these click here

I think you have fan controllers to adjust the fans speeds on the case so would be better making sure they have a full 12v.
