Hi all, just wanted to ask a quick question about fans….

In my case (HAF 912 Plus) I have an intake fan, exhaust fan, top fan, and cpu fan…these are connected to the MOBO directly (Sys fan 1 etc), and all seem to work fine.

I’m reading a ‘Build your own PC book’ to further my knowledge – and it states:

'We need to provide power to the case's various fans...the cable to do this should of been supplied with the case and will have several rectangular four-pin power connectors on it. These connect to the rectangular white power connectors for the case fan' It then shows a pic of plugging in a power lead into the PSU...

Am I missing something here? Do you need something extra apart from directly plugging the fans into the MOBO – or is that just fine? I mean maybe I have got one, but as I haven’t installed the MOBO myself…I’m not sure.

Or is it just an alternative that you can plug all of the fans into a lead from the psu instead of directly into the MOBO?

Thanks
