I am a newbie and want to connect my fan that sits on top of heatsink to the power supply. I just want to get some things straight before i begin.

I take the 3 pin wire from fan and connect it to fan sensor header on mobo , then i take the wire with the molex connector and connect it to powersupply's molex. My question is my powersupply has so many molex connectors i don't know which one to use , does it even matter. Some say fan only some don't have a label. Is it preferred that i connect on one that isn't connected to anything else on the other end.

So many stupid questions.

thanks

Which heatsink are you using? If the fan has a seperate sensor then you would connect that to the motherboard. it doesn't matter which molex connector you use to give the fan power. One thing which I would not do is put a lot of components on the same chain.

The heatsink is a SLK-800. So it doesnt matter if say one molex has 4 metal pins and some have 2 metal pins. Or do i connect to one that has the same amount of pins on my cpu fan.

If you have an antec "true power" psuy, the "fan only" connectors will run your fans at just over 5 volts at normal case temps (at least mine do). Plug it into a regular molex for best performance. If it fits, it should work.
