A basic fan connector question

I searched for a more appropriate newsgroup for this question but couldn't
find any so I hope it is appropriate for this forum. Please suggest an
alternative if it isn't.

I am building my first Intel-based PC and am having a spot of bother with
the system fan. The case has a single fan at the rear with a cable attached
and a 2-pin plug at the end of it. The fan connectors on the motherboard
are all 4-pin. How do I connect the two of them together? I have tried
putting the 2-pin plug on to pins 1-2, 2-3 and 3-4 of the motherboard
connector but it doesn't work. I suspect the power probably comes from pins
1 and 3 or 1 and 4 and that the other pins are used for monitoring. Is this
correct? Do I need to do a bit of soldering or altering of the cable and/or
connectors?

Thanks,

Wes

New board ?

If it is then the connector will be PWM Fan Connectors.

Probably worth your while buying a PWM fan which the mainboard will be able
to control.
