All of the fan connectors on my motherboard are 4-pin, but all of the fans that I have are 3-pin. Can I connect the 3-pin cables to the 4-pin connectors, ignoring the PWM pin on the motherboard connectors?
 
Aye, as RJC says - 3 pin fans will work in a 4 pin slot fine.

There is an off-centre plastic tab alongside each of the 4 pin ports- if you connect a 3 pin fan around this it will all work.
