No. You can plug a 3pin fan onto a 4pin PWM header just fine. If you look carefully you'll see that the orientation tab is positioned so it connects to the proper 3 pins. The first 3 wires of a 4 pin PWM connector (black red and yellow) are the same as the 3 wires of a 3 pin connector. All they do as add the 4th wire (blue) for PWM support next to the yellow wire. You can also connect a 4pin PWM fan to a 3 pin motherboard header as well as the connector is keyed so that the 3 correct wires are plugged in. You just lose PWM support when you plug a 3pin fan onto a 4pin header or a 4pin fan onto a 3pin header. The fans will run just fine though and you can use the regular fan control options in the bios if you want.
