I have a Gigabyte 3D Aurora case and they put a pair of fans in the back with a 3-pin connector, but the single fan in front has a 4-pin connector. I would like to connect this to the motherboard so I can monitor the RPM. The only adapter I have found is this one:
However, it specifically states I cannot monitor RPM with this cable. That's lame! Short of removing the Gigabyte fan and replacing it with a 3-pin fan, what can I do to adapt the 4-pin connector to the 3-pin header and still minitor RPM?

Fans that use the 4 pin molex connector for power do not have the ability to report there RPM's to the motherboard. You will ntice that your other fans have 3 wires. As doolittle mentioned above 2 are for power and the third, usually Yellow, wire is what reports the RPM's to the motherboard.
I just bought a replacement fan that has a three-wire connector (red, black, yellow) and also an extension with only one yellow wire connector. I have a fan monitor on my front panel. How should I make the connection? Does ther 3-wire connector plug into the MB, and the yellow wire connector to the fan monitor... or vis-visa?
