: yeah we had a mini-debate on this one...

: someone said it was prolly to measure the temperature...somehow. and someone else suggested that it regulated the RPM whenever.

While I don't know for sure about this fan, the only other 3-wire fans I've seen are newer computer fans, and the third wire is a pulse line that is decoded to determine the RPM of the fan...
