Alpha UP1500 CPU Fan

A month or so ago my cpu fan started making a grinding noise and I decided
to go ahead and lubricate the cpu fan in order to get some more additional
life out of it before having to replace it. Well the time has come,
unfortunately I lost the little sticker on the fan with the model and specs.
Does anyone happen to know the fan specs or where I can find a replacement
80mmx15mm fan?

>From what I was reading, it will require a little require a little rewiring
of the pins on the fan. I appears that instead of using the 3 pin for
pfan_sense, it uses the 2 pin. I've tried several 80mmx25mm fans but it
seems the "System Fan Controller" is a bit sensitive to voltage/resistance.
