Fan connector cable for IBM PC Server 325

[m62]

Hi all!

I've got IBM's PC Server 325 (model ES0) that i'm building right now.
It's a dual PPro with upto 1Gb ram. It's almost complete except that i'm waiting for memory to arrive and another thing, which I have a problem with.

I've got two Sanyo Denki heatsink/fans with tachometer. They didn't come with any connector cables, what they have is a 3-pin male connection on the side (first two pictures).

IBM's mobo has 2x 4-pin connections for the fans. Well, actually it's only 3-pin connections as you can see in pictures 3, 4, & 5. What I'm trying to find is a pair of cables that I could use to connect the HSF straight to the mobo. I've looked on the iternet for last 4 hours and not found what i'm looking for. Does anybody know where I could find such cable? In the worst case what is the pin out for such connections, so I could perhaps make my own cable?

PS. Yeah I know, I could just use an adapter to connect the fans strait to the PSU, but thats not the point.
PPS. Sorry for the crappy image quality, it was taken with a crappy web camera.

Pictures attached:
Take a look at the connectors!

Thanks in advance!

you dont have the manual for it?
usually it will say which is + and all

in pic 4 i see a "+", can you take a closer look and see if it corresponds to the connector on the motherboard?

No, unfortunatelly both the case + mobo are used and came with no instruction booklets.
Also, I was unable to locate any pin-out diagrams on IBM's website. There is very little info provided on this server.

IMO, the "+" sign refers to the capacitor that was never there.
I can see identical "+" signs next to every capacitor on the processor board.
