I think this is ordinal fan cable, ie
Yellow +12V
Black Ground
Green Tachometer

I think is not

These might be custom-build headers made specifically for these CPUs?
Wouldn't it be the easiest to simply cannibalize from another slot 1 CPU?
I wonder if the plugs that are used for the front panel header on motherboards are of the same size as the 3 pins on the CPU?

Surely, as mercury said, it's a standard 3 pin (+12V, ground, tach), just the shape of the connector is "special" or proprietary to fit on the board.

Here is a good writeup: http://melectrosoft.blogspot.com/2008/03/how- … k-cable-of.html

edit: though his order from top to bottom is black yellow green, the cable in the picture you posted would indicate the middle pin is for ground.. hmm

If you aren't willing to strip a random 3 pin fan cable and solder it right to the headers, I would buy a broken CPU to take the cable from or a replacement heat sink. Another user here who owns a slot 1 card with the intel fan will be able to tell you the correct color wire to solder to each pin.

Thank You for your answers. I have P III 550/512/100 with cable, and the new one is PIII 1000/256/100 without it. I will take cable from another CPU.

Just solder and insulate nicely a small piece of wire to the pins and add a common connector to the other side

This old thread was the first hit on Google when I was looking for the fan connector specs and pin out. I just bought a P3 600MHz Coppermine CPU and I didn't have a cable for the fan. I was going through my cables and found out that a wake-on-lan cable had the same connector (for the motherboard side). I built myself a cable from an old fan cable and the WOL connector.

The blogspot link above has misleading information on it. The pin out is for the motherboard connector and not the CPU. The correct order for the CPU from top is: fan speed, ground, +12V.

Search ebay for WOL cable for modem and network, they are doubled ended cable with these correct connectors. Cut in half will give you two and splice them to 3 pin plugs for the motherboard.

WOL cable from the network card is used to signal motherboard to turn on with breath of life token data.

Cheers,

These connectors were manufactured by Elco/Kyocera, they are from the 8283 series. They are very similar to the JST PH series but different enough that they are not compatible. They were popular for use in computers from the late 1990's early 2000's. Intel used them on their retail slotted CPUs for the fans (which were usually manufactured by Sanyo Denki), I've also seen them on motherboards for WOL connectors and on SCSI CD-ROM drives for the audio connection. They are a nightmare to crimp using unofficial tools (I wrecked so many of them trying to crimp with Engineer PA-09) and I've never seen an official crimp tool or even found a part number for one, luckily you can still get the crimp terminals and housings from parts dealers. There was an IDC variety of this connector, but they have been discontinued and really hard to find, if you happen to find a source of the 3 pin IDC variety, snatch them up because they could be useful if you are into computers of this vintage.

Hi guys,

same issue for me - my Pentium II 400 MHz came today without fan cable. Quick search gave me this one: 3-Pin Fan Connector to 3-Pin Motherboard Cable / Cord, PC-011. Will it fit?

It looks like it might. I just bought a P3 off eBay thinking it would be easy to find a fan cable, so I'm in the same boat. GoldenPentium, if you buy it, please report back and let us know if it works.

Awesome, thank you that is correct cable.

Cheers,

Yes, it works just fine with Pentium II 400 MHz. I assume it will work with Pentium III too.
