So I got one of these things for a screaming deal (assuming it works) and I was wondering if anyone was familiar with this variant of the interposer. I know some of them had unpopulated solder points for a 5 volt fan, but I don't see anything obvious on this one. Any ideas?
Mine has a 3 pin header near C22, but the fan only takes two of the three pins. It has a 1998 date on the bottom.
Maybe you could get out the multimeter and see if one of those pinless vias labeled "R5" goes to +5 and the other to ground?

Ok, so got a better measurement of continuity:
Left pad of R5: Pin 3 of VR1, be 5 volts
Right Pad of R5 : A23 or A24
Upper Solder Pad: Pin 1 of VR1, Ground of VR1 used for adjusting Voltage
Lower Solder Pad: Ground
So it'd have to be a pigtail I solder in. Not sure if I really want to do that TBH, I'll have to mull over it.
Not sure, needs checking, that might be a lower wattage mobile part that doesn't need a fan. .... well unless you're trying to break records, then you want more fan than you prolly wanna run off already strained supply to socket.
Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

Most of the chips used on these adaptor interposers were mobile parts. Kingston's was the only one that came with a fan. PNY's didn't but had pads for a 5V fan (it had a really chunky heatsink on it). All the Evergreen chips I looked at had one, too, as did the one shown in the AD, so I was surprised when the seller's pre shipment photos showed a slightly different design (should have asked for pics of the part being sold, lesson learned). I'm guessing the Evergreen part with the fan header is a later revision when they realized that:
1. the tiny HS it came with was entirely inadequate for most cases
2. Everybody was overclocking the damn thing, may as well add a fan header.
I remember reading that some of the early chips like this came without a fan but they were prone to fail, especially in poorly ventilated cases, which is why all of the later ones came with fans.
Mine comes with some cut wires that were soldered directly to the C22 capacitor
Evergreen part G1 rev 1, copyright 1996, the datecode on the AMD chip is from 1997.
Can't seem to find an image of a chip that had the fan connected like that though

Huh, That might be a solid way of doing it.
