There are 4 holes in the heat sink on mine, in a square or close to it.
Each edge of the square appears to be about 40 mm.
The heat sink is held on by two screws diagonal from each other.
The diagonal holes appear to be about 56 mm apart (about 2 3/16" inches apart).

I'm measuring with a metal ruler.

I don't think the heat sink at aliexpress that you included a picture for is the same one unless the measurements they're showing are wrong. They show 182mm long x 100mm wide x 45mm tall.
The heat sink on my card is certainly not 45 mm tall.
It is about 76mm long x 47mm wide and maybe 12mm tall.

Seeing as you haven't tested it, I'd ask why someone went the distance to remove the heatsink.

You have my sword on this, but first things first. You have to solder crystal back in place and wash whole card in water, dry and test it, before planning its future, who knows, maybe GPU has solder cracks and card is in this condition for a reason.

nah alot of times a recycler will rip things like the heatsink off for metal scrap

This is my theory as well, the crystal damage is likely the result of the heatsink being removed carelessly.

All of the Voodoo 3s that I have (4), have heatsinks glued on top of the GPU, as far as I remember. In my cards, there were no pins (like the ones seen on skitter's picture) that secures the heatsink in place. One of them actually came seperated from its's heatsink during shipment. So I would say it is possible that glued heatsink become seperated in some cases, without deliberate effort.

I also looked for fan type solutions from ebay in the past, and will try to check tonight what I have and post pictures and dimensions.

Thank you, this is most helpful. Another friend of mine confirmed that the hole spacing on the board is around 57mm so that checks out. Unfortunately the closest modern VGA coolers are 55mm, so that makes using most modern cooling solutions impossible.

The only one that I am now confident will be enough is this:

The pin spacing is adjustable between 50-62mms so it looks like it would be perfect:

Aside from possibly blocking a one or two PCI slots.

Alternatively there is this chipset cooler that has semi-adjustable spacing, which covers 50mm to 80mm spreads.

There is shorter version without pin legs that I could apply with thermal adhesive tape, though I don't know if these would be adequate for cooling a Voodoo 3?

Another interesting option I came across is this Pentium M cooler which APPARENTLY has 58cm diagonal spacing.. Maybe I should be looking into Pentium M coolers for this job?

Finally, there is this aluminum heatsink block I could buy.. The original heatsink is 75x45x10mm according to a friend's measurements, so if I were to saw 25mm off from one end, then drill the peg holesi I suppose I could, theoretically, fix this onto the card, though with what, I do not know. There is also the question of whether any components on the board are taller than the CPu and would mess this up..

I would greatly appreciate if you could check that. I have found your previous thread on the subject but no link to the final solution you decided on 😀

2 of my v3 3000 agp cards have the heatsink with the pins, voodoo3 2000 cards do not have them and are glued on. The heatsink needs a certain shape because of the crystal and a small chip will be in the way.

I think you can cool the card with a simple chipset heatsink (like the v3 2000 has) but add a fan to compensate for the higher clockspeed of the v3 3000. Lots of people overclocked their 2000 cards to 3000 speeds (and beyond) without issues and stil passive so adding a fan should be more than enough.

So, I just find the pieces and took some pics.

As you can see here, my broken card has a heatsink with no holes, it was directly glued on the GPU before coming apart. But I also found that one of my V3s is a non glue, pinned type.

The distance between the centers of the holes (on card) is 57mm exact. I remember looking for a looong time in ebay to find a fan that fits that spec but never found one. So I bought a 55mm (clear/aluminum circle) and a 60mm (black/copper square) fan.

The 60mm fan fits, but in a quite uncomfortable manner. The 55 mm one fits more comfortably. Not exact, but acceptable.

It's a cheap heatsink fan/combo from ebay, rather on the flimsy side, but feels like ok. Especially if you consider all of the still working second hand V3s, despite the fact that they all were being cooled by just a aliminum heatsink. I also remember buying a converter cable to connect the fan to one of the mobo fan outs, but I neither can find the link, nor the actual cable (probably used in another rig for a completely different purpose 😊 )

First of all, yes, there are items taller than the GPU (the broken crystal for example) and the original heatsink is designed accordingly:

It requres more than just drilling and sawing, as you can see, but if you insist, you can "fix it onto the card" with these:

Thanks for all the info, ended up ordering this:

The fan on the heatsink is rather thick and could potentially block a second PCI slot I guess, so I will replace it with a much slimmer 40mm fan I have lying about. This ought to do the trick just fine, I think..

I would simply drill 2 holes in the original heatsink, sacrifice 2 pins from another graphics card (or heatsink), put some cooling paste on and call it a day.... perhaps put a fan on it or use a big case fan for some good airflow.

And if you want to use a 55mm fan (or whatever size) can't you simply use a drill and make the holes a tiny bit longer? Looks like a small task?

If I were in possession of the original heatsink of course I would do exactly that but I am not..

well id look for a low profile 1u cpu cooler that's wide enough to drill some new holes into, then secure it with 4 bolts, spring loaded with nuts and felt washers on the backside, should work quite well, and be way more reliable than any old pushpin

Ok then, the card is now finally in my hands. After quite a bit of cleaning it looks like this:

Aside from the obvious lack of cooler discussed above, the only material damages I can see are the missing SMD component (labeled R143JNB89, but googling this gives me nada, so if anyone can tell me what exactly I need to replace this with I would be grateful) and slight chipping to the corners of the graphics chip which should not matter at all..

There is, however, this scratch on the back right above the AGP connectors. Visually it looks like it doesn't completely cut any traces, but expert opinion is welcome 😎 I almost had a heart attack when I saw all capacitor pads on the back were unpopulated but my other two cards also have nothing on the back so all is well on that front.

You have little bit more than Voodoo3 3000 Look at ram chips 😀

Are you saying it is a Voodoo 3 3500? Because a lot of Voodoo 3 3000 cards came with 5.5ns memory regardless.

Its 3000. But 3000 with potential for OC 😉

This will run at 3500 speeds easily, maybe more. Not all 3000 cards had 5.5ns RAM.
