This looks adjustable like the old Zalman passive NB coolers and fit Voodoo cards as a consequence.
Haven't tried this copy tho myself, but it looks like it should work, risk it or not 🤣 . With the fan off its gonna take up an extra PCI slot or 2.

You still have the Voodoo 3 heatsink? is it the silver wide type? or pin type? You can just get some Plastic clip\prong springs if its the silver type, assuming you lost the gold ones that it came with if it had that type of heatsink.

Otherwise just find an OEM Socket 5\7 passive heat-sink, the Pin type that come with many of OEM machines and make great passive Coolers for older Vcards or low profile one with a fan can also work. If you want even more cooling, and glue that to it with your choice brand of thermal epoxy.

I wonder, has anybody found a perfect fan for Voodoo3 3000?

just get some thermal tape/adhesive and any cooler with a fan will do.

Cheap as chips Cooler mod for Voodoo 3 cards!

Video guide:

3dfx Voodoo 3 Cooler

Why?

Voodoo 3 cards are known to run very hot and come with a passive cooler only

Benefits?

- Cheap
- Card remains intact / resell value

What do I need?

- 80mm fan
- 1 thin cable tie
- 2 rubber bands

For those who don't like watching videos:

- Place fan on top of card
- Put the cable tie through the bottom right hole on the fan and cooler.
- Tighten cable tie and clip off remaining part
- Secure the left side of the fan with two rubber bands

I've seen your video Phil, but I think you went with a fan that is just too big. I am trying to see what is the right fan size for Voodoo3 3000. It gotta be 40mm. Now just need to find a decent one that will last.

I just ordered this thing here, I hope it will keep my Voodoo 3 3000 cool enough:

It sucks the air in and blows it out at the back of the PC, so theoretically you can cool every GPU with that one without meddling with heatsinks, rubber bands and fans. I'll let you know if it works!

This is my modefication.....
As the original heatsink has 4 holes, and only 2 are used to mount it to the pcb, there are 2 holes left for zip-ties. You only need to find ones that are thin enough, in order to have them go through the holes and underneath the heatsink.

The thing is, that the Compaq V3 is the 3500 model, disguised as a 3000 model.
Phil's card are a Compaq V3-3500 (as so is mine), and they run even more hot than a 3000.
The problem is, that they have used the same heatsink as a standard 3000.

Phil's solution might make the card last longer, as such a big fan makes the card really cool.
The advantage of my solution, is that the fan takes lesser space. (More room for air circulation in the case)
I have tried both solutions, and mine makes the card slightly warm. Not hot at all.

Hi!
I usually don't invade other people's posts, but can anyone run pc-check 6.21 with voodoo3, and check video card at 1024x768 and see if everything goes ok? Mine stresses out at this resolution, but games work fine. And at that resolution win 98 in my pentium2 machine, run great!. Just PC-check doesn't run that card at those resolution.
Thanks!

------edit-------

My friend with a Voodoo3 also did the tests, exactly the same behaviour as mine. I guess, it's just normal. My card is fine. Thanks anyway.

What wide has those zip ties? I can't the 2.5 mm wide one pull through the small hole. Thanks!
What is the fan size? 4 or 5 cm?

Too long ago. I can not remember it anymore. Sorry.

Welcome to the forum!
I just tried and got a 1.5mm wide, 0.5mm thick zip tie through both empty holes on the heatsink of a regular V3 300 AGP with a bit of fiddling on the upper hole (there's a capacitor underneath).
Looking at the picture the fan is most likely 50mm which aligns well enough with the holes. 👍

Hello, thank you!
I've searched on ebay and I found this 1.5mm-wide type of zip tie, I think I will order it. Here in Hungary I couldn't find this type. I have also a regular V3 3000.
I tried with a 2.5mm tie, didn't go though. I cutted both sides with a knife in a part, this part went well into the hole.
I have a SilentiumPC 50 mm fan, I'm agreed with your opinion, that will be the ideal size.

I've bought a Voodoo Banshee Monster Fusion, it has a home made cooler modification (green chipset heat sink + another round-type VGA fan, I think the original was KO). I decided to replace it with this item:

The 55 mm distance between the holes will be good? I haven't got the card yet (maybe tomorrow).

You're welcome! 😀
I think even though the Diamond Banshee has its cooler glued on there are mounting holes for a cooler on the pcb but they're exactly diagonally across. The heatsink you linked probably won't fit those holes. 🙁 I don't know how far they're apart, sorry.

I don't how is removed from the chip, we'll se tomorrow. Yeah you are right, the screws are at different places. I will check it and buy another type of heatsink.

Worth it to buy for V3 3000's memory cells self-adhesive heatsinks? They are cheap.

che heatsink is glued, if you are no a pro , i would stay away from doing it since you can break the card

The memory chips don't usually need heatsinks, especially if you have a fan on the card.
But if you just like modding the card it won't hurt either. Just make sure to glue them on well so they don't fall off with time. 😉

Thanks for the answer, I will skip the memory heatsinks. Fan is mounted on the card since yesterday.

BLockOUT: I don't know who and how removed the heat sink, we'll see Monday when the Banshee arrives.

A cheap DeepCool V40, and 2-pin to 3-pin adapter from AliExpress:

The cooler has 55 mm between mounting clips. And Voodoo pcb has mounting holes with little less than 57 mm between them.
A needle file and a couple minutes of work fix the issue:

Of course, a full solution includes a fan speed controller to bring the noice down.
Basically, I think any cheap cooler with 55 mm mounting may work. But it should have a circular form, not square.
