I will put more photos , when I open the pc again this friday.

If its single slot, cools the GPU and the memory well, and reasonably silent then it looks to be a good option Marmes. It looks to be pretty thin but fairly large surface area.

I managed to get a bit more testing today on mine when a cheap mobo from ebay showed up in the mail. Just for a heads up, the back of my GPU is reading about 3-4 degrees hotter than the front. I may go ahead and stick a little 40mm square heatsink on there and be done with it. That way, active cooling from the side panel fan will help that area a wee bit more. I'll look into that when I build a rig with it in the next few weeks or couple of months.

Apologies for necroing a very old thread, but I hope this is useful for others with a PCI Voodoo3 3000 like mine. My PCI card didn't have heatsink mounting holes so I took a different approach using zipties to attach a 90mm slim fan - this setup only consumes 1 additional adjacent slot and conveniently also blows air directly over the memory chips. I ran one of the zipties under the heatsink and the other through the holes in the extreme corners of the card (no idea what these holes are intended to be used for):

I find it's a lot easier to leave the cards as they are and just add good case cooling. Installing a single 2000rpm 80mm intake fan to the front fan slot of my super 7 build's case reduced the voodoo 3's temp from 73C (after 35 mins of quake 2 timedemo loop) to 58C measured with an infrared thermometer. To achieve this I also blocked off all unused expansion card slots apart from the one directly under the video card, and fabricated a plastic deflector in the shape of a slope that deflect the air from the fan directly to the video card. That way most of the air is forced past the video card's radiator before leaving the case. Later I added another 80mm 1300rpm exhaust fan at the back of the case using the rear fan mounting poit, that brought the temp down another 3 degrees celsius - and I'm very happy with the results. I also think two 80mm fans are a bit quieter then any 40 or 60mm fan I could have stuck to the card itself.

Couldn't you risk this "lifting off" the heatsink, when it gets hot?

This was pretty easy... I already had the fan and this took less than 5 minutes and lowered temps much further than any of my indirect case fans.

I doubt it... the ziptie attached to the card itself is very loose so that the fan isn't pulling on the heatsink. The heatsink is also basically glued/epoxied to the card. Phil did something similar in his video (but the heatsink in his case was fastened to the board):

I have a GeForce 4200 Ti with a Zalman ZF700 cooler that indirectly cools the Voodoo 3 underneath, it works well in conjunction with a 140mm side fan:

I have a GeForce 4200 Ti with a Zalman ZF700 cooler that indirectly cools the Voodoo 3 underneath, it works well in conjunction with a 140mm side fan:

A side fan would be perfect, but the case my Voodoo3 is currently in unfortunately doesn't have a spot for a side fan. I've been attempting to locate a small Full ATX case for my Socket 7 build that accepts a side case fan unsuccessfully.

I used a CM 361 for my Pentium 4 build that was the perfect size and had a side slim case fan blowing over a pair of Voodoo2 cards: Re: Help spec my P4 Win98 Retro Rig

I just put a little 40mm fan on my PCI Voodoo 3 2000.

The other fans and the bearings in the hard drive drown out any noise from it. It seems to keep it adequately cooled and it fits the tiny heatsink well.

My PCI card is from Elpina according the video BIOS, according to the eBay seller I bought it from it came from a arcade cabinet. It has a tiny little heatsink.

My AGP 3000 model I've done a Phil's fan mod it and again it works well enough.

I don't look at these cards so I don't much care about the appearance. But there are some impressive looking mods on this thread to be sure.

A solution may be to use an old 56k modem card or something similar that is no longer in use and has good dimensions.
A sanding to the components and all the copper tracks and a cpu fan, the narrowest you can find.
This way you poke the fan into a pci slot.
It works very well for me with an rpm regulator.

Wouldn't it be easier to just buy a PCI fan bracket?

You can fit two 90 mm fans into that for quiet and efficient cooling.

teclillass,

While I admire your ingenuity and craftsmanship, there are several cheap solutions available from eBay that are much easier to install:

I was unaware that they had pci with a fan. Sounds great to me, much better.
I like this better than hanging a fan on the card.

Sorry, I was unaware that it already existed. I did this quite a long time ago.
And I'm glad it's available now without getting dirty.

I really like your design. I came up with something similar for one of my Voodoo 3 cards, but your idea is much more robust and securely attached. I took a slot cover, straightened it out, attached a fan to it, then bent it into position to blow directly on the V3 heatsink. It's similar to how I did this Voodoo 1, but angled to blow directly onto the V3 heatsink like you did with your unused modem:

Tyan P200 MMX Voodoo 1

I have seen his invention, it was something very common at that time. You had to take advantage of all the megahertz possible.
I like the blocks you have on the card. A good pc. Thanks for showing it.

There are 2 possible problems on my card.
-The space of a pci is not always possible
-The screws are metal and should not touch any card.

having solutions as you have said, it is not worth doing DIY.
Anyway feel free to pick up any ideas that may help you.
