If your lucky enough to own the first GPU graphics card, please read. In honor of the 20th(ish) anniversary of the Geforce256 DDR I've decided to help preserve it's legacy and give owners a chance to extend the life of this card. As we all know heat is the enemy when it comes to computer chips. That means that every component has a life. If your cooling fails and your unaware of it, this will drastically reduce the chips life span. I have acquired a Geforce256 DDR card and went through the process of replacing the GPU fan, which can be a daunting task. Specifically regarding the Creative Geforce256 DDR (CT6970), I was able to locate new OEM Adda AP4512MX-G90 fan's but unfortunately they only had wire leads and no 2-pin connector. So I did some research and located all the necessary parts and the crimper to complete the job. The end result is a factory new OEM fan for these cards. I have bought several of these Adda fans and terminated the wire with the proper 2-pin connector. If you would like to purchase a new fan please contact me. In future posts I will outline the parts and steps necessary to complete the job yourself.

For reference I have identified four major types of DC 12v fans for Geforce256 DDR:

Brand, Model,Card
----------------------
Adda, AP4512MX-G90, Creative
MEI, MOTHR-1024-C, Visiontek
Millennium, MOTHR-1024-C;MFAN-1024-D, OEM;Dell;Gateway;Visiontek
Nvidia branded, NV-1024-C, Visiontek

It is a nice project to help preserve the lifespan of the card. Having an option to get a new fan is always good news for me.
I had this problem of finding a AAVID fan for a 3dfx Voodoo 4 4500. With the help of the nice people of this forum I managed to find a link to a US seller on eBay. It was more expensive that I was hoping but in the end I'm glad I could find one.
As per the fan on the Creative Labs GeForce 256 DDR; that fan is also used in the SDR card (CT6940) and in the TNT2 Ultra (CT6810). With old fans you almost can expect them to make some noise or not run at all from the dust or other stuff that might got inside.
It is relatively easy to clean though. Just unscrew the four screws that attach it to the Heatsink and unplug the power connector. After that, on the back of the fan remove the little sticker, and you should see the "washer" (I think its called washer), it is this white little ring around the shaft of the fan with a cut across its diameter. With some persistence, a pair of small pliers or some small needle, it must be removed (make sure not to loose it!!, it often pops). After that, the fan blades with its shaft can go out from the rest of the fan. Clean everything with some cotton ear buds, even the hole where the shaft goes, use some twisted paper towel to do it. After that, apply some Lubricant into the hole (I use a Lubricant that came with my Electric Razor and it works just fine), insert the shaft in and out a couple of times and give a few spins after. Then reassemble everything like it was, while not forgetting to put back the Washer in place. The fan should work fine after that with no noise.
I have done this on many cards that the fan was making noise and after this it worked fine with a success rate of 70-80%. My latest success was an identical fan like the one you mentioned of a TNT2 cards.
On a side note, I want to mention the awful AAVID fans that come with the Matrox G400 MAX, almost guarantee they are noisy, and even cleaning them makes no difference.

You can get new heatsink fans here for five bucks

It's the one in the third photo down. Which also just happens to be a photo of my own Dell GeForce 256 ddr 64mb.

A good replacement HSF combo for our beloved GF SDR/DDR cards would be awesome.
Preferably something that uses the mounting holes and not having to be glued to the chip.

This one works just fine (and probably has 5x the cooling capacity of the original) but it looks ghastly:

And also blocks several expansion slots.
Sacrificing one PCI slot next to the AGP is usually just fine since they tend to share IRQ anyways.

Small world, thanks for chiming in and for use of the Geforce 256 photo. I had a hard time locating high resolution photos for my post. Great retro PC setup by the way, it looks like you go the extra mile in locating excellent condition or new parts for your rigs.

Thanks for letting us know about the other fan/card usages, good to know that these fans can be refurbished. It'd be great if you could upload some photo's the next time you complete a fan cleaning/lubrication.

There is a video on YouTube made some years ago and still IMO is one of the best explaining it. Here is a link to it:

As per the link posted above this, please don't try removing the heatsink from the card. It glued into it and is likely you will damage the board or the chip underneath.
Just unscrew the four screws and clean or replace the fan. Cannot be risked on a GF256 😀
