Hi!

I was thinking about clocking my Geforce3 TI 200 just a bit and decided that I would like to install a fan for protection.
But my GPU only has a passive cooling heatsink.
I doesnt say Geforce3 TI 200 anywhere on the card and the card is called:
MS-8851 VER:130 - IBM FRU 49P0279

This card doesnt have a fan header but it got the throuholes for it but it's also missing some components. (two transistors/mosfets and some capacitors and resistors).
I got two pictures, one of the front and one of the back with the traces marked.
I have followed the traces with my multimeter and I think that these just are the required parts.

So what I need some help with is if someone has a Geforce3 TI 200 with the fan header that can check the parts for me, or if someone got a educated guess whats needed. 😀

I looked at pictures online but the resistors is hard to see but some pictures got 2222 transistors installed.
What do you guys think?

The parts needed:
R202
R200
C235
Q200 (looked like a 2222 on a picture I found)
D200 (some pictures I found omitted these parts)
L202 (some pictures I found omitted these parts)

Thanks in advance!

"Protection" from what? Ze Germans?

MS-8851 was a common OEM card, made by premium mainstream shop Microstar International for DELL and, apparantly, big blue.
If it was shipped without a fan, then probably it was intended for use without a fan by the big Ju-Ju up the mountain.

Wanna play it extra save that regular use will not result in catastrophic instability of certain games, lave the next door bracket open.
There, I fixed it.

Cheers!

Well, ofc it was made to be used without a fan but adding one is mostly for fun and knowing that the electronics is kept cool and safe while doing some OC.
As for leaving the next slot open, cant do, all slots already take up. 😉

Hmm well if you have the Dell version it has no heatsinks on the Vram unlike all retail Ti-200's so you will be very limited in OC even if you fit a fan on the GPU heatsink.
Most of the Ti-200 OC involves bumping the GPU by say 25Mhz but also bumping the memory by 50mhz (key is bump ram 2x the cpu bump).
This page shows how going from stock 175mhz gpu / 400Mhz ram to other OC speeds: https://www.anandtech.com/show/873/3
I like that they use the Gainward GeForce3 Ti 200 Powerpack (Ti/450 Red https://www.anandtech.com/show/873/9 ) as I have two of them ;p
Once you get the GPU fan header figured out Get some heat sinks for the Vram and you should do OK

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor.

OK, now, more fun, that's an entirely different story. Just don't kid yourself!
Then attach any random fan and hook it up to the next best molex connector. Yellow cable is 12 V.

For, while I do have my little brother's old GF3 Ti-200 somewhere on the heap and it was indeed some ASUS with a fan, I don't think you'll need the reference here, even if you insist on using the fan header on the card itself.
Are you sure the solder spots are without juice as it is? What were these components supposed to do? Fan speed control? Don't think that was even remotely a thing with the Gf3.
But, probably some Gf3 specialist here will correct me.

In any case, if you are to keep your PCI card overkill, then the fan's power supply may not be your main problem. are you sure there's room in the slot for the heatsink plus a normal 50 mm fan? For, all the gf3s had an "inline" fan or a fan in a really simple "flat" heatsink.
So, by all means, tinker away, just keep in mind that since you're the owner of a SLI voodoo set and loaded anyway, you might as well go ahead and buy a Gf3 with a fan 😉

Also, on the open/serrated bracket approach: Keep the Voodoos and the audigy, get a 100 Mbps ISA NIC!

I agree ! Those fans spun about 1000 rpm and were constant iirc better to get a 128Mb one with a fan and vram heatsinks 😀

I think you're looking for this:

I would try without the parts marked "no stuff" at first (as you mentioned, they are missing on some cards). If you don't have continuity across L202 pads I think you can safely short them.
And, since it's been mentioned, fan control was a thing on GF3 - at least for the MS-8850 model 😁

wish I could help, I don't think it's worth the trouble. I would probably just run a 3 pin fan off a controller so I can control the fan speed myself. If youre looking for a quiet PC that is. You won't have any fan control speed with it wired to the card.

Thanks for the input guys!
I have now added some heatsinks to the vram and added components according to quicknick's schematic and it worked great!
Now the fan works and I can try some OC. 😀

And yes ofc I could just use a fan header splitter or molex adapter but like I said, I think its fun to add a missing/omitted function to a otherwise basic card.
And I already got plento of components laying around.

A 128MB card ready with heatsinks and fan would be nice to have but that I dont have, what I do have is the required components, heatsinks and fans thou. :p
A 128MB card will be for the future when I have sold off some of my other cards. 😀

Congratulations!

And, excuse me for poopooing your plans a bit at first.
Of course, it can be much more fun to do things the proper way, beyond mere necessity. It's just that so may people here seem to be totally over concerned about hardware requirements, spend lots of time and money and fail to tell fun from necessity. So, me being German, I had to point that out. 😉

Btw, still wondering what heatsink and fan you used that won't bother the voodoo next door. Treat us to a picture, please!

No problem. I just like tinkering. 🤣

For heatsinks I had some small obes I put on the vram with thermal adhesive pads. For the main chip I still used the stock heatsink.
For fan I took one from an dead gpu and screwed it to the old heatsink.

The geforce3 ti 200 and voodoo2s have one slot inbetween and there I have a low profile network card. 😀

The computer is already screw back together and connected, but Ill try to make time to open it up and take a picture for you as soon as I can!
Im a father of two kids so time is kinda limited. 🤣

The heatsink Im not that happy with so they might get changed in the future to some that fits better on the chips.

And for my next project, adding front usb ports.
Also a kinda dump project.
Technically in my setup I got one pci slot open between the isa slots and pci slots. But there is no opening in the backplate because the isa cards/pci cards are the otherway around.
So..., i have a 5port usb 2.0 card that works on winme and the plan is to desolder all ports and rout them to a header, trimm the pcb and then connect it all to a 3D printed frontpanel.
This front panel will also have audiojacks coming from the Audigys header.
And yes, the motherboard has two usb ports that works and yes I will probably not use the front ports that much but to me this is a fun dumb project.

Sorry for being the buzzkill once more, but in the interest of more time for the kids:
Many simple USB-sound front panels around retail for the 3.5 or 5.25. And, if two connectors would be enough, there are actually PCI USB 2.0 cards available that have the usual internal 2x5 header to attach any generic USB bracket or front panel. So, if you could live with that, just remove the backplate and maybe the sockets.
But obviously, go with what you have and know to work - soldering on four cables per port shouldn't be rocket science.
With sound, there are standards for that, most likely AC-97. If, by any chance, Creative Labs should have bothered to adhere to any of those. 😉

Haha. No problem.
I got 3 sound cards in my system, the two isa ones are connected to the audigy so I only need the audigy ports in the front for headphobes really.
And its nice to get some use out of the 3D printer.

And USB, i looked around for usb 2.0 cards with internal header and found some but then I would still be needing to desolder the back ports (didnt find anyone with only inter al connector) and if I would desolder ports anyway then I could just as well just use the card and loose connectors I have.

So it comes down to, its fun again and that I already got stuff at home so I dont need to buy anything new. 😀

Thanks for the input thou, I will look around for the front panels. Maybe I can come by one for cheap somewhere in the future.

most of the geforce3 ( i got a couple) share the same design. in your picture the fan connector is missing, the position is J200 on your picture. test with a multimeter if you get 12v on one of those 2 points, and the other one is ground. it runs to a 12v fan 0.07amps that is about 50mm big

to be honest, my personal opinion about gpu cooling from that era is just a mess, that they did crappy heatsinks in order to make the card pretty.
You are way better if you take out one of those CPU fans from an AMD cooler, and just plug the 3pin connector to the motherboard and place the fan on top of the geforce3
way more air flowing with force.

my personal opinion is because the leaf blower geforce fx, and also geforce 4200 series from msi, i opened the heatsink and when opening it, the small metal fins where air is supposed to go to, were glued with UHU to the copper base, incredible.
