Fan Replacement for Geforce 3

[blackrain]

I am hoping this is the right place for this post (e.g., cooling).

I originally posted here:

But its archived and I don't see a reply option. This is a followup.

Anyway, i'de like to replace the fan but i'm not sure about how to do it. Someone else suggested a 40x10mm fan, but I am not sure how to go about doing the replacement.

Here's some new pictures of the fan on my card. There are two black mounting pins on the sides of the heatsink that go through holes in the card.

Any help would be greatly appreciated

My old GeForce 3 TI 200 (Which I still have) would take most aftermarket coolers.

My experiance. In my first build a FX5200 was used. The fan never gave-up but i did.

It was a little screaming weed-eater of a fan. It would run fanless but get hot.

I gutted the stock fan out and did a nice job of using super-glue to mount a three wire
RPM sensing 40mm fan to the stock housing. Since the PCI slot next to it was unused
this prsented no problem.

A good 40mm fan can be had for $2.50-$4.00

My Experiance with the FX5200 I could't get rid of it fast enough. It was a 64 bit data path.
Next to my old GeForce 3 TI200 it was a slug. I don't even remember if it had a fan on it.

Someone else also mentioned using screws to mount the 40mm fan, which is confusing as hell...i'm currently trying to get a better understanding of that through pm's. I don't think I want to use super glue in case I ever have to replace the fan again (which is always possible).

Since I found the original fan replacement for my geforce 3 (I have to buy two of them since there is a minumum $10 purchase), I might just do that instead. The 40mm fan solution seems like to much trouble to save a few dollars. I am willing to spend at least $10 to get this taken care of.

But i'll probably hold off for a few days and see if anyone else has another solution for using a 40mm fan.

If remember correctly the cooler that is on my GF3 is a chipset cooler that I had to elongate the holes with a round file and swap the plug also.

That sound like the best solution all round.

By the way, I found the exact part replacement for my fan today here:

Unfortunately, there's a $10 minimum order, but I can live with that.

It looks like it comes with the heatsink. To get around changing the heatsink and having to do the whole artic silver thing, can I just swap out the new fan from the new assembly and the old fan on my assembly. Would it be difficult to pry out the fan from the heatsink? More importantly, will I need to do anything else except stick the new fan in the empty space in the heatsink? I wonder if the new fan will just snugly fit into the heatsink

Don't use super-glue, use four tiny dots of silcone. let it set over night, then reinstall the
card. The fan will pop-off real easy with a firm twist. A quality 40mm fan will last
a very long time and be much queiter. Four tiny dots of Shoo-Goo works also. ;-)


Yes marvw, it was quite a jump from the FX5200 to a 6800 :-D

I think I might give that a try galvanized. I am assuming that silicone will leave residue if I remove the fan later. Is that easy to clean? I hope I still have silicone left from my previous project. I am also assuming that the silicone won't interfere any way in the dissipation of heat (I mean....there won't be any interference due to the silicone being between the fan and the heat sink)

 

[GalvanizedYankee]

blackrain, is this a parody of the OEM ram thread over at General Hardware?? If it is
your doing a good job of it. (hats off)

Abrate the surface of the fan at the four corners where it contacts the old fan housing.
Clean the housing where the silcone dots will be placed with alcohol, to remove any oils,
then install. Let it set over night inorder to set-up, then install.

I bookmarked that salvage site, i'll look it over later. Check out allelectronics.com

If I came across that way, I certainly didn't mean to. Just trying to figure out what is easiest and most successful thing to do as I don't want to have overheating problems later. And video card overheating is not a myth. I wouldn't be in this mess if the manufacturers actually cared about the products they were selling....the fan on this card was ridiculous.

By the way, I think my silicone cleaning question is legitimate because I thought silicone is resistant to most solvents.

I found this article interesting:

I am assuming that I don't need any heatsink compound as described in that article.

Looking at you pictures of your old fan, If the replacment is the same you should be able to snap them out of the old heatsink and snap them back in to yours. If they are the same. The one that came off my GF3 is screwed on to the heatsink. And my heat sink is a little bigger.

 

[blackrain]

This is the exact model number and looks exactly the same as the one I currently have (the label on the front is exactly the same)...I was shocked to find this....in stock

But it was such a piece of crap that I don;t know if I want to get the exact same one.

But it looks like you are right....the fan assembly is really trapped in the heat sink from this picture....I was wondering how to safely pry out the old fan assembly out of my current heatsink and pry the fan out of the new assembly to stick in my old heatsink
