overclocking a voodoo3 2000

[toph99]

i am planning on oc-ing my voodoo3 2000 pci, and i have done some things to cool it more, as most of you know it gets VERY hot. enough to burn you... believe me, i know, lol. there is only a small heatsink on it, so i bought a 486 fan from radio shack, and screwed it on with some self tapping screws. i have no idea what the CFM for this fan is, but it works well. i places it so the air was blowing down onto the heatsink. i figured this worked better with a low cfm fan than trying to draw air up through it, am i correct? and i just added an 80mm intake fan over the card. the heatsink fan cooled the heatsink from searing hot to just quite warm, as well as cools the memory somewhat, though it never got more than slightly warm. there is a little chip on the top corner(if u have one of these, u know what i'm talking about) with a funny looking metal incasing around it, i am assuming a form of heatsink. this still gets very hot, because it is too far away from the heatsink to benifit from the fan. i positioned the 80mm fan more or less over it, so it should be getting cooled, though i have no way of knowing because it is hard to take off the side of my case with the fan there. now my question is, even though the card is still very warm, but not burn-your-finger hot, would overclocking it like this have minimal chance of me ruining the card? it was running extremely hot before i put any kind of active cooling, andthat is how 3dfx shipped it, so with all this extra, should it be ok? thanx =)

The fan should be your 2nd step. First, take off that heastsink that came on the card, and make sure to put some Artic Silver or some sort of thermal interface (silicon compound will do the job too). Then put the heatsink back on. The fan is a good idea; I also used one on my v3 3000. Then, I also but a heatsink on the back of the card. As you said, these babies get VERY HOT! Your V3 2000 should have no problem going up to 166 (from 143). Run it for a day to see if it ever crash. Then go up in increments of 4-5 until you hit your max/sweet stable spot (175?). Some V3 2000 can go up to 183 but that's a serious risk on the memory chips. My V3 3000 can do 190 no problem; I needed that heatsink on the back of the card when I went up to 195 which ran stable, but I am just running it at 190 now. Good luck!

I glued a standard S370 HSF on to my voodoo using metal epoxy and it works great. Running at 185 totally stable.
