Supergluing S7 Hs to Voodoo 3 2000, is this good?

[wtp]

i'm planning to take off the stock HS, and put a s7.. but is superglue good, and can i use scotch tape. I'm planning to glue the corners, and add thermal paste in the middle. Is this good, what are the risks of taking off the HS of this v3 2k?

Stay away from superglue inside computers...just trust me.

The vapor will destroy any electrical contact point exposed to it ( like memory contacts or cpu contacts...)

I have a V3 3000, I'm not sure how similar the two cards are in terms of cooling and methods of attaching the heatsink.

On the 3000, there are two metal pins that go right through the board. These are re-usable, so there's no need for glue. I took the heatsink off because there was a cr@ppy thermal pad and I wanted to use proper thermal paste. The pad was also adhesive and made the heatsink a pig to remove - I thought I was going to rip the chip off the board at one point!!!!

Once that was done, I added a CPU fan to the stock heatsink (BTW - if you get ANY paste on the interconnects around the outside of the chip, the board won't run - it is extremely sensitive to this). I only epoxied the fan to the heatsink and it works gr8!!! There was such a difference in the HS temperature, that there was no need to upgrade the HS!!

If you want to test whether just adding a fan will make a difference, run the system up and let the V3 get hot, then just hold a running fan flush up to the stock HS and see what happens - I found that in a very short time, the HS was practically COLD. If this is the case with your card, you can keep the stock cooling and save yourself the hassle - just add a fan!

good luck just getting the stock heat sink off that thing I've had 2 or 3 people tell me that they just pop off well not mine tryed it cold tryed it really cold tryed it room temp tryed it hot and tryed it really hot that, @#$%*& thing will just not come off with out a hack saw lol or crowbar http://sysopt.earthweb.com/forum/frown.gif

best bet is adding a fan to the back side and one to the heatsink on it, bend the fins in a little at the corners and the screws will catch no problem, for the back side 3 or 4 mobo risers with the tabs cut off and some frag tap work really good sick the part that goes through mobo into the screw holes of the fan cut off the bottom part that locks into mounting plate for the mobo, and stick the frag tape there then just press it to the card where ya want it http://sysopt.earthweb.com/forum/smile.gif

I found the HS seemed to come off easier it I twisted it with respect to the card, rather than pulling it. It was still an absolute b!tch to remove, tho!

the 3000's are not glued on like the 2000's are, mine looks like they JB welded it on http://sysopt.earthweb.com/forum/smile.gif

The b@$t@rd$!!

[scotter]

thats what I said you should see the **** they did the heat sink is at least 1mm off the core they used so much goop http://sysopt.earthweb.com/forum/frown.gif

[wtp]

hell yah, the whole HS is raised up. http://sysopt.earthweb.com/forum/frown.gif

wtp,

If you want an easier time removing the H/S you might want to try puttin the card in a 250F oven for a few minutes to get the goop that 3dfx used pliable. It is a thermoset material. Then you can use oven mitts (and you'll look real funny!!) to hold the card and twist the offending H/S off the IC.

BBA is most correct. Cyanoacrylates (super glues) leave a reaction residue everywhere. Don't go there. If you must crazy glue something, join it outside of the case and then let the glue cure for 24 hours OUTSIDE THE CASE. Patience is a virtue in this case!!

If you really want to make a pissa modification to the board, you can EPOXY two threaded plastic studs to the Voodoo board (hacksawed to the appropriate height) and then put the heatsink thermal grease combo onto the chip and then use a wire or aluminum strap to hold the H/S in place. I use this in a couple of my system now for several different types of IC's that I wanted to provide better cooling for.

Just be careful not to epoxy the studs on top of exposed PCB traces or components and everything should be OKAY!

Good luck and have fun...

Interesting reading this, AFTER super-gluing my graphics cards. If I'd read this first I wouldn't have dared try it:

"Last night I tried to run my Ge-Force at max over-clock (both sliders set to max). It wouldn't have it, 3D-Marks went to a black screen as soon as the helicopter test started and the PC needed to be re-booted.
Tonight I decided to give it, and the TNT-Ultra in my other PC, some extra cooling.
So, the hairy procedure. Using a screwdriver I levered off the heatsinks, putting a little wad of tissue between the blade and circuit board so as not to damage it. With a bit of pressure the heatsink sprang off, leaving behind a load of dried crud on the chip. I gently scraped that off with a sharp knife.
Then I applied a good blob of superglue to the chip and stuck on a big CPU heatsink. After about ten minutes the glue had set solid. On went the fan and back into the case went the whole assembly, with me praying I hadn't screwed it up (I did the TNT first, just to be sure).

I then set both OC sliders to max and ran the 3D-Marks prog. I got 150 extra marks out of the TNT and 300 from the Ge-Force, and the heatsinks weren't even tepid."

NB: I stuck the cards back in the PC's about ten minutes after the assemblies were set. I could smell the fumes in the room (smoking gave me a head-ache, lol) but there were no probs at all.

The glue I used wasn't the kind that sets on contact. You can move the heatsink around for a couple of minutes to get a good seat, then leave it for about ten minutes. After that it's solid.

Was I just lucky or did I find some really good glue by accident?

Im not sure how good these things are or the company but have you considerd these? http://www.tennmax.com/voodoo3/stealth_v3.htm Seems like it could work .....or just find there instructions for a guide to your own project? Just a thought Mykex

I posted on this a while back--look in Video Cards. Should be a post about OCCing and super--cooling a V3 2K.
