I need to attach a heatsink to my v3 but i dont really wanna use epoxy but if frag tape is really that horrible i will use epoxy. Whatdo u ppl think?..
How horrible is frag tape vs Epoxy for my video card

Thermal tape does really suck its almost like a heat barrier if you compare it to thermal epoxy. With a V3 why not try drilling some holes in the heatsink to line up with the pre-made holes on the v3 already. Screwing it in someway, or even use some tie straps, then you can use something even better then epoxy such as some silver paste. Heard some good paste is around that beats the popular curcit works silver greese but its non conductive forgot the name.
Heres a pic of pretty large heatsink on my v3, i used avvid thermal epoxy which is one of the best thermal epoxys but im gonna redo it over again using tie straps and that non conductive silver greese.

That is truly a MONSTER heatsink on that card. What is the smaller heatsink for? Is that a RAM chip? (I can't remember the layout offhand.)
What I did is smeared thermal paste all over the chip and then put a drop of glue in each of the four corners to attach the heatsink (with a fan glue to that). Made a world of difference in overclockability. I dunno if it would be strong enough with a heatsink that big though, but you could augment it with zip ties. (Actually I had put ramsinks on too. I doubt that did anything, but it only cost me 2 bux.) When my non-conductive Arctic Silver grease comes I'll redo it, with a 50 mm heatsink/fan. I was also thinking of putting something on the back, but I don't think it would do much, and the only real safe way of doing if is using frag tape. Even though the heatsink is anodized and the grease in non-conductive, I'm afraid of shorting out my V3.

I think that small heatsink sits on the DAC or maybe it was the bios, but i remember that chip got kinda warm so i slapped it on there with some extra epoxy i had.
Ever touch the back of the chip of the v3 shiet is damn hot, actully cause of that huge heatsink, the stock HS on that sits on the back gets hotter then the big on that sits directly on the chip. I used 3M frag tape on the back, to hard to get full insulation with paste.

Just use superglue.
A good heatsink with lots of surface area together with good air flow through the fins more than makes up for the temperature drop across the superglue.
Don't get me wrong, thermal grease helps and I'm certain to have some on my CPU, but when you go from a dinky graphics card heatsink that came on the card to a big huge aftermarket heatsink, you'll be fine.
Also more important than the glue or grease is the surface contact. Air sucks.
That's just my take.
Any other superglue fans out there, and before anyone asks, I did this on my TNT2 but the CLAP2 hasn't been oced yet.

Superglue is not a good thermal conductor. Regular epoxy is a poor conductor, but thermal epoxy is not bad.

Like I said, superglue AND thermal paste. Smear on a very thin layer of paste on the chip and then remove about a 2 mm rim around the edges near the corners. Dab a little at each corner (+/- along the edges of the chip depending on the size of the heatsink), apply the heatsink, and push down HARD, with a little wiggling to spread the paste (but not too much or else you'll spread the paste into the areas where the glue is). Hold for a minute.
Voila! Better thermal conductivity than thermal epoxy and of course, superglue alone. Then superglue a fan to that heatsink.

Sounds interesting. But, don't you want to have the thermal compound under constant (light) pressure to keep air gaps from developing.
Just a thought, maybe I just need to try it on something.

Side note, I think that RAM heatsinks aren't worth anything. Comments are welcome. Since when did the RAM get hot.
And lastly, when do you all think that video cards with adjustable voltage will come out.

No way in hell super glue is gonna hold my heatsink on, it almost wieghs a pound. If it did hold probably one little bump falls down on the compents below it and probably shorting something. Super glue drys like plastic which is really poor conductor of heat, and i think i remember back from my airplane modeling days which you peice 1000's of pieces with mostly super glue, when it drys it expands a little, so it could be possible the heatsink could be hovering slightly, but probably not seen by the naked eye.
Probably does look cool. As for the superglue, it ain't perfect, but it will hold. Try the superglue gel made by Loctite.
As for temperature drop across the superglue, remember, when you replace a simple little no-fan sink with something near the size of an alpha that has a fan, you can lose several degrees in the temperature of the heatsink but still dissipate much more heat so long as the increase in surface area and convection is sufficent to make up for the temperature loss.
Of course, if you have something better available, use it.
Cheers,

Well, some people use the superglue/thermal paste along with zip ties. That seems to work for the ultra big heatsinks.
If you don't have thermal epoxy, some people on this site have recommended using JB Weld. I have never used it, but they say it works well enough because it does have some thermal conductivity (but not electrical conductivity). One guy even mixes a bit of thermal paste in with the JB Weld.
By the way, I used the same method (glue/paste) for my RAM but I'm convinced it does absolutely nothing. But for $2 in heatsinks I figured what the hell.

Oh yeah, while cards with adjustable voltage are unavailable, you can still set the voltage.
The spec for the AGP slot (and memory) is 3.3 V. But many boards now come with it set at 3.5 V. I don't claim to know why but it would seem that change came with the popularity of the faster 3D accelerators. In fact, while my Asus is already at 3.5 V, it has a VIO jumper test setting for 3.7 V. Does it make a difference? Yes. When I installed my new CPU and overclocked it to 100 FSB my system refused to boot until I upped the VIO to 3.7 V. It turns out I had a very crappy piece SDRAM, and swapping that stick out allowed me to go back to 3.5 V.
I dunno if that's gonna help my video overclocking project. I'm getting better paste and a better heatsink/fan, but if that doesn't help stabilize my V3 2000 at 183 MHz then I'll try upping the VIO.

I've said it before: Use ordinary silicone rubber sealant -- all over the two surfaces. No thermal paste with this.
well i zip tied my large heatsink on after i sanded it. it only gets hot without a fan. it only gets warm with a fan on it. i put the stock v3 2000 heatsink on the back and it gets pretty hot.im going to use frag tape for the ram chips though.
