I just got an ATI X1950 Pro graphics card. I would like to replace the stock fan with a Zalman VF900. I have never done this before, so I'm looking for some guidance as to how you do this.

Zalman doesnt have it on the web site?
Mounting Instructions
It says for all ATI Radeon X series u use holes 1. Unless the mounts on the X1950 series is drastically different, the VF900 has 5 different possible mount combinations, that you couldnt go wrong.
I wasn't clear. I know how to attach the Zalman. What I don't know is how you take the stock fan off of the X1950 Pro.

oohhhh... lolol...
Flip the card on the back. You'll see 4 screws on springs and then 3+?? other screws.
(looking at the picture on newegg.com)
Unscrew all those screws and the stock should come right off. Dont use too much force, because if its not coming off easily it means ur missing 1 screw. Also u need to unplug the fan from the card.
After that u need to wipe the memory and the Core off clean with 90% rubbing alcohol. I say 90% because it drys up really fast. But make sure your core is clean. It should be a shiny black color.
Reapply the thermal grease on the core evenly. Doesnt need to be perfect, but just enough so the top of the die is colored white, if you use the zalman, and silver if you use AS5.
Then mount. Your going to have to use maybe slots 3 or 4 and not 1 the 4 spring pins area to mount the VF900.
Hope this helps

The VF-900 is not a passive cooler, and it comes with 8 ram heatsinks. Does that deal with the concern about the VRM? Or is that something different?
I know what the VF-900 is and whether it is passive or not doesn't matter. The VRMs need some sort of heatsink on them and that is not provided by the VF-900.
You can probably use the RAM sinks on the VRMs since the RAM doesn't really need them but you might want to use some thermal adhesive since the contact area is so small on the VRMs.
Thanks for clarifying that. So, what the best thermal adhesive to use for the RAM sinks? and where do I get it?
I use Arctic Alumina Adhesive but I also mix it with regular thermal compound just to make it removable if it has to be. Just remember to peel off the thermal tape from the Zalman RAM sinks if thats what you plan to use.

Operandi is our HSF guro, salamander, meaning he's probably one of the most informed on air cooling. Listen to this guy, its highly recomended.
Also operandi, wheres the darn sticky??? i want to make a 100% passive system and your sticky is POOF out of the air.
Thanks for the kind words
. I'll try to finish up the thread this week; digging through all those links is time consuming and anti-fun, it also doesn't help that I'm lazy
.It's not really important what kind of compound you use (I think I used Céramique), any type should really do fine.
As for the proportions I believe I used 1 part thermal adhesive and two parts thermal compound. It holds much stronger then the tape Zalman uses but can still be broken free with a firm twist.
One more question - is it ok to plug the Zalman into the graphics card rather than use the FanMate 2?
Connecting the Zalman to your graphics card is OK (Gigabyte's higher-end cards actually come stock with Zalman HS/Fs) and brings the benefits of automatic fan control so you'll get better performance as well as lower noise.
The catch is the Zalman's connector won't fit your graphics card so you'll have to cut the ends off of both fans and swap them. This has been done many times and it's not difficult if you are at all familiar with a soldering iron and heatshrink tubing.
And yes I'm pretty sure Céramique is what I used on my CPU.
