VF-700CU vs Stock 7800GTX 512 & X1800XT Heatsinks?

Hey all, this is really close to a million other posts, but cut me some slack pls

Anyways, I love the Zalman VF series...I've used a 700-AlCu on my 9800Pro-->XT for what seems years now, and I love the quietness and undervoltability...I'm just wondering it's quite an aged product, how does its thermal dissipation abilities hold up against these huge, hefty heatsinks? And if it can indeed run, can I overclock the card any? Or run the heatsink at anything other than full blast?

Surely it will do a worse job than the monster GTX 512 cooler. I'm not sure about X1800 XT, but I'd forget about overclocking.

To change subjects for a moment...

Does anyone have some first hand experience with the GTX 512 boards to give a feel for how loud they are?

my thinking also.
Some of 7800GTX (XFX??) cooler using 90mm fan, compare to VF700 which use 70mm fan.

its 92mm, not 90mm.

and the vf700 uses an 80mm fan, not a 70mm fan

and personally, i have a hard time believing ANY stock cooler with a fan is "quiet". i think its much more probable that the people that are claiming its noise as being so low, are OC'ers that are used to 40/50+dbA systems.

Replace the fan then

I'm sure that with such a good (stock) cooler a Nexus fan could cope quite well. Or am I wrong?

I guess that would work. You'd have to use ATITool or similar tool to set up different fan speed maps according to temperatures, but I guess it could be done. Any brave soul willing to test the hypothesis be my guest

Or on a more simpler approach, just use RivaTuner to refuce fan speed
