What about using heatsinks intended mainly for use on modern motherboards ? I am sure there is a way. A zalman we should find :)

Software way... I came across with some fan undervolting ideas but i am really not sure if it could be done to the videocard fans.

fan undervolting:

Thank you btw :)
Clean it with compressed air. ( may help )
Take it out and apply some turbine oil in the middle where the bearings are ( also withstands high temps )
Last option would be to replace it

The video card is one day old and the fan seems to be made by ATI.

Those fans are noisy indeed. Read this article :

If the sound is extremely abnormal even for a noisy fan then you may rma the card.

You can buy a quiter fan and replace the existing fan on the Video Card. search for "Zalman" fans compatible with your video card. Here is a fanless version of your video card if I am not mistaken.

Best of luck ~ Mechy

At new egg below the page:
Cooler      Heatsink and Fan :)

A fan mate would be a hardware solution, but i'd prefer a soft to lower the ati freq and cool it so.

Cool article Purple_Sky.

I use 2 fans at 5v for the power supply, it's a good idea about using 7v when needed.
For the video card a thermistor controlled fan would be the safe solution.
I needed to replace the video card :( and the new one Nvidia has a really silent fan.
