Small fans on graphics card are notoriously noisy. Modern graphics cards
generate a lot of heat, so need alot of cooling. The problem with the
factory fitted fans is that they are naturally quite small (to fit on the
board)... and.. .the problem with small fans is that in order to pump enough
air through the heatsink, they need to spin very fast. A fan of double the
size would need to spin at much less than half the speed to pump through the
same amount of air.
You could make sure that the 4 screws at the corners of the fan are tightly
fixed (not vibrating). Someone else already suggested this, but make sure
the fan is as clean as you can get it. This will not directly reduce noise,
but if it is clean it will cool more effeciently, therefore not need to spin
at high speed as much. You can probably take the fan off for cleaning -
clean in all the parts of the heatsink as well.
Of course, if the air temperature inside the case is high, then no amount of
cooling on the GFX card will help because you are trying to cool it with hot
air. You might consider an exhaust fan on your computer if there is not one.
These are pretty cheap and if you get a slow spinning one, it will reduce
the case temperature and hardly add any noise.
Remember with fans - the bigger they are, the slower they need to spin and
the quieter they operate.
If you are annoyed by the noise, you can get replacement fans that make much
less noise, or even some silent ones. If you go to google and search for
"silent graphics card cooler", you will see there a number of options. You
can replace the fan on the processor, chipset, case, PSU - anything! Have a
look at www.quietpc.co.uk for some more ideas. They are not the cheapest,
but they have some interesting stuff. (Not sure about GFX card, but the have
some case noise reducing stuff).
