vga cooler for 7800GS

I will be receiving a BFG 7800GS from my friend for $35 next month.
The fan makes a lot of noise and I'm sure it will fail at any moment;
not wanting to pass up a $35 7800GS, I've decided I'm going to replace
the fan with something a bit quieter. Finding the appropriate device
has been somewhat of a problem, I keep coming across VGA coolers with
this in the description; The product cannot be installed on Matrox VGA
cards, NVIDIA PCX 5 , NVIDIA Geforce 7800GS/6600 Series. Any of you
have insight as to what product I should be looking for? Thanks!
