MSI Twin Frozr II GTX470, one fan has died and the other is starting to grind. I replaced one of the fans with an old fan off of a CPU cooler; it's extremely strong but also very loud (92mm) I've just bought a couple of BeQuiet Silent Wings Pure (80mm) and they are useless. They have the highest CFM and static pressure of all the 80mm ones I looked at on ebuyer, dabs, scan, specialtech, candccentral, watercoolinguk and 100% positive ebayers but yea, I'm gonna need a couple of fans that actually move some air. Seriously, they spin so slow you can see the logo in the center still. I'm guessing 80mm isn't going to cut it. Feel p*ssed that I just wasted over £15 on these fans. So I'm looking for 92mm fan recommendations that are affordable and available from the sites above. If there's anything that performs as well as a Delta, but quieter, that would be good Has to be able to cool a hot graphics card. Thanks peeps.
