My Gigabyte GTX 460 1gb OC version arrived today. You can instantly tell it's got a much more substantial heat-sink than the Palit card - it's much heavier and feels much more solid. Ironically the Gigabyte was around the same price as my Palit card.
The cooling solution looks better than all the other cards I've seen, the only one that gives it a run for the money is the MSI Cyclone, which doesn't have cooling on the VRM chips.
I'll be putting it in my PC tonight, along with a blu-ray drive.
EDIT:
It's installed and you just cannot hear it AT ALL over my case fans, even under max load.
I overclocked it to 800/1600/2000 and played an hour long session of Just Cause 2 with nearly everything at max except with no AA at 1680x1050, and it ran over 30fps constantly and the max temp was 64 degrees, with no noticable fan noise. Idle temp is about 36 degrees. I am very pleased indeed.
I got teh same 460 as you did and the gigabyte fans are superb for noise levels even under load. All I can hear is my CPU cooler fan...can't really hear the GPU at all. The gigabyte 460 is the absolute dog's balls
