That's good, didn't know that.
Does make you wonder why they released it with too low a fan speed in the first place though.
Reviews mention that the initial cards (v3.0 i think) were shipped with stock AMD bios which ran the fan profile similar to what the reference cards have. The fan speeds were limited to 45% max which could be increased using afterburner or such. I think the new cards (v4.0?) have the updated bios.
