I know noise is subjective, but you must have some loud case fans. In well ventilated case (Cooler Master Stacker 830) it would ramp up to 60-70% and sound like a vacuum cleaner. I submitted a ticket with Gigabyte asking if they had a BIOS with a quieter fan profile I could flash. They replied with one, but by then I'd sent it back. This was right after it was first released so subsequent cards might have had a different BIOS.
