The only thing we really hate about all ATI hardware is the fact that fan rotates insanely fast when you boot a machine. We hate this, as the machine is incredibly noisy and this gets very annoying in the evenings. Does the cooler fan really need to rotate at the highest speed at startup?
Most Nvidia Cards do that too. Also Most Mainboards with Fan Control spin up the Connected Fans during Boot-time. This is something that originated from server Hardware. Spinning the Fans up to full speed every once in a while keeps the dust out of the Case and out of the Fins of Coolers. Makes a lot of sense.
