If you're doing power cleans correctly you should not be dropping the weight. The movement isn't over until the weight is safely on the ground.
If the weight makes a noise loud enough to draw every gym goers attention, you are lifting too much and should deload. Or you just might be that guy ;)
This is 100% incorrect. In fact, there is a much higher risk of injury lowering a power clean under control, especially if you're going heavier.
That's not to say that you won't benefit from working with a weight where it is possible to control when lowering, but there's a lot to be said for power cleaning a higher amount and dropping upon completion of the rep.
Hah! This made me laugh. It's true, though. I used to think that the big dudes were just being obnoxious until I got up to that level, and realized that it's just incredibly fucking hard to lift that much weight. It takes a lot out of you, and the noises aren't for show.
Inexperienced lifters don't realize the incredible abdominal pressure you have to create for max effort lifts, the breathing control that goes with it, and the inevitable strange noises...
