So I'm here doing some work and thought I'd also get a couple of DVDs Handbraking. The noise of my fans going due to the increased heat is really doing my head in! Why can't I tell my Mac that this isn't urgent and doesn't need to be done asap? Why does it have to do everything as if I asked for it to be done yesterday? I'd rather it used less power, less heat and didn't make such a loud whirring all the time.
