As has been reported in some cases, even I can confirm that out of the box rattling can be heard in the case. The functions described do all their service, but the benefits are practically hardly available. Once both stages are active, the radiator is at least as loud as my laptop at full load, therefore I am running mostly of medium sized fan, which, however, only the closed case "anpustet". The product is more like a small highlight as it really brings a great advantage. When the device is in use, you can see the lights at most in the dark because yes it is the laptop. I could me already think that it makes more sense just to put my laptop on elevated feet, because as the air circulates better. Of course, the cooler also met, but to a much higher price than a few rubber feet.
